Answer:
Let y be the total earning x be the hours workedand 20 be the hourly rate y=20xAngle X and Angle Y are complementary angles. Angle X is eight times larger than Angle Y. What are the
measures of Angle X and Angle Y?
Answer:
If you know that Angle X and Angle Y are complementary angles, X+Y = 90
Then we translate the sentence "angle x is 8 times larger than angle Y" into mathematical terms. is means equal, and 8 times means multiplication. This gives us our second equation
X = 8Y
We then use the property of substitution to combine the equations into a solvable system. if X = 8Y and X + Y = 90, we can say that 8Y + Y = 90.
combining like terms, we have 9Y = 90. Y then equals 10.
We then substitute back into the original X = 8Y to get X = 8*10. X = 80.
The final answer is X = 80 degrees and Y equals 10 degrees

You drop a ball from a height of 98 feet. At the same time, your friend throws a ball upward. The polynomials represent the heights (in feet) of the balls after t seconds. At what time do the balls reach the same height?
Answer: The polynomial is 92 - 46t
92,92,-46,46
Step-by-step explanation:
The polynomial represent the heights (in feet) of the balls after t seconds is : -46t+92
What is a polynomial?They are mathematical expressions involving variables raised with non negative integers and coefficients(constants who are in multiplication with those variables) and constants with only operations of addition, subtraction, multiplication and non negative exponentiation of variables involved.
The motion of both balls is a free-fall motion which means that the ball is acted upon the force of gravity only.
Therefore, the motion of the ball is a uniformly accelerated motion, with constant acceleration equal to the acceleration of gravity:
g = 32 ft / sec sq.
The ball which is thrown upward from the ground instead is fired with an initial vertical velocity , and its starting height is zero, so its position at time t is given as;
h(t) = ut - 1/2 gt²
Therefore, the polynomial that represents the distance between the two balls is -46t+92

C.
{(-4,9), (- 3, 1), (- 2, 3), (- 2, 12), (0, 6) }
D.
{(0, - 4), (1, - 4), (2, 4), (3, 4), (4, - 4)}
О O
Answer: D. {(0, - 4), (1, - 4), (2, 4), (3, 4), (4, - 4)}
Step-by-step explanation:
A relation R is said to be a function if for each input value there exists only one unique output value.In (x,y) , x= Input value , y= output value.
A. {(-1, - 4), (-1,0), (- 1,5), (- 1, 7), (-1,9)}
Here, -1 has two output values -4 and 0.
So it is not a function.
B. (-2, - 4), (-1,7), (1, - 1), (1, 1), (3,9)}
Here, 1 has two output values -1 and 1.
So it is not a function.
C. {(-4,9), (- 3, 1), (- 2, 3), (- 2, 12), (0, 6) }
Here, -2 has two output values 3 and 12.
So it is not a function.
D. {(0, - 4), (1, - 4), (2, 4), (3, 4), (4, - 4)}
here, each input value has an unique output value.
Hence, D. option is correct.

Answer:
B and C
(I'm not sure if b and e are supposed to be the same though) if they are then, b, c, and e
Answer:
The correct options are Option A and Option D
Step-by-step explanation:
Mark wants to find the area of a circle with a diameter of 6 cm.
We need to find the expressions can he use to find the area of the circle in square centimetres?
The formula used to find area of circle is: [tex]Area=\pi \:r^2[/tex]
We are given Diameter = 6 cm
Radius = Diameter/2 = 6/2 = 3 cm
We get radius = 3cm
Now, putting values and finding area
[tex]Area=\pi \:r^2\\Area=\pi \:(3)^2\\Area=3^2\:\pi[/tex]
We can also write it as:
[tex]Area=3*3*\:\pi[/tex]
So, correct options are Option A and Option D
