Steve puts an 18-foot ladder against his house. The ladder reaches a height of 15 feet on the house. How far is the bottom of the ladder from the base of the house? Leave the answer as a simplified square root.
Answers
Answer:
\(3 \sqrt{11} \)
Step-by-step explanation:
Since we are given the hypotenuse which is 18 since it slanted, and leans on the house. And we are given one of the legs which is 15 since it is vertical. We can use the pythagorean theorem to solve for this problem.
\( {a}^{2} + {b}^{2} = c {}^{2} \)
where a and b are the legs and c is the hypotenuse l.
Let plug it in
\( {a}^{2} + 15 {}^{2} = {18}^{2} \)
\( {a }^{2} + 225 = 324\)
\( {a}^{2} = 99\)
\(a = \sqrt{99} \)
\(a = \sqrt{9 \times 11} \)
\(a = 3 \sqrt{11} \)

"Three times a certain number minus 12 is equal to twice that number added to 36."The value of the number is 48.
To find the value of the number, let's assign a variable to represent the unknown number. Let's call it "x".
According to the given information, "Three times a certain number minus 12 is equal to twice that number added to 36." This can be written as the equation:
3x - 12 = 2x + 36
To solve for x, we can simplify the equation by combining like terms:
3x - 2x = 36 + 12

92.3- (3.2 ÷ 0.4) × 2³
Answers
Answer:
28.3
Step-by-step explanation:
To solve this problem, we must follow PEMDAS, which must be used in solving all mathematical equations and expressions.
PEMDAS is the order you solve the equation/expression in. It is an acronym for:
P: Parenthesis
E: Exponents
M: Multiplication
D: Division
A: Addition
S: Subtraction
Keep in mind that multiplication and division are too be done left and right. You do not do multiplication first and division last, read left to right. Same goes with addition and subtraction.
This is the less confusing notation of PEMDAS.
P: Parenthesis
E: Exponents
M: Multiplication D: Division
A: Addition S: Subtraction
Now, lets solve the problem.
92.3 - (3.2 ÷ 0.4) × 2³
What do we do first? Well since parenthesis is first according to PEMDAS, we must solve the division in side of the parenthesis first.
3.2/0.4 = 8
Now we have:
92.3 - (8) × 2³
Remove the parenthesis as there is only one term inside and therefore not needed.
92.3 - 8 × 2³
What do we do next?
We have:
Subtraction: 92.3 - 8
Multiplication: -8 × 2³
Exponent: 2³
Because PEMDAS states exponents is to be solved in front of multiplication/division and addition/subtraction, we must do that.
What is an exponent?
2³
2 is the base, 3 is the exponent.
2³
Means multiplying 2 by itself 3 times:
2 × 2 × 2
8
Now we have:
92.3 - 8 × 8
Because PEMDAS states solving multiplication/division is prioritized over addition/ subtraction, we must solve 8 × 8
8 × 8 = 64
Now we have: 92.3 - 64
Solve.

x=±√7
Step-by-step explanation:
Hi there!
We're given the quadratic equation 6x²-42=0 and we need to find the roots of the equation (the values of x that make the equation true).
So we need to isolate x onto one side.
We can start by adding 42 to both sides
6x²=42
divide both sides by 6
x²=7
Now, take the square root of both sides (remember that when we take the square root, we get both POSITIVE and NEGATIVE answers).
x=√7 and x=-√7 (can be rewritten as x=±√7)
Hope this helps! :)
Answer:
Step-by-step explanation:
6x the ''2'' is supposed to be a exponent all the time -42=0

A sprinkler set in the middle of a lawn sprays in a circlular pattern the area of the lawn that gets sprayed by the sprinkler can be described by the equation (x-2)y+(y-5)2=169
Answers
To see why, we can rewrite the equation in standard form for a circle:
(x-2)y+(y-5)²=169
xy - 2y + y² - 10y + 25 = 169
x(y-2) + y² - 10y - 144 = 0
(x-(-2))(y-5)² = 144
(x+2)(y-5)² = 144
This is the equation of a circle with center (-2, 5) and radius 12. Therefore, the area of the lawn that gets sprayed by the sprinkler is a circle with center (-2, 5) and radius 12.

The correct order from best to worst of the sample groups is b→ a→ c.

There are 3 sample groups selected from the population of Anytown residents with an active interest in sports. They are:
a. High-school students at three different schools.
b. People randomly approached at a softball tournament, a swim meet, an athletic supply store, and a sports bar.
c. People randomly approached at a department store and at a shopping mall
All these groups are selected randomly.
But for (b), the people are obviously interested in sports activities, as they are selected from softball tournament, a swim meet, an athletic supply store, and a sports bar.
Next would be (a), because the students being younger is probably more interested in sports than elder ones.
The last would be the (c), people selected from the department store since they would be less aware of local- sports related activities.
So the order of samples from best to worst is b→ a→ c.
