Answer:

(g o f)(-10) = -11.

Step-by-step explanation:

To find the composition (g o f)(x), we need to substitute the function f(x) into g(x) and evaluate it at a specific value.

Given:

f(x) = (x - 2) / 6

g(x) = 8x + 5

To find (g o f)(-10), we substitute f(x) into g(x) and evaluate it at x = -10.

(g o f)(-10) = g(f(-10))

First, let's find f(-10):

f(-10) = (-10 - 2) / 6

= -12 / 6

= -2

Now, substitute f(-10) = -2 into g(x):

g(-2) = 8(-2) + 5

= -16 + 5

= -11

Therefore, (g o f)(-10) = -11.

Answer:

PQ+QN

Step-by-step explanation:

P*Q + Q*N

this is ans

The distance between points P and Q is √73

First, remember that the distance between two points whose coordinates are (a, b) and (c, d) is given by:

distance = √( (a - c)² + (b - d)²)

Here we can see that the coordinates of the two shown points are:

P = (-3, 2)

Q = (5, -1)

Replacing that in the distance formula we will get:

distance = √( (-3 - 5)² + (2 + 1)²)

distance = √( (-8)² + (3)²)

distance = √73

So the correct option is the third one.

Given:

To use the zero product property we have to rearrange the equation so that we can factor out two linear equations such that they give this format: a * b = 0

To start we multiply 5 and 6 to get 30

From here we will find common factors of 30 that they add up to -17.

30:

-1 -30

-2 -15

We stop here because -2 + -15 =-17 and when multiplied they get us +30.

So now:

Here is we can start to factor out the equation.

Since we have two (x-3) we can factor out the 5x and -2 into:

This is the zero product property and now we have to solve for x.

Answer:

Answer:

32 and 37

Step-by-step explanation:

Because the difference between the values is 5.

The equation 6( 3x + 4 ) + 2( 2x + 2 ) + 2 = 22x + 31 has no solution for the variable x.

Given the equation in the question:

6( 3x + 4 ) + 2( 2x + 2 ) + 2 = 22x + 31

To solve the equation 6(3x + 4) + 2(2x + 2) + 2 = 22x + 31 for the variable x, we will simplify and solve for x.

Apply distributive property:

6 × 3x + 6 × 4 + 2 × 2x + 2 × 2 + 2 = 22x + 31

18x + 24 + 4x + 4 + 2 = 22x + 31

Collect and combine like terms on both sides:

22x + 30 = 22x + 31

Next, we want to isolate the variable x on one side.

22x - 22x + 30 = 22x - 22x + 31

30 = 31

However, we notice that the x terms cancel out when subtracted:

30 ≠ 31

This means that there is no solution.

a. To determine whether the proportion of adults using social media is equal for all four countries, we can conduct a hypothesis test. The null and alternative hypotheses are as follows:

H0: The proportion of adults using social media is equal for all four countries

Ha: The proportion of adults using social media is not equal for all four countries

For the test, we will use a 0.05 level of significance.

b. The sample proportions for each of the four countries are as follows:

United Kingdom: P1 = 480 / (480 + 320) = 0.60

China: P2 = 215 / (215 + 285) = 0.43

Russia: P3 = 343 / (343 + 357) = 0.49

United States: P4 = 640 / (640 + 360) = 0.64

c. To conduct multiple pairwise comparison tests among the four countries, we will use the following formula:

Pi - Pj / √(P(1-P)(1/n1 + 1/n2))

Where Pi and Pj are the proportions for two countries, n1 and n2 are the sample sizes for two countries.

United Kingdom vs. China: Diff = 0.60 - 0.43 / √(0.51*0.49*(1/800 + 1/600)) = 0.17 / 0.03 = 5.67

United Kingdom vs. Russia: Diff = 0.60 - 0.49 / √(0.51*0.49*(1/800 + 1/700)) = 0.11 / 0.03 = 3.67

United Kingdom vs. United States: Diff = 0.60 - 0.64 / √(0.51*0.49*(1/800 + 1/1000)) = -0.04 / 0.03 = -1.33

China vs. Russia: Diff = 0.43 - 0.49 / √(0.57*0.43*(1/500 + 1/700)) = -0.06 / 0.04 = -1.50

China vs. United States: Diff = 0.43 - 0.64 / √(0.57*0.43*(1/500 + 1/1000)) = -0.21 / 0.04 = -5.25

Russia vs. United States: Diff = 0.49 - 0.64 / √(0.51*0.49*(1/700 + 1/1000)) = -0.15 / 0.03 = -5.00

Since the level of significance is 0.05 and all of the calculated differences in proportions are less than the critical value (1.96), we fail to reject the null hypothesis and conclude that there is no significant difference between the proportion of adults using social media in the four countries.

The remaining Kit volume in the syringe is sufficient to correct the dose to 20 mCi.

To solve this problem, we can use the concept of radioactive decay and the decay factor. Here's how we can calculate the required volume to correct the dose:

Determine the initial activity of the kit:

Initial activity = 180 mCi

Calculate the decayed activity at 9:30 (after 1.5 hours):

Decay factor = 0.841

Decay activity = Initial activity * Decay factor

Calculate the remaining activity after withdrawing 20 mCi at 8 am:

Remaining activity = Initial activity - 20 mCi

Calculate the remaining activity at 9:30:

Remaining activity at 9:30 = Remaining activity * Decay factor

Calculate the desired activity at 9:30 (20 mCi):

Desired activity at 9:30 = 20 mCi

Calculate the volume needed to achieve the desired activity:

Volume needed = Desired activity at 9:30 / Remaining activity at 9:30 * Volume at 9:30

Calculate the remaining volume at 9:30:

Remaining volume = Volume at 8 am - Volume withdrawn - Volume accidentally discharged

Calculate the volume that needs to be added:

Volume to be added = Volume needed - Remaining volume

Let's perform the calculations step by step:

Determine the initial activity of the kit:

Initial activity = 180 mCi

Calculate the decayed activity at 9:30 (after 1.5 hours):

Decay factor = 0.841

Decay activity = 180 mCi * 0.841 = 151.38 mCi

Calculate the remaining activity after withdrawing 20 mCi at 8 am:

Remaining activity = 180 mCi - 20 mCi = 160 mCi

Calculate the remaining activity at 9:30:

Remaining activity at 9:30 = 160 mCi * 0.841 = 134.56 mCi

Calculate the desired activity at 9:30 (20 mCi):

Desired activity at 9:30 = 20 mCi

Calculate the volume needed to achieve the desired activity:

Volume needed = (Desired activity at 9:30 / Remaining activity at 9:30) * Volume at 9:30

Volume at 9:30 = Remaining volume = 30 ml - (30 ml / 2) = 15 ml

Volume needed = (20 mCi / 134.56 mCi) * 15 ml = 2.236 ml

Calculate the remaining volume at 9:30:

Remaining volume = 30 ml - (30 ml / 2) = 15 ml

Calculate the volume that needs to be added:

Volume to be added = Volume needed - Remaining volume = 2.236 ml - 15 ml = -12.764 ml

Since the calculated volume to be added is negative, it means that no additional volume is required. The remaining Kit volume in the syringe is sufficient to correct the dose to 20 mCi.

  C:  y = -(x +3)² -1

Step-by-step explanation:

You want the vertex-form equation of the parabola with vertex (-3, -1) and opening downward.

For vertex (h, k), the vertex form equation of a parabola is ...

  y = a(x -h)² +k

Given that (h, k) = (-3, -1), the equation will have the form ...

  y = a(x -(-3))² + (-1)

  y = a(x +3)² -1 . . . . . . . . . . matches choice C

The value of 'a' will be negative when the parabola opens downward. Here, its value is -1.

  y = -(x +3)² -1

__

Additional comment

Once you identify the left-shift of 3 units as resulting in an equation with (x +3)² as a component, you can make the appropriate answer choice without considering anything else. Of course, the fact that the curve opens downward immediately eliminates choices A and B.

Answer:

Therefore, the correct statements are A, B, and E.

Explanation:

Based on my knowledge, a vector is a quantity that has both magnitude and direction. A scalar is a quantity that has only magnitude. When a vector is multiplied by a scalar, the magnitude of the vector is multiplied by the absolute value of the scalar, and the direction of the vector is either preserved or reversed depending on the sign of the scalar.

To answer your question, we need to find the component form, magnitude, and direction of the scalar product –4⇀

.

- The component form of −4⇀

is obtained by multiplying each component of ⇀

by –4. Therefore, −4⇀

= ⟨–8, –12⟩. This means that statement A is true.

- The magnitude of −4⇀

is obtained by multiplying the magnitude of ⇀

by 4. The magnitude of ⇀

is √(2^2 + 3^2) = √13. Therefore, the magnitude of −4⇀

is 4√13. This means that statement B is true.

- The direction of −4⇀

is opposite to the direction of ⇀

because the scalar –4 is negative. This means that statement C is false.

- The vector −4⇀

is in the third quadrant because its components are both negative. This means that statement D is false.

- The direction of −4⇀

is 180° greater than the inverse tangent of its components because it is opposite to ⇀

. The inverse tangent of its components is tan^(-1)(–12/–8) = tan^(-1)(3/2). Therefore, the direction of −4⇀

is 180° + tan^(-1)(3/2). This means that statement E is true.

Therefore, the correct statements are A, B, and E.

Answer:

You are only given a Side, an Angle, and then a side.  So that is what I would choose.  It can't be AA because you weren't given two angles.  It can't be SSS because you weren't given 3 sides.

Step-by-step explanation:

ΔPQR and ΔXYZ are similar due to the SSS theorem.

Option B is the correct answer.

There are ways to prove that two triangles are congruent.

- Side-Side-Side (SSS) Congruence.

The three sides of one triangle are equal to the corresponding three sides of another triangle.

- Side-Angle-Side (SAS) Congruence.

The two sides and the included angle of one triangle are equal to the corresponding two sides and included angle of another triangle.

- Angle-Side-Angle (ASA) Congruence.

The two angles and the included side of one triangle are equal to the corresponding two angles and included side of another triangle.

- Angle-Angle-Side (AAS) Congruence.

We have,

Similar triangles are triangles that have the same shape but may have different sizes.

Two triangles are similar if their corresponding angles are equal, and their corresponding sides are proportional.

When two triangles are similar, they have the same shape, but one may be larger or smaller than the other.

Now,

ΔPQR and ΔXYZ

PQ/XY = 12/4 = 3

PR/XZ = 6/2 = 3

Since the two sides are proportional,

QR/YZ will be proportional.

Now,

PQ/XY = PR/XZ = QR/YZ

ΔPQR and ΔXYZ are similar due to the SSS theorem.

Thus,

ΔPQR and ΔXYZ are similar due to the SSS theorem.
