Hank draws a line with a zero slope through the points
(–2, 4) and (3, b). Which value of b could represent Hank’s second point?
–3
–1
4
9
Answer:
b=4
Step-by-step explanation:
Since the line has a slope of zero, it's a horizontal line. A horizontal line so have the same y axis bc it passes through the y axis. So in this case the coordinate point is (-2,4) and it has a zero slope so you can assume that b= 4 since it has a zero slope.
Answer: C=4

an open tank has tge shape of circular cone. the tank is 8feet across the top and 6 feet high. watwr is pumped through the buttom of the tank. how much work is done to fill the tank from a depth of 4 feet to a depth of 6 feet? water weighs 62.4 pounds per cubic foot
Answer:
[tex]W=22652.98ft-lb[/tex]
Step-by-step explanation:
We are given that
Height of tank=6feet
Diameter of tank=8 feet
Radius of cone,r=d/2=8/2=4 feet
Let a layer of thickness dy at distance yr from the bottom at origin
y=6 feet
Using similar triangle property
[tex]\frac{r}{y}=\frac{4}{6}=\frac{2}{3}[/tex]
[tex]r=\frac{2}{3}y[/tex]
Weight of water=62.4 pounds per cubic foot
Now,
Weight of layer=[tex]62.4\times \pi r^2 h=62.4(\frac{4}{9}\pi y^2 dy[/tex]
Now, work done to fill the tank from a depth of 4 feet to a depth of 6 feet is given by
[tex]W=\int_{a}^{b}62.4\times \frac{4}{9}\pi y^2(y) dy=\int_{4}^{6}62.4\times \frac{4}{9}\pi y^3 dy[/tex]
[tex]W=\frac{62.4\times 4\pi}{9}[\frac{y^4}{4}]^{6}_{4}[/tex]
[tex]W=\frac{249.6\pi}{36}(6^4-4^4)[/tex]
[tex]W=22652.98ft-lb[/tex]

Answer:
Kindly check explanation
Step-by-step explanation:
Verbal statement and associated probability:
P = 0 ; This event is Impossible event, it will never occur. It is the least value of probability an event can take.
P = 1 ; This event is certain, it will occur on every trial. It is the highest value of probability an event can have.
P = 0.6 ; very likely event, but will occur once in a while in a long sequence of trials ; very likely signifies a probability above average (0.5) though will not always occur.
P = 0.45 ; This event will occur slightly less often than not; as the probability value slightly falls below the average standardized probability value (0.5)

A deal is a deal, so here is a good one, let's see who gets it right I had $5.00. My mom gives me $10.00, My dad gave me $30.00. My aunt and uncle give $100.00. I had another $5.00. How much money did I have?
Answer:150.00$
Step-by-step explanation:
The total amount that the person will have is $150.00
Amount that the person had = $5.00 + $5.00 = $10.00Amount given by mum = $10.00Amount given by dad = $30.00Amount given by aunt and uncle = $100.00The total amount that the person had will be the addition of all the amount that he already had and those that he was given. This will be calculated thus:
$10.00 + $10.00 + $30.00 + $100.00 = $150.00
Therefore, the total amount that the person will have is $150.00

Greta can bike 6 miles in 30 minutes. At that rate, how many miles can she bike in 45 minutes?
Answer: 9 miles
Step-by-step explanation:30 divided by 6 is 5. So the was biking 1 mile every 5 minutes. 45 divided by 5 is 9.
Feet up a ratio for miles over time:
6/30 = x/45
Cross multiply:
30x = 270
Divide both sides by 30:
X = 270/30
X = 9 miles

The entrepreneurship club is ordering potted plants for
all 36 of its sponsors. One store charges $8.50 for each
plant plus a delivery fee of $20.
The equation 320 = x + 7.50(36) represents the cost
of ordering potted plants at a second store.
What does the x represent in this situation?
The cost for each potted plant at the second store
The delivery fee at the second store
The total cost of ordering potted plants at the second store
The number of sponsors of the entrepreneurship club
Yes
Answer:
The delivery fee at the second store
Step-by-step explanation:
The x represents the delivery charge.
The cost for each potted plant at the second store is $7.50.
The delivery fee at the second store is $50.
The total cost of ordering potted plants at the second store is $270.
The number of sponsors of the entrepreneurship club is 36.
Given,
The entrepreneurship club is ordering potted plants for all 36 of its sponsors.
One store charges $8.50 for each plant plus a delivery fee of $20.
The equation 320 = x + 7.50(36) represents the cost of ordering potted
plants at a second store.
We need to find:
- what does the x represents
- the cost for each potted plant at the second store
- the delivery fee at the second store
- the total cost of ordering potted plants at the second store
- the number of sponsors of the entrepreneurship club
How do we represent a total cost with different charges and a number of items?If the number of items = M
Cost of each item = $N
Charges = P
Then the total cost can be represented by:
= M x $N + P
The charges are separated since it's an individual charges.
The exclusive total cost for the items is:
= Number of items x Cost of each item.
We have,
Number of sponsors = 36
One store:
Cost of each plant = $8.50
Delivery fee = $20
Second store:
320 = x + 7.50(36)
This equation represents the cost of ordering plotted plants from the second store.
Here,
x = delivery charges
Cost of each plotted plant = $7.50
The delivery fee at the second store:
320 = x + 7.50(36)
320 = x + 270
x = 320 - 270
x = $50
The total cost of ordering potted plants at the second store:
= 7.50 x 36
= $270
The number of sponsors of the entrepreneurship club:
= 36
Thus,
The x represents the delivery charge.
The cost for each potted plant at the second store is $7.50.
The delivery fee at the second store is $50.
The total cost of ordering potted plants at the second store is $270.
The number of sponsors of the entrepreneurship club is 36.

There is no options to choose from and I need to find slope help due today
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
To find the slope we need two points.
A = ( -2 , 5 ) & B = ( 0 , 2 ) & C = ( 2 , -1 )
I choose A and B .
_________________________________
We have following equation to find the slope using two points.
[tex]slope= \frac{y(B) - y(A)}{x(B) - x(A)} \\ [/tex]
Now just need to put the coordinates in the above equation.
Let's do it...
[tex]slope = \frac{2 - 5}{0 - ( - 2)} \\ [/tex]
[tex]slope = \frac{ - 3}{2} \\ [/tex]
[tex]slope = - \frac{3}{2} \\ [/tex]
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
I suggest to find the slope using A , C
and B , C to can understand exactly what did I do buddy.
Good luck ♥️♥️♥️♥️♥️
