Answer:

Step-by-step explanation:

problem 4

Velocity is +2.0m/s and constant acceleration is -0.5m/s^2

For every second the velocity drop by 0.5 m/s, so after 2 seconds the velocity is 1 m/s.

problem 5

Accelerate from rest to 28m/s means go from 0 to 28m/s so with

a constant acceleration of 5.5 m/s^2 it will take 5.09 second

How to find the missing angle of a triangle using trig when you only know 1?

Sedbober [7]

If you have

2 KNOWN sides & 1 Angle ;
Use Cosine Rule

If you have 3 KNOWN sides,
Also Cosine Rule

If you have

2 KNOWN angles & 1 side,
Use SINE rule

If it's a right-angled triangle, use SOH CAH TOA

Hopefully this helps

How is the graph of the parent function of y = RootIndex 3 StartRoot 0.5 x EndRoot transformed to produce the graph y = RootInde

lana66690 [7]

Answer:

Horizontal stretch by a factor of ½.

Step-by-step explanation:

We were given the parent function as:

$y = \sqrt[3]{0.5x}$

This was transformed to:

$y = \sqrt[3]{x}$

Let

$g(x) = \sqrt[3]{0.5x}$

and

$f(x) = \sqrt[3]{x}$

Then:

$f(x) = g(2x)$

Hence the parent function has been stretched horizontally by a factor of 1/2 to obtain the transformed function.

Passes through (8,8) and (10,9) Plz help need answer ASAP

dalvyx [7]

Answer:

y = $\frac{1}{2}$ x + 4

Step-by-step explanation:

Assuming you require the equation of the line.

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (8, 8) and (x₂, y₂ ) = (10, 9)

m = $\frac{9-8}{10-8}$ = $\frac{1}{2}$ , then

y = $\frac{1}{2}$ x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (8, 8) , then

8 = 4 + c ⇒ c = 8 - 4 = 4

y = $\frac{1}{2}$ x + 4 ← equation of line

Answer:

40 m^3

Step-by-step explanation:

Volume of a pyramid = 1/3 * base area * height

base area = 4 x 4

1/3 * (4x4) * 7.5 = 40 m^3
