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

Angle 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

What is the equation of a line that is perpendicular to a line with a slope of 2 and passes
through the point (-2, 0)?
To find the equation of a perpendicular line, you first need to find the negative reciprocal of the slope given. The slope is -1/3, so the slope of the perpendicular line will be 3
Now we just need to find the y intercept using the point (3, 2) and you can plug the coordinates in and then solve for b. Let's see what that looks like.
y=3x+b
2=3*(3)+b
2=9+b
-7=b So now we know the y-intercept and slope. We just put them together now
y=3x-7
A circle is represented by the equation below: (x + 8)2 + (y − 3)2 = 100 Which statement is true?
The circle is centered at (−8, 3) and has a radius of 20.
The circle is centered at (8, −3) and has a diameter of 20.
The circle is centered at (8, −3) and has a radius of 20.
The circle is centered at (−8, 3) and has a diameter of 20.
Answer:
D) The circle is centred at (-8,3) and has a diameter 20
Step-by-step explanation:
Explanation:-
Given that the circle
( x + 8)² +( y-3)² = 100
⇒ ( x + 8)² +( y-3)² = 10²
Standard form of the circle ( x-h)² +(y-k)² = r²
Centre of the circle (h , k) = (-8 , 3)
Radius of the circle r = 10
Diameter of the circle 'd' = 2r = 2(10) =20
Final answer:-
The circle is centred at (-8,3) and has a diameter 20
Answer:
The circle is centered at (−8, 3) and has a diameter of 20.

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.
The house was bought for $125,000 in 1990, the overage rate is 7.85%, what year will the purchase of the house be worth 3 times the purchase price?
Answer: 2005
Step-by-step explanation:
Exponential function to determine the value of item after t years,
[tex]f(x)=A(1+r)^t[/tex] , where r= rate of growth, A=Initial value.
As per given , A = 7.85% = 0.0785
A = $125,000
Substitute all values in function, we get
[tex]f(x)=125000(1+0.785)^t[/tex]
When f(x)= 3A , then
[tex]3A=A(1.0785)^t\\\\\Rightarrow\ 3=(1.0785)^t[/tex]
Taking tog on both sides , we get
[tex]\ln 3=t\ln 1.0785\\\\\Rightarrow\ t=\dfrac{\ln 3}{\ln 1.0785}\\\\\Rightarrow t=\dfrac{1.09861228867}{0.0755711868471}\approx15[/tex]
The year will be 1990+15= 2005
Hence, the required year = 2005
