A ball is thrown into the air by a baby alien on a planet in the system of Alpha Centauri with a velocity of 43 ft/s. Its height

Lina20 [59]

Answer:

Instantaneous Velocity at t = 1 is 20 feet per second

Step-by-step explanation:

We are given he following information in the question:

$y(t)=43t-23t^{2}$

B) Instantaneous Velocity at t = 1

$y(1) = 43(1)-23(1)^2 = 20$

A) Formula:

Average velocity =

$\displaystyle\frac{\text{Displacement}}{\text{Time}}$

1) 0.01

$y(1 + 0.01)=y(1.01) = 43(1.01)-23(1.01)^{2} = 19.9677\\\\\text{Average Velocity} = \dfrac{y(1.01)-y(1)}{1.01-1} =\dfrac{19.9677-20}{1.01-1}= \dfrac{-0.0323}{0.01} = -3.230000 \text{feet per second}$

2) 0.005 s

$y(1 + 0.005)=y(1.005) = 43(1.005)-23(1.005)^{2} = 19.984425\\\\\text{Average Velocity} = \dfrac{y(1.005)-y(1)}{1.005-1} =\dfrac{19.984425-20}{1.005-1} = -3.1150000 \text{feet per second}$

3) 0.002 s

$y(1 + 0.002)=y(1.002) = 43(1.002)-23(1.002)^{2} = 19.993908\\\\\text{Average Velocity} = \dfrac{y(1.002)-y(1)}{1.002-1} =\dfrac{19.993908-20}{1.002-1} = -3.0460000 \text{feet per second}$

4) 0.001 s

$y(1 + 0.001)=y(1.001) = 43(1.001)-23(1.001)^{2} = 19.996977\\\\\text{Average Velocity} = \dfrac{y(1.001)-y(1)}{1.001-1} =\frac{19.996977-20}{1.001-1} = -3.0230000 \text{feet per second}$

Both triangles are similar. The area of the larger triangle is about 382 ft2. Which is the best approximation for the area of th

melisa1 [442]

Answer: SECOND OPTION

Step-by-step explanation:

You must find the ratio of the sides of the triangle, as following:

$r=\frac{30}{42}=\frac{5}{7}$

Therefore, the ratio of the areas is:

$r_A=(\frac{5}{7})^{2}\\\\r_A=\frac{25}{49}$

Now you must multiply the area of the larger triangle by the ratio obtained above, therefore, you have that the result is:

$A_s=(382ft^{2})(\frac{25}{49})=194.89ft^{2}$ ≈ $195ft^{2}$

If the angle measure of the section for giraffes is 72∘, how many students said giraffes were their favorite zoo animal?

laiz [17]

Answer:

12 students

Step-by-step explanation:

Here is the complete question

Alex surveyed 60 students about their favorite zoo animals and made the circle graph of the results shown below. A circle graph titled Favorite Zoo Animals is shown. There are five sections. One section is labeled Bears, one section is labled Lions, one section is labeled Monkeys, one section is labeled Elephants, and one section is labeled Giraffes.

If the angle measure of the section for giraffes is 72∘, how many students said giraffes were their favorite zoo animal?

Number of students that said the giraffe was their favorite zoo animal = (angle measuring the section for giraffes / sum of angles in a circle graph) x number of students surveyed

the sum of angles in a circle = 360 degrees

(72 / 360) x 60 = 12 students
