The person is traveling 30 mph.

The car is traveling 45 mph.

Just mulitply 15 x 3 and 10 x 3.

Let’s break the numbers down.

10 + 5 = 15. So we can break 15 down like how you add 15.

10 x 3 = 30.

5 x 3 = 15.

Let’s add 30 and 15 together.

30 + 15 = 45.

Let’s now multiply 10 and 3.

10 x 3 = 30.

I hope this helped!

A baseball is thrown in a parabolic arc. It's position above the ground at a given point in time can be represented by the quadr
SCORPION-xisa [38]

Answer:

The baseball reached 9 feet high above the ground

Step-by-step explanation:

The given quadratic function representing the position of the baseball above ground is p(t) = 1/2·g·t² + v₀·t + p₀

Where;

t ≥ 0

g = -32 ft./sec²

v₀ = The initial velocity

p₀ = The initial position

Given that when the ball is thrown, we have;

The initial, straight up, velocity, v₀ = 16 ft./sec

The initial position, p₀ = 5 ft.

Substituting the above values in the quadratic function representing the position of the baseball above ground, we have;

p(t) = 1/2·(-32)·t² + 16·t + 5 = 16·t - 16·t² + 5

At the maximum point, the rate of change of the height with time = 0, therefore;

dp(t)/dt = 0 = d(16·t - 16·t² + 5)/dt = 16 - 32·t

16 - 32·t = 0

16 = 32·t

t = 16/32 = 0.5 seconds

Therefore, the time takes to reach the maximum height = 0.5 seconds

The height (maximum) reached in 0.5 seconds is given as follows;

h(t) = 16·t - 16·t² + 5, from which we have;

h(0.5) = 16 × 0.5 - 16 × (0.5)² + 5 = 9

Therefore, the height baseball reached = 9 ft. above ground

Help! What’s the measure of angle RST? Please explain, I want to learn.
KatRina [158]
The angle where the letter S is which would be angle RSQ = 1/2 x (131 +43) = 87

the angle opposite os RSQ would be PST and that would equal the same as RSQ which is 87

so 2 angles = 87 +87 = 174
 
so the other 2 angles need to equal 360 - 174 = 186

 since opposite angles equal each other divide that by 2 so 186 / 2 = 93

so both angle RST and PSQ are 93

The answer is D 93 degrees

EASY BUNCH OF POINTS &amp; WILL GIVE BRAINLIEST:) Find the distance FG between the points F(2,7) and G(4, -1). Round your answer
FrozenT [24]

Answer:

If the flask shown in the diagram can be modeled as a combination of a sphere and a cylinder, then its volume is

Use following formulas to determine volumes of sphere and cylinder:

wher R is sphere's radius, r - radius of cylinder's base and h - height of cylinder.

Then

Answer 1: correct choice is C.

If both the sphere and the cylinder are dilated by a scale factor of 2, then all dimensions of the sphere and the cylinder are dilated by a scale factor of 2. So

R'=2R, r'=2r, h'=2h.

Write the new fask volume:

Then

Answer 2: correct choice is D.
