Answer:
8.2 meters
Step-by-step explanation:
This problem will form a Right angle triangle.
Where;
6.4 m and 5.2 m are the adjacent and opposite sides of the triangle while the distance that Lillian needs to throw the ball to get it to Jenna is the hypotenuse of the right angle triangle. Thus;
h = √(6.4² + 5.2²)
h = √68
h = 8.2

Answer:
1. B = 61.5 ft²2. h = 12 ft3. V = 738 ft³Step-by-step explanation:
Firsly ,we notice that the base of the prism is a regular pentagon
regular means the five sides of the pentagon are equal in measure .
_______
Formula :
Area of a regular pentagon B = 1/2 × p × a;
where p is the perimeter of the pentagon
a is the apothem of the pentagon
_______________________________
then p = 5×6 = 30 ft
a = 4.1 ft. (Given)
therefore ,
B = 1/2 × p × a
= (1÷2) × 30 × 4.1 = 61.5 ft²
height of the prism h = 12 ft (given)
Volume V = B × h = 61.5 × 12 = 738.ft³

Find the value of each trigonometric ratio. Simplify
Please help with both precalc questions! 2 dif problems
Answer:
Step-by-step explanation:
For the first problem you have:
[tex]sin^2(x)-sin(x)=0[/tex]
Factor out a sin(x) to get:
[tex]sin(x)[2sin(x)-1]=0[/tex]
Individually, set both terms equal to zero:
[tex]sin(x)=0[/tex]
[tex]2sin(x)-1-0[/tex]
The first equation is asking "sine of what angle gives zero?" The sine of 0 will give zero, and so will the sine of pi, and 2pi, etc. Therefore, you can generalize this by saying the solution is pi multiplied by an integer 'n' where 'n' can be from zero to infinity:
[tex]x=n\pi[/tex]
where n = 0, 1, 2, 3, 4, 5, etc..
(make sure you specify that 'n' can equal zero.)
For the second equation, add 1 to both sides to get:
[tex]2sin(x)=1[/tex]
Divide both sides by 2 to get:
[tex]sin(x)=\frac{1}{2}[/tex]
Sine of what gives 1/2? Sine of pi/6 gives 1/2, and so does 5pi/6. Therefore, the two solution here would be pi/6 plus a phase shift of 2pi, and 5pi/6 plus a phase shift of 2pi:
[tex]x=\frac{\pi }{6} +2n\pi[/tex]
[tex]x=\frac{5\pi }{6} +2n\pi[/tex]
The second problem states that:
[tex]cos(u)=\frac{4}{5}[/tex]
Cosine is defined as the adjacent side of a right triangle divided by the hypotenuse of the right triangle:
[tex]cos(u)=adjacent/hypotenuse[/tex]
After drawing a triangle, the adjacent side is 4, and the hypotenuse is 5. But first, lets rewrite sin(2u) using the double angle identity to get:
[tex]sin(2u)=2sin(u)cos(u)[/tex]
But we know the value of cosine of 'u', it is 4/5. Therefore:
[tex]sin(2u)=2sin(u)*\frac{4}{5}[/tex]
[tex]sin(2u)=\frac{8}{5} sin(u)[/tex]
To find the sine of 'u', use the triangle you should have constructed when I defined cosine as the adjacent over the hypoptenuse. Sine is defined as the opposite over the hypotenuse. We have:
[tex]sin(u)=opposite/hypotenuse[/tex]
We have the adjacent, we have the hyppotenuse, and we want the opposite. If we find the opposite side, we can find the sin(2u). Use pythagogrean's theorem to find the opposite:
[tex]adjacent^2+opposite^2=hypotenuse^2[/tex]
[tex]4^2+opposite^2=5^2[/tex]
[tex]opposite^2=25-16[/tex]
[tex]opposite=3[/tex]
Finally, we have that:
[tex]sin(u)=\frac{3}{5}[/tex]
Or:
[tex]sin(2u)=\frac{8}{5}*\frac{3}{5} =24/25[/tex]
Hopefully you could follow along. There is a lot going on here, but since youre in pre-calc, you should be able to follow along as long as you follow my steps.

If the largest dimension of the pendant is 10 cm wide then the greatest length will be 5 cm. Then the correct option is C.

The slope of line that passes through the points (1, -6) and (-2, –8) is 2/3.
What is a linear equation?
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
y = mx + b
In which the coefficients are described as follows:
• The coefficient m is the slope of the function, representing the rate of change of the function.
• The coefficient b is the y-intercept of the function, representing the value of y when the function crosses the y-axis(x = 0).
Here the points are(1, -6) and (-2, –8) :
and it is to find the equation of line passing through these points :
Now using slope formula to find the slope of line m :
m = (y₂-y₁)/ (x₂-x₁)
m = (-8+6)/(-2-1)
m = -2/-3
m = 2/3
Therefore, the slope of line that passes through the points (1, -6) and (-2, –8) is 2/3.

Answer:
You can divided 74 by 5. 5 fits into 7 once so you subtract 5 and you are left with 2. Then bring down the 4 and you have 24. 5 fits into 24 only 4 times so you would subtract 20 from 24 and be left with 4. Then add a decimal point and a 0. Bring down the 0 and you'll have 40. 5 fits into 40 exactly 8 times so 40 - 40 = 0. The answer is 14.8
