Answer:

Sin A= 5/13

Cos A= 12/13

Tan A= 5/12

Step-by-step explanation:

The memory trick most people use is for sin, cos, and tan, they call it SOH, CAH, and TOA where the A means Adjacent, the H means Hypotenuse and the O means Opposite. so sin would be Opposite/Hypotenuse, cos is Adjacent/Hypotenuse, and tan is Opposite/Adjacent.

Because the Hypotenuse is not given, we must use the formula A^2+B^2=C^2 where A is the height, B is the width, and C is the slope side. You will get C=13 if you do it correctly. Now you can solve for Sin, Cos, and Tan

Sin A= 5/13 (Opposite/Hypotenuse)

Cos A= 12/13 (Adjacent/Hypotenuse)

Tan A= 5/12 (Opposite/Adjacent)

Hope this helps.

Have a great day!

Sin(A) = opposite/hypotenuse = 12/13

Cos(A) = adjacent/hypotenuse = 5/13

Tan(A) = opposite/adjacent = 12/5

11) <br> Solve for x:<br><br> 3(7 + 2x) + 3 = 3(5 + x) − 9(x + 1)

gogolik [260]

Step-by-step explanation:

3(7 + 2x) + 3 = 3(5+ x) - 9(x + 1)

21 + 6x + 3 = 15 + 3x - 9x - 9

6x + 24 = 6 - 6x

12x = -18

x = -1.5

A map has a scale of 1 in : 3 km. If the actual distance is 15 km, what is the distance on the map?

Black_prince [1.1K]

Answer:

5 in.

Step-by-step explanation:

The ratio of map distance to real distance is 1 in : 3 km meaning that 1 inch on the map describes 15 km in real life.

15 km is 5 times 3 km, so the map distance is 5 times 1 in., or 5 in.

1 in. x 5 : 3 km x 5

This is a "school math" problem where things come out nicely! Another way to look at this is with equivalent fractions.

$\frac{\text{1 in}}{\text{5 km}} = \frac{\text{m}}{\text{15 km}}$

"cross multiply"

$5m = (15)(1)\\5m=15\\m=3 \text{ in.}$

Write an equation for the line in point-slope form passing through (-9, -7), parallel equation y=-2x+5

nika2105 [10]

Answer:

$y+7=-2(x+9)$

Step-by-step explanation:

step 1

Find the slope of the line

we know that

If two lines are parallel, then their slopes are the same

The slope of the given line is $m=-2$

therefore

The slope of the line parallel to the given line is $m=-2$

step 2

Find the equation of the line in point slope form

$y-y1=m(x-x1)$

we have

$m=-2$

$point\ (-9,-7)$

substitute

$y+7=-2(x+9)$

Which graph represent the function f(x)=4x^2

Leno4ka [110]

The graph of the function $f(x)=4x^2$ is a transformation of the graph of the parent function $f(x)=x^2$ ; more precisely, the graph of the function $f(x)=4x^2$ is the graph of the function $f(x)=x^2$ compressed by a factor of 4 in the $x$ direction.

Remember that we can compress or stretch the graph of a function in the $x$ direction by multiplying $x$ by a constant $c$ .
if $c\ \textgreater \ 1$ , we are compressing the graph in the $x$ direction.
if $0\ \textless \ c\ \textless \ 1$ , we are stretching the graph in the $x$ direction.

We can conclude that the graph of the function $f(x)=4x^2$ is the graph in the first picture. Also, in the second picture you will see the graph of both the function and its parent function simultaneously.
