Answer to question 1 would be g(x) is translated 6 units down from f(x)

When the number at the end is subtraction and it is outside of the parenthesis

then you are dealing with a translation of x units down.

If you were adding the 6 to x it would be a translation of 6 units up.

Now the same applies with left to right but the difference with that is if x is subtracted or added to 6 in the same parenthesis.

So process of elimination leads us to answer A for question 1.

Question 2. The answer would be C.

When dealing with vertical stretch you would have to be multiplying the factor to g(x).

When dealing with vertical compression you would need to do y=1/a f(x)

Process of elimination leads us to Answer choice C

Find the perimeter of the object Help step by step please!

aliina [53]

Answer:

29.42 units

Step-by-step explanation:

1) Find the perimeter around the semi-circle

To do this, we find the circumference of the circle using the given diameter:

$C=\pi d$ where d is the diameter

Plug in 6 as the diameter

$C=\pi (6)\\C=6\pi$

Divide the circumference by 2

$\frac{6\pi }{2} \\= 3\pi$

Therefore, the perimeter around the semi-circle is 3π units.

2) Find the perimeter around the rest of the shape

Although it's impossible to determine the lengths of the varied sides on the right side of the shape, we know that all of those vertical sides facing the right add up to 6. We also know that all of those horizontal sides facing up add up to 7. Please refer to the attached images.

Therefore, we add the following:

7+6+7

= 20

Therefore, the perimeter around that area of the shape is 20 units.

3) Add the perimeter around the semi-circle and the perimeter around the rest of the shape

$20+3\pi \\= 20+9.42\\= 29.42$

Therefore, the perimeter of the shape is approximately 29.42 units.

I hope this helps!

1 fourth B minus 10 equals 7

creativ13 [48]

$\frac{1}{4}$ b - 10 = 7
Take 10 to the other side.

$\frac{1}{4}$ b = 17

Multiply by 4 to isolate b
$\frac{1}{4}$ b × 4 = 17 × 4

4 and 4 cancels out

b = 68

Identify the variation as direct inverse joint or combined. The cost of the number of the same articles purchased varying with t

olasank [31]

This is a direct variation, since the cost and the number of articles purchases both go up.

If AB= 5 what is the exact length of BD in square ABCD

Afina-wow [57]

Answer:

sqrt 50

Step-by-step explanation:

First of all this is a square so if AB = 5, then AD is also 5.

Let's get rid of the other triangle and only focus on triangle ABD.

Using Pythagorean theorem we are able to solve this problem.

The Pythagorean Theorem basically states that:

a^2 + b^2 = c^2

Where a and b are the legs and c is the hypotenuse, aka the thing that we are trying to solve for right now.

Substitute these numbers in: 5^2 + 5+2 = c^2

Solve: 50 = c^2

c= sqrt 50

^ and that is our answer!
