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]

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)

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.

Which slope is 1/4
So the
(slope of tangent) x (1/4) = -1
Slope of tangent = -4
Point slope form:
(y-1)/(x-4)=-4

y=-4x+17
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
