f(x)=-(x-3)²+1 determine the vertex

Answers

(3,1) would be the answer

Answer:

vertex = (3, 1 )

Step-by-step explanation:

The equation of a parabola in vertex form is

f(x) = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

f(x) = (x - 3)² + 1 ← is in vertex form

with vertex (h, k ) = (3, 1 )

A rectangular prism has the following dimensions. The base has sides that are 3 cm. and 5 cm. and the height is 9 cm. How many squares with 1 cm edges can cover the entire surface area of the prism completely with no overlaps?

Answers

Answer:

174 squares

Step-by-step explanation:

I would start by finding the surface area of the rectangular prism. You can use 2(wl+hl+hw).

2(wl+hl+hw)

2(3*5+9*5+9*3)

2(15+45+27)

2(87)

174 cm^2

The area of squares 1 cm edges would be 1 because 1*1=1, so you could find how many of them would fit on the surface area by dividing 174 by 1, which equals 174.

A concert is $250 per ticket and the cost of parking is free. This is expressed
as p(x) = 250x. If the profit is $6,000 how many tickets were sold?

Answers

Answer:

24

Step-by-step explanation:

p(x) = 250x

6000 = 250x

x = 24

Answer:

24 tickets

Step-by-step explanation:

p(x) = 250x

Substitute 6,000 for p(x)

6,000 = 250x

Divide each side of the equation by 250

24 = x

1. 3(x + 4) = 3(x - 5)
(could you please show work)

Answers

Use distributive property on both sides

3(x+4)=3(x-5)

3(x)+3(4)=3(x)-3(5)

3x+12=3x-15

Subtract 3x from both sides

12=15.

So because this is a false statement the equation has no solution. So your answer is no solution. Hope this helps!!!

What is the equation of a line perpendicular to y=-2/5X-1 that passes through (2,-8)

Answers

Answer:

[tex]y=\frac{5}{2}x-13[/tex]

Step-by-step explanation:

Given the equation

[tex]y=-\frac{2}{5}x-1[/tex]

comparing the equation with the slope-intercept form[tex]y=mx+b[/tex]

Here,

m is the slope b is the intercept

so the slope of the line is m = -2/5

As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line,

so  the slope of the perpendicular line will be: 5/2

Therefore, the point-slope form of the equation of the perpendicular line that goes through (2,-8) is:

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-\left(-8\right)=\frac{5}{2}\left(x-2\right)[/tex]

[tex]y+8=\frac{5}{2}\left(x-2\right)[/tex]

subtract 8 from both sides

[tex]y+8-8=\frac{5}{2}\left(x-2\right)-8[/tex]

[tex]y=\frac{5}{2}x-13[/tex]

EASY!!!! Answer this question correctly

Answers

Answer:

1st answer choice- You do not have enough jars because 20 jars will only hold 35 cups of applesauce.

Step-by-step explanation:

So 1.75 cups of applesauce fits in a jar. You have 20 jars so you multiply the cups of applesauce that can fit in the jar by how many jars you have. It will look like this: 1.75x20=? Now you multiply them and you get 35 which is how many cups of applesauce 20 jars will hold. You will have 5 cups of applesauce left over that cannot be transformed into a jar.
