Fireworks are set off from a hill 80 feet above the Mississippi. The outer
shells will fall after exploding at its maximum height. The firework's height
about the surface of the river is given by the function h(t) = -16t^2 + 64t +
80. What is the height of the rocket after 1.5 seconds?

Answer: False

Step-by-step explanation: Similar means that only the angles are the same, but the sides are not. Congruent means the angles and sides are the same.

Answer:

y = 110

Step-by-step explanation:

ABCD is a cyclic quadrilateral ( its vertices are on the circle )

The opposite angles are supplementary, sum to 180° , then

∠ C = 180° - 70° = 110° , thus

y = 110

Answer:

850.9 feet

Step-by-step explanation:

The horizontal distance between Ryan and the dolphin is 850.907 feet.

One area of mathematics known as trigonometry examines the relationship between the sides and angles of a right triangle. The relationship between sides and angles is defined for 6 trigonometric functions.

We have,

Ryan is 228 feet above the water and the angle of depression to the dolphin is 15.

Using trigonometry

tan 15 = 228/ x

x= 228/ tan 15

x= 228 / 0.26794919243

x = 850.907  feet

Answer:

A. y > -3 All real numbers greater than -3

Step-by-step explanation:

there are 15 sets that need to be played in the tournament. To list all the sets, we can simply list all the possible combinations of 2 players from the group of 6.

What is the combination?

In simple words, combination involves the selection of objects or things out of a larger group where order doesn't matter. The formula for combination helps to find the number of possible combinations that can be obtained by taking a subset of items from a larger set.

There are a total of 6 players in the round-robin racquetball tournament, which means that each player will play a set against each of the other 5 players.

To determine the total number of sets that need to be played, we can use the combination formula:

nC₂ = (n*(n-1))/2

where n is the number of players.

In this case, n = 6, so:

6C₂ = (6*(6-1))/2 = 15

Hence, there are 15 sets that need to be played in the tournament. To list all the sets, we can simply list all the possible combinations of 2 players from the group of 6:

Step 1

[tex]7x - 2 + 2 = 26 + 2 \\ 7x + 0 = 28 \\ 7x = 28 \\ x = \frac{28}{7} \\ x = 4[/tex]

Step 2 (Optional)

Answer: 3

Step-by-step explanation:

The larger triangle is 5 times the size of the smaller triangle. Notice 6 increased to 30. How? 5x6 = 30, so it increased in size 5 times. The rise of the larger triangle is 15. If we know that 15 is 5 times as large as the smaller rise, then 15 divided by 5 = 3. So the smaller rise is 3

Answer:

Missing rise is 3

Answer:

£ 6,564.70

Step-by-step explanation:

Henry places £6000 in an account which pays 4.6% compound interest each year. Calculate the amount in his amount after 2 years

Compound Interest formula =

A = P(1 + r/n)^nt

A = Final Amounrt

P = Principal = £6,000

r = Interest rate = 4.6%

t = Time in years = 2 years

n = Compounding frequency = Yearly = 1

First, convert R percent to r a decimal

r = R/100

r = 4.6%/100

r = 0.046 per year,

Then, solve our equation for A

A = P(1 + r/n)^nt

A = 6,000.00(1 + 0.046/1)^(1×2)

A = £ 6,564.70

The amount in his account after 2 years = £ 6,564.70
