Answer:
9.5 = y
Step-by-step explanation:
You have to use the cosine function equation.
cos(38) = [tex]\frac{y}{12}[/tex]
Multiply 12 on both sides.
12cos(38) = y
Solve.
9.46 = y
Answer:
9.5
Step-by-step explanation:
y is the adjacent side of the given 38 degree angle. You are given the hypotenuse of right angle triangle. So the trig function that you need to use is the Cosine
Cos(38) = y / 12
multiply both sides by 12
12*cos(38) = 12*y/12
12*cos(38) = y
12*0.7880= y
y =9.456

The Graph transformation of [tex]f(x) = 7^x[/tex] which stretched vertically by a factor of five is [tex]g(x) = 5(7^x)[/tex] .
What is graph transformation?Graph transformation is the process by which an existing graph, or graphed equation, is modified to produce a variation of the proceeding graph .
According to the question
The graph of [tex]f(x) = 7^x[/tex] stretched vertically by a factor of five .
i.e
we have to make change is graph equation so y axis changes 5 times .
Therefore ,
[tex]f(x) =( 7^x ) * 5[/tex]
The Graph transformation of f(x) is
[tex]g(x) = 5(7^x)[/tex]
Hence, the Graph transformation of [tex]f(x) = 7^x[/tex] which stretched vertically by a factor of five is [tex]g(x) = 5(7^x)[/tex]

Which option correctly shows how this formula can be rearranged to isolate x^2?
Options in picture.
Answers
Answer:
A
Step-by-step explanation:
We have:
[tex]\displaystyle m=\frac{x_1-x_2}{y_1-y_2}[/tex]
And we want to isolate x₂.
So, let’s first remove the denominator by multiplying both sides by it:
[tex]\displaystyle m(y_1-y_2)=\frac{x_1-x_2}{y_1-y_2}(y_1-y_2)[/tex]
The right side will cancel. This will leave:
[tex]\displaystyle m(y_1-y_2)=x_1-x_2[/tex]
Now, we can subtract x₁ from both sides. So:
[tex]\displaystyle m(y_1-y_2)-x_1=-x_2[/tex]
Finally, we will multiply both sides by -1. So:
[tex]\displaystyle x_2=-m(y_1-y_2)+x_1[/tex]
Hence, our answer is A.

Mr. Randall, a salesperson, earns a weekly salary of $300 plus a commission of 7% of
his weekly sales of merchandise. Last week, Mr. Randall earned $426. This can be
represented by the equation below, where s represents his total sales, in dollars, for
the week.
$300 + $0.07s = $426
How many dollars worth of merchandise did Mr. Randall sell last week?
Answers
Answer:
-3
Step-by-step explanation:
Based on his weekly salary and commission, we can calculate that Mr. Randall sold goods worth $1,800.
In the formula given, sales is represented as s. To find the total sales, you can solve the equation:
300 + 0.07s = 426
0.07s = 426 - 300
s = 126 / 0.07
= $1,800
In conclusion, Mr. Randall sold $1,800 worth of goods.

Answer:
4.00 feet48 inches8 pictures4 picturesStep-by-step explanation:
1. The available wall space is the difference between the length of the wall and the length of the window:
9.75 ft - 5.75 ft = 4.00 feet
__
2. At 12 inches per foot, this is ...
(4 ft)(12 in/ft) = 48 in
__
3. If the pictures are 6 inches wide, Mr. Smith can use ...
(48 in)/(6 in/picture) = 8 pictures
__
4. If the pictures are 10 inches wide, Mr. Smith can use ...
(48 in)/(10 in/picture) = 4.8 pictures
There is room for 4 pictures. Space for a fraction of a picture is not useful. This number is even, so 4/2 = 2 pictures can be placed on either side of the window.

since the triangles have congruent angles, the sides have a relationship too. Basically, the ratio between the triangle is 4:10 because those sides math up. So, that also means it is 2:5. Therefore, BC:EC=6:15. 15-12.5=2.5, so x=2.5.
Now you can just do 2.5+5=7.5 so DC=7.5
