The function h =-16t^2 +1000 gives an objects height, h in feet, at t seconds When will the object be 1000 feet above the ground?
How many seconds did it take for the object to hit the ground?
How many seconds did it take for the object to reach 1000 feet

Answers

Answer:

time = 0 seconds

Time to hit ground = 7.906 seconds

time = 0 seconds

Step-by-step explanation:

t = 0

-16(0)^2 +1000 = 1000

Time for ball to reach ground:

-16t^2 +1000 = 0

-16t^2 = -1000

t^2 = -1000/-16

t = squareRoot (-1000/-16) = 7.906 seconds

Santino bought a book for $23.54. The price of the book was $22. What was the sales-tax rate?

Answers

We first find value of tax in dollars.

The difference between the two prices  is: 23. 54 - 22 = 1.54

Therefore the sales tax in dollars is 1.54

The tax % will be  (amount of tax / original cost price ) × 100

(1.54 / 22) × 100 → (0.07) × 100 =  7

So the tax rate is 7%

We can double check the answer.

7 % of 22  → (7/100) × 22 → 0.07 × 22 = 1.54

22 + 1.54 = 23.54

Area of triangle is, 351. 39 cm²

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

We have to given that;

All the sides of triangles are,

⇒ 30 cm, 30 cm, and 26 cm

We know that;

Area of triangle = √ s (s - a) (s - b) (s - c)

Where, 's' is the semi perimeter of the triangle, and a, b and c are three sides of triangle.

Here, Sides are,

⇒ a = 30

⇒ b = 30

⇒ c = 26

Hence, We get;

⇒ s = (a + b + c) / 2

⇒ s = (30 + 30 + 26) / 2

⇒ s = 86 / 2

⇒ s = 43 cm

So, The area of triangle is,

⇒ Area of triangle = √ s (s - a) (s - b) (s - c)

⇒ Area of triangle = √ 43 (43 - 30) (43 - 30) (43 - 26)

⇒ Area of triangle = √ 43 × 13 × 13 × 17

⇒ Area of triangle = 13 √ 731

⇒ Area of triangle = 13 × 27.03

Area of triangle = 351. 39 cm²

Answer:

351.48cm²

Step-by-step explanation:

Heron’s Formula

Find half the perimeter (30+30+26)/2=43

It’s the square root of each side subtracted from 43, multiplied together, times 43.

√(43-30)*(43-30)*(43-26)*43=√13*13*17*43=√=123539=351.481cm²

during a bike challenge, riders have to collect various colored ribbons. each 1/2 mile they collect a red ribbon, each 1/8 mile they collect a green ribbon, and each 1/4 mile they collect a blue ribbon. which colors of ribbons will be collected at the 3/4 mile marker?

Answers

The correct answer is:
green and blue.

Explanation:
We want to see which fractions 
(3)/(4) is a multiple of. We know that (3)/(4) is a multiple of (1)/(4), because (1)/(4)*3=(3)/(4).

We can divide fractions to determine if (3)/(4) is a multiple of (1)/(2):
( (3)/(4))/( (1)/(2));

in order to divide fractions, flip the second one and multiply:
(3)/(4))*(2)/(1)=(6)/(4)=1 (1)/(2).
This did not divide evenly, so (3)/(4) is not a multiple of 1/2.

Checking to see if (3)/(4) is a multiple of (1)/(8), ( (3)/(4))/( (1)/(8));

flip the second one and multiply:
(3)/(4)*(8)/(1)=(24)/(4)=6.
This divided evenly, so (3)/(4) is a multiple of (1)/(8).

Answer: Hello there!

As we know, each 1/2 mile there is a red ribbon, each 1/8 mile there is a green ribbon, and each 1/4 mile there is a blue ribbon.

We want to know which color of ribbons is in the 3/4 mile marker.

then we need to see if 3/4 is a multiple of some of the previous numbers.

Start with the red ribbons, we need to see the quotient between 3/4 and 1/2, if the result is a whole number, then 3/4 is a multiple of 1/2

this is q = (3/4)/(1/2) = (3/4)*2 = 6/4

here we haven't a whole number, then there is no red ribbon at the 3/4 mile marker.

now with the green ones:

(3/4)/(1/8) = (3/4)*8 = 24/4 = 6

there we have a whole number, this means that at the 3/4 mile marker, we will see the sixth green ribbon, then we have a green ribbon in this marker.

now with the blue:

(3/4)/(1/4) = (3/4)*4 = 3

At the 3/4 mile marker, we will see the third blue ribbon, then there is a blue ribbon in this marker.

Then we know that in the 3/4 mile marker, there are a green and a blue ribbon.
