Answer:

Joe paid $2,940 in interest after six years.

Step-by-step explanation:

Since Joe borrowed $7000 from the bank at a rate of 7% interest <em>per year. </em>We need to find 7% of 7,000.

7,000 x 0.07 = 490

Since we need to find out how much interest Joe paid after six years, we need to multiply 490 by 6.

490 x 6 = 2,940

Therefore, Joe paid $2,940 in interest after six years.

Hope this helps! :D

F(x) =?. Vertex is (2,-4) the other given point is (1,-2)
dalvyx [7]
Given the vertex, (2, -4) as the minimum point, and that it is an upward-facing parabola that passes point (1, -2):

We could substitute these values into the vertex form of the quadratic function,

f(x) = a(x - h)^2 + k

where:

(h,k) is the vertex

The axis of symmetry is the vertical line x = 2

The value of “a” determines whether the graph opens up or down, and makes the parent function wider or narrower.

The value of “h” determines how far left or right the parent function is translated.

The value of “k” determines how far up or down the parent function is translated.


Now that we’ve established these definitions, we can substitute the given values into the vertex form:

f(x) = a(x - 2)^2 - 4

In order to determine the value of “a”, we must substitute the values of the other given point, (1, -2) into the equation:

f(x) = a(x - 2)^2 - 4

-2 = a(1 - 2)^2 - 4

-2 = a(-1)^2 - 4
-2 = a - 4

Add 4 to both sides to solve for “a”

-2 + 4 = a - 4 + 4
2 = a

Now that we have the value of a = 2, we can establish our quadratic function in vertex form:

f(x) = 2(x - 2)^2 - 4


I’m also including a screenshot of the graph of the function we came up with.

Ziv's taxicab ride cost $33. He left a 15% tip.
sergiy2304 [10]

Answer:

Step-by-step explanation:

1. Find 15% of $33 to find the tip.

Find 1%  of $33 (move the decimal over 2 places to the left.        $0.33

2. Multiply the 1% tip by 15%

       33 * 15 =  $4.95  

3. Add $33 and $4.95

          4.95 + 33.00 = $37.95 total

A cone has a volume of 5 cubic inches. What is the volume of a cylinder that the cone fits exactly inside of?
DENIUS [597]
The answer is 15 in³.

The volume of the cone is:
V_1= \pi r_1 ^{2}  \frac{h_1}{3} = \frac{ \pi  r_1^{2} h_1}{3}
where:
V₁ - the volume of the cone
r₁ - the radius of the cone
h₁ - the height of the cone

The volume of the cylinder is:
V_2= \pi  r_2h_2^{2}
where:
V₂ - the volume of the cone
r₂ - the radius of the cone
h₂ - the height of the cone

Since <span>the cone fits exactly inside of the cylinder, they have the same radius and the height:
r</span>₁ = r₂
h₁ = h₂

Also:
V₁ = 5

Now, let's write two volume formulas together:
V_1= \frac{ \pi r^{2} h}{3}
<span>V_2= \pi rh^{2}</span>

We can include V₂ into V₁:
V_1= \frac{V_2}{3}

⇒ V_2=3*V_1
V_2=3*5 in^{3}
V_2=15 in^{3}
