what's the slope between (5,-2) and (-7,22)
Answer: The answer is: -2
Step-by-step explanation:
Here, suppose
(5,-2)=(x1, y1)
(-7,22)=(x2, y2)
Now, use the slope equation to find slope(m).
y2-y1=m(x2-x1)
or,m=y2-y1/x2-x1
After this, just substitute the values from above.
A right circular cylinder is changing shape. The radius is decreasing at the rate of 2 inches/sec while it's height is increasing at the rate of 5 inches/sec. When the radius is 4 inches and the height is 6 inches, how fast is the volume changing? Round your answer to three decimal places
The volume of the right circular cylinder is changing at a rate of approximately 50.265 cubic inches per second.
Given that a right circular cylinder is changing shape.
The radius is decreasing at the rate of 2 inches/sec
dr/dt = -2 inches
The radius is increasing at the rate of 2 inches/sec
dh/dt=5 inches
We have to find dv/dt when r is 4 inches and h is 6 inches.
Volume=πr²h
Differentiate with respect to 't' to find the change of volume:
[tex]\frac{dV}{dt}=\pi(2rh\frac{dr}{dt}+r^2\frac{dh}{dt})[/tex]
Plug in the values:
[tex]\frac{dV}{dt}=3.14(2(4)(-2)(6) + 16(5))[/tex]
[tex]=3.14(-96+80)[/tex]
[tex]=3.14(-16)[/tex]
[tex]=-50.265[/tex] inch³/sec.
Hence, the volume change is -50.265 inch³/sec.

A map has the scale 0.75 of an inch equals 220 miles. The distance from Springfield to Glenview is 6 inches. How many actual miles separate Springfield from Glenview?
Answer:
1,760 actual miles separate Springfield from Glenview.
Step-by-step explanation:
Scaling
Objects can be represented in a reduced or augmented size by using scaling which is basically multiplying or dividing real dimensions by a constant factor. We use scaling when representing geographic locations on a map.
The map has the scale:
0.75 inch => 220 miles
This gives us the scaling factor as 220/0.75. There is no need to divide.
We are given the distance from Springfield to Glenview is 6 inches on the map. The actual distance is
6*220/0.75 = 1,760
1,760 actual miles separate Springfield from Glenview.

Im kinda confused on this too
Step-by-step explanation:
Debbie launched a toy rocket off a hill next to Lake Lakewood. The height h of the rocket in feet above the surface of the lake can be modeled by h = 340 + 100 t − 16 t 2 h=340+100t−16t 2 , where t is the time in seconds after the launch
Answer:
t = 8.69 s
Step-by-step explanation:
The height h of the rocket in feet above the surface of the lake can be modeled by :
[tex]h=340+100t-16t^2[/tex]
Let we need to find the time to reach the ground. When it reach the ground, h = 0
[tex]340+100t-16t^2=0[/tex]
We need to find the value of t.
t = 8.69 s and -2.45 s
Neglecting negative value,
t = 8.69 s
Hence, it will take 8.69 s to reach the ground.

Domain and Range both are real numbers for all odd-degree polynomial functions.
Writing in an Interval Form, note that we use the least value in the left and the most value in the right.
From [a,b], [a,b), (a,b] or (a,b) | a must be less than b.
Therefore, the D choice is wrong in Interval part (However, right in range and domain but just for interval order.)
So the answer is C.

X = 5
Step-by-step explanation:
At a store, a hat has a regular price of x dollars. During a sale, the price of the hat is discounted by 20%. The expression 0.8x describes the discounted price, in dollars, of the hat. Which expression also describes the discounted price, in dollars, of the hat?
Answer: D) x - 0.2x
Step-by-step explanation:
The hat has a regular price of x dollars.
This price is reduced by 20% so the relevant expression for the discount is; 20% * x or; 0.2x
The discounted price will be the price of the hat less the discount which means the formula will be;
= Price - discount
= x - 0.2x
