THEOREM:

h² = p² + b² where h is hypotenuse, b is base and p is perpendicular.

ANSWER:

[3] By pythagorean theorem,

x² = 14² + 9²
x² = 196 + 81
x² = 277
x = √277
x = 16.64 rounded.

[4] By pythagorean theorem,

x² = 32² + 24²
x² = 1024 + 576
x² = 1600
x = √1600
x = 40.

[5] By pythagorean theorem,

(2x)² = 21² – 12.6²
4x² = 441 – 158.76
4x² = 284.24
x² = 284.24/4 = 70.56
x = √70.56
x = 8.4

[6] By tangent property,

7x – 29 = 2x + 16
7x – 2x = 16 + 29
5x = 45
x = 9.

So, WX = 7(9) – 29 = 63 – 29

WX = 34

Solve the system of equations x+4y=15 2x-y=-15

Lady_Fox [76]

x+4y=15 2x-y=-15

We have to make x neg.

-2(x) + 4y (-2)= -2(15)

-2x-8y=-30

2x-y=-15

-9y= -45

Solve for y

Y=-45/-9

Y = 5

Substitute your y answer into one original equation to find x .

x+4y=15

X+4(5)=15

X+20=15

X=15-20

X= -5

Answer is (-5,5)

Given a polynomial function f(x), describe the effects on the y-intercept, regions where the graph is increasing and decreasing,

alina1380 [7]

Answer:

We are have the function f(x).

Part 1: It is given that the function f(x) is transformed to f(x)+2.

This gives us that the function is translated 2 units upwards.

As, the y-intercept of f(x) is f(0). So, the y-intercept of f(x)+2 is f(0)+2, which is also translated 2 units up.

Translation does not change the behavior of the function.

So, if f(x) is increasing (or deceasing), then f(x)+2 will be increasing(or decreasing) respectively.

Moreover, f(x)+2 will be even or odd if f(x) is even or odd respectively.

Part 2: It is given that the function f(x) is transformed to $\frac{-1}{2}f(x)$

This gives us that the function is shrinked vertically by a factor of $\frac{1}{2}$ followed by a reflection across x-axis.

Also, the y-intercept of is $\frac{-1}{2}f(0)$ .

The graph of f(x) after changing to $\frac{-1}{2}f(x)$ will flip over the x-axis.

So, the function $\frac{-1}{2}f(x)$ will increase or decrease when f(x) decrease or increase respectively.

Moreover, $\frac{-1}{2}f(x)$ will be even if f(x) is even or odd respectively.
