Answer:

Area of red triangle =1/2 ×side a*side b

=½×90×120=5400ft²

The diver will be in the air for approximately 0.78 seconds to the nearest hundredth of a second.

The equation that represents the height of the diver above the surface of the pool is given by:

h(t) = -16t² + 6t + 33

where t is the time in seconds and h(t) is the height of the diver above the surface of the pool in feet.

The diver will be in the air until he reaches the surface of the pool, which means that his height will be 0. Therefore, we can set h(t) equal to 0 and solve for t:

-16t² + 6t + 33 = 0

We can use the quadratic formula to solve for t:

t = (-b ± sqrt(b² - 4ac)) / 2a

where a = -16, b = 6, and c = 33.

Plugging in these values, we get:

t = (-6 ± sqrt(6² - 4(-16)(33))) / 2(-16)

t = (-6 ± sqrt(36 + 2112)) / (-32)

t = (-6 ± sqrt(2148)) / (-32)

Simplifying:

t = (-6 ± 46.34) / (-32)

So we have two solutions:

t = (-6 + 46.34) / (-32) ≈ 0.78 seconds

t = (-6 - 46.34) / (-32) ≈ 2.64 seconds

Since the diver cannot be in the air for a negative amount of time, we reject the second solution.

Answer:

It is -0.465 when you add it to the nearest thousandth

Step-by-step explanation:

Hi there! You still remember the Pythagorean Theorem, right? It's useful when it comes to finding a missing leg or side of a right triangle. If you forget then here it is:

[tex] \large \boxed{ {a}^{2} + {b}^{2} = {c}^{2} }[/tex]

Define c = hypotenuse while a and b can be both adjacent and opposite (because a²+b²=b²+a² via addition property)

Since we are missing the adjacent side. Thus,

We define a = 6 and c = 14.

[tex] \large{ {6}^{2} + {b}^{2} = {14}^{2} } \\ \large{36 + {b}^{2} = 196} \\ \large{ {b}^{2} = 196 - 36} \\ \large{ {b}^{2} = 160} \\ \large{ b = \sqrt{160} \longrightarrow \boxed{b = 4 \sqrt{10} }}[/tex]

Put the value of b in a calculator then round to the nearest tenth and get 12.6

Thus, the value of b ≈ 12.6

Next we are going to find the angle in degree. We now know that b ≈ 12.6 or 4sqrt(10)

We can find the value of angle A by using tan or sin but I will use sin instead. Recall the sine ratio which is opposite to hypotenuse. Thus,

[tex] \large{sinA = \frac{6}{14} }[/tex]

Use arcsin(6/14) and put it in calculator.

Then put the decimal value of arcsin in sin and convert in degree form which we should get 24. 555°. Round to the nearest whole number and we get 25°

Thus, the angle A is 25°

Next is we are finding the value of angle B. We aren't going to use any formula or equation. Recall that three angles add up to 180°.

Thus, 25° + 90° + x = 180°

90° comes from a right angle.

115+x = 180

x = 180-115

x = 65°

Thus, the angle B is 65°

Step-by-step explanation:

it could be a combination of the two genders that can make them different :)

The equation that has the possible values of b is b² = 4.

The equation that has the possible value of b as -2 and 2 are as follows;

b² = 4

-2² = 4 and 2² = 4 (This is true)

b³ = 8

-2³ = -8 and 2³ = 8(This is false)

Therefore, the equation that has the possible values of b is b² = 4.

Answer:

each apple is £ 1.80

Step-by-step explanation:

i first multiplied the cost for one pear by 7, to get how much money was spent on pears out of the 12.70.

Then i took the remaining money and divided it by 2 to get how much each apple costs.

Answer:

1.80

Step-by-step explanation:

1) Price of Pears

[tex]1.30 * 7 = 9.10[/tex]          formating: 1.30*7 = 9.10

2) Price of Apples

[tex]12.70 - 9.10 = 3.60[/tex]          formating: 12.70-9.10 = 3.60

3) Price of Apples/Kg

[tex]\frac{3.60}{2} = 1.80[/tex]          formating: 3.60/2 = 1.80

Answer:

A. 10.4 mph

Step-by-step explanation:

26÷2.5=10.4

Double checking your answer:

If she does 10.4 miles in an hour, she can get 20.8 in two hours

then you add half of how much she can go in an hour which is 5.2 (10.4÷2)

you add it together, and you will get 26 miles in total

(20.8+5.2=26)
