Answer:

8 and 5/8 miles

Step-by-step explanation:

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

Answer:

4/14 is equivalent

Step-by-step explanation:

If you multiply 7 and 2 you will get 14

So since you multiply by 2 for the denominator you will have to do the same to the numerator

Answer:

D) infinite real solutions

Step-by-step explanation:

-6(5x+10) = -3(10x+20)

-30x-60 = -30x-60

simplifying:

x=x

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

Answer: D. {(0, - 4), (1, - 4), (2, 4), (3, 4), (4, - 4)}

Step-by-step explanation:

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.

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.

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

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

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
