Answer:

y = -15x + 250

Step-by-step explanation:

Slope: I see two distinct points: <em>(14, 40) and (10, 100)</em>.

Using the slope equation, I get: <em>(100 - 40)/(10 - 14) = </em><em>-15</em>.

The slope is -15, so in a point-slope formula, it will go before the x.

Y-intercept: on the graph, when x = 0, y is 250. That goes after the x +.

A fishbowl shaped like a sphere is filled with water. The fishbowl has a diameter of 16 inches. Which measurement is closet to t
rjkz [21]

Answer:

A) 2144.66 in³

Step-by-step explanation:

A fishbowl shaped like a sphere is filled with water. The fishbowl has a diameter of 16 inches. Which measurement is closet to the volume of water in the fishbowl in cubic inches?

Volume of a sphere = 4/3πr³

Diameter = 16 in

Radius = Diameter/2 = 16 in/2 = 8 in

Volume of a Sphere = 4/3 × π × 8³

= 2144.66 cubic Inches

Option A.is correct

Hey can you please help me posted picture of question
KengaRu [80]
The Vertex of the parabola is V=(-5,-2)=(h,k)→h=-5, k=-2
This is a vertical parabola, then its equation has the form:
y=a(x-h)^2+k
Relacing h=-5 and k=-2
y=a(x-(-5))^2+(-2)
y=a(x+5)^2-2

When the x-value is -4, the y-value is 2. What is the coefficient of the squared expression in the parabola's equation:
a=?
x=-4, y=2→2=a(-4+5)^2-2
2=a(1)^2-2
2=a(1)-2
2=a-2
2+2=a-2+2
4=a
a=4

Answer: The coefficient of the squared expression in the parabola's equation is 4

What output is twice the sum of the input 3 and 4
Andreas93 [3]

Answer:

Required output = 14

Step-by-step explanation:

Sum of the input 3 and 4 = 3 + 4

Twice the sum means two times.

So, to find twice the sum of the input 3 and 4, we need to multiply the sum by 2.

2(3 + 4)

Perform the addition inside the parentheses.

2(3 + 4) = 2(7)

Now, multiply.

2(3 + 4) = 14

Hence, required output = 14
