The function h(t) = −5t2 + 15t shown in the graph models the supporting structure of a bridge:

BabaBlast [244]

Since the function is h(t) = −5t² + 15t, the domain of the function h(t) is 0 ≤ t ≤ 3

<h3>What is the domain of a function?</h3>

The domain of a function is the range of input values that make the function have real values.

Now given the function h(t) = −5t² + 15t, it will have real values when

h(t) ≥ 0

So, h(t) ≥ 0

⇒ −5t² + 15t ≥ 0

Factorizing, we have

-5t(t - 3) ≥ 0

5t(t - 3) ≤ 0

t(t - 3) ≤ 0

t ≤ 0 and t - 3 ≤ 0

t ≤ 0 and t ≤ 3

For t ≤ 0, say -1, t(t - 3) = -1(-1 - 3) = -1(-4) = 4 ≥ 0

For 0 ≤ t ≤ 3, say 2, t(t - 3) = 2(2 - 3) = 2(-1) = -2 ≤ 0

For t ≥ 3, say 4, t(t - 3) = 4(4 - 3) = 4(1) = 4 ≥ 0

Since we require t(t - 3) ≤ 0, the domain of t is thus 0 ≤ t ≤ 3

So, the domain of the function h(t) is 0 ≤ t ≤ 3

Find the unknown length x in the right triangle, to the nearest tenth .

VARVARA [1.3K]

Answer:

x = 11.7

Step-by-step explanation:

sin of an angle is opposite/hypotenuse

sin 38 = x/19

x = 19 sin 38

x = 11.7

You need to memorize the definitions of all the trig functions and then this type of problem will be easy for you.

The tennis team is selling tickets to wash for six dollars. And they don't do not sell very much tickets, the team decreases the

schepotkina [342]

Answer:

The new cost of tickets after decrease of price at 23 % rate is $ 4.62

Step-by-step explanation:

Given as :

The initial cost of the selling tickets = $ 6

Let The final cost of selling tickets = $ x

The rate of decrease of ticket price = 23 %

Now,

The final cost of tickets = initial cost of tickets × ( 1 - $\dfrac{\textrm rate}{100}$ )

or, $ x = $ 6 × ( 1 - $\dfrac{\textrm 23}{100}$ )

or, x = $ 6 × $\frac{77}{100}$

∴ x = $ 4.62

So decrease price = x = $ 4.62

Hence The new cost of tickets after decrease of price at 23 % rate is $ 4.62 Answer
