Answer:
0m
Step-by-step explanation:
Before the ball is thrown, it is at the ground level. At the ground level, the height is zero. Substitute h = 0 into the equation;
h(x)=-x^2+10x-16
0=-x^2+10x-16
x^2-10x+16 = 0
Factorize
x^2-8x-2x+16 = 0
x(x-8) - 2 (x-8) = 0
x-2 = 0 and x - 8 = 0
x = 2 and 8
At x = 2
h(2) = -2^2 + 10(2) - 16
h(2) = -4 + 4
h(2) = 0
Hence the height of the ball at the time it is thrown is 0m

A label is twice as long as it is wide. If the length of the label is 10 cm, find the
area of the label.
O 20 square centimeters
O 50 square centimeters
O 60 square centimeters
O 70 square centimeters
Answer:
50 square centimeters
Step-by-step explanation:
Long means length, and we know the length of the label, 10 centimeters. That means the width is half of 10 centimeters, or 5 centimeters. Now, we multiply 10 and 5 to get 50. That means the area of the label is 50 square centimeters
Daryl measures the angle of elevation to be 62 degrees. Frances measures the angle of elevation to be 54 degrees. if the two enthusiasts are 28m apart, how far off the ground is the helicopter.
Answer:
The helicopter is 27.38 m far off the ground
Step-by-step explanation:
The drawing shown in the image below has all the measures and variables needed to solve the problem.
We need to find R, the height of the helicopter. We'll use the law of sines to find the length of side a.
[tex]\displaystyle \frac{28}{\sin X}=\frac{a}{\sin 54^\circ}[/tex]
The angle X is the measure needed to complete 180°:
X = 180° - 54° - 62° = 64°
Solving for a:
[tex]\displaystyle a=\frac{28}{\sin 64^\circ}\cdot \sin 54^\circ[/tex]
Calculating:
a = 31.11 m
Now using the sine ratio in the right triangle to the left side:
[tex]\displaystyle \sin 62^\circ=\frac{R}{a}[/tex]
Solving for R:
[tex]R=a\sin 62^\circ[/tex]
R=31.11*0.88
R = 27.38 m
The helicopter is 27.38 m far off the ground

Answer:
Step-by-step explanation:
From the given information:
We learned that it is possible that all entities can be in one of two states i.e. 0 or 1. Thus, all 5 entities can either be 0 or 1 (2 states).
∴
Number of outcomes = 2 × 2 × 2 × 2 × 2
= 2⁵
= 32
b)
All the outcomes of W = {(1, 1, x₃, x₄, x₅) (x₁, x₂, 1, 1, x₅) (1, x₂, 1, x₄, 1)}

Sarah has three more than four times the money that Jessica has. Together they have $72. How
much does each person have?
Answer:
Jessica has x amount of dollars.
Sarah has 4x + 3
Together they have $72
We can combine Jessica and Sara's money to equal $72.
x + (4x + 3) = 72
Combime like terms
5x + 3 = 72
Subtract 3 from both sides to isolate the variable.
5x = 69
Divide both sides by 5
x = 69/5 or 13 4/5 or 13.80
Jessica has $13.80 and
Sarah has 4(13.80) + 3
55.20 + 3 = 58.20

Using the equation ŷ = 2.6 − 3.1x, what is the predicted value if x is 4.3?
Select one:
a. −10.73
b. 10.73
c. 15.93
d. −15.93
e. 0.54
Work Shown:
Plug x = 4.3 into the equation given
ŷ = 2.6 − 3.1x
ŷ = 2.6 − 3.1(4.3)
ŷ = 2.6 − 13.33
ŷ = -10.73
Note: The symbol ŷ is read as "y hat". It's used to estimate the y value when it comes to regression equations.
