Slope of tangent = -4
Point slope form:

Or you can construct the upper half of the circle in y=(17-x^2)^(1/2) and differentiate it to get the slope then use point slope form again

Use completing the square to rewrite the given function in vertex form. Determine whether the vertex is a maximum or minimum
value. Select the TWO correct answers.
y = x2 + 4x - 10
-
A)
The vertex form is y = (x - 6)2 + 2.
B)
The vertex form is y= 4x + 2)2 - 10.
C)
The vertex form is y = -(x - 2)2 - 6.
D)
The vertex is a minimum value at point (-6,2).
E)
The vertex is a maximum value at point (2.-6).

Answers

Answer:

Step-by-step explanation:

The equation as written doesn’t work. Are you sure it is y = x² + 4x - 10, and not

y = -x² + 4x - 10 ?

y = -(x² - 4x) - 10

y = -(x² - 4x + 2²) + 2² - 10

y = -(x-2)² - 6

the vertex is a maximum at (2,-6)

a₂₀ = 69

Step-by-step explanation:

The nth term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 12 and d = 15 - 12 = 3 , then

what is the volume of the rectangular prism

Answers

It is all the numbers multiplied together. 135

Answer:

[tex]\Huge\boxed{D.135 cm^3}[/tex]

Step-by-step explanation:

Hello There!

We can find the volume of the figure by using the formula for volume of a rectangular prism

[tex]V=lwh[/tex]

where l = length, w = width and h = height

we are given all of the dimensions so all we have to do is plug in the values

V = 3 x 9 x 5

3x9=27

27x5=135

so the volume of the rectangular prism is 135 cm³

Find the area of the parallelogram.

Answers

Answer:

36 ft^2

Step-by-step explanation:

I) Find dimensions:

The base is 9 feet, and the height is 4 feet.

(Remember, 6 ft is not the height because that is the height of the parallelogram's parallel sides.)

II) Find area:

Area = base x height

A = B x H

36 = 9 x 4

III) Find unit:

Make sure to add the unit, it is ft^2 or ft² since this figure is three-dimensional and measured in feet.

James is participating in a 3-mile walk to raise money for a charity. He has received $300 in fixed pledges and raises $13 extra for every mile he walks. Use a point-slope equation to find the amount he will raise if he completes the walk.

Answers

Answer: $339

Step-by-step explanation:

Given

The total length of the journey is 10 miles

fixed pledges are $300

variable pledges are $13 per mile

Point slope equation form is

[tex]\Rightarrow y=mx+c[/tex]

Here the total charge corresponds to y and miles walked corresponds to x

So, we can write

[tex]T=13\times m+300[/tex]

where,

[tex]T=\text{Total charge}\\m=\text{miles walked}[/tex]

for 3 miles distance

[tex]\Rightarrow T=3\times 13+300=\$339[/tex]

What is fraction?

An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.

Given:

It takes an old printer 8 hours to print all the pictures for the yearbook.

A modern printer can do the same job in 5 hours.

If both work together,

it will take,

x(1/8 + 1/5) = 1

x(8 + 5)/40 = 1

8x + 5x = 40

x = 40/13

x = 3.07

x = approximately 3.1 hours.

Therefore, the work will be done in 40/13 hours.
