Answer:
Exponential
Step-by-step explanation:
Exponential describes a very rapid increase. An exponential rise in the number of first graders with head lice might be a result of all the hat sharing that's gone on lately.
Exponential is also a mathematical term, meaning "involving an exponent." When you raise a number to the tenth power, for example, that's an exponential increase in that number. When your next door neighbor describes the exponential growth of her rose bushes or the exponential increase in members of her book group, she means that there's been a sharp, fast expansion of both things.

find the slope of the line that passes through (8,10) and (5,5)
Answer:
5/3
Step-by-step explanation:
The slope is the rise over run or the change in y over the change in x. One way to find the slope is through the formula, which is [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]. To use this simply plug in the two points. In this case, the expression would be [tex]\frac{10-5}{8-5}[/tex]. This simplifies down to 5/3.

Answer:
Slope = -3.5
Step-by-step explanation:
Find the slope using any two given pair of values. Let's use (6, -21) and (12, -42).
Slope = ∆y/∆x
Slope = (-42 -(-21)) / (12 - 6)
Slope = -21/6
Slope = -3.5

Show your work or strategy:
When does the car reach its minimum speed? _________________
What is the minimum speed? _________________________
Answer:
At t=2s the car reach its minimum speed
Minimum speed=8m/s
Step-by-step explanation:
We are given that velocity of car
[tex]v(t)=t^2-4t+12[/tex]
0<t<4
Differentiate w.r.t t
[tex]v'(t)=2t-4[/tex]
[tex]v'(t)=0[/tex]
[tex]2t-4=0[/tex]
[tex]2t=4[/tex]
[tex]t=2[/tex]
[tex]v''(t)=2>0[/tex]
The velocity is minimum at t=2 s
Substitute t=2
[tex]v(2)=2^2-4(2)+12[/tex]
[tex]v(2)=8m/s[/tex]
Hence, the speed of car is minimum at t=2 se and minimum speed of car=8m/s

a submarine travels at an elevation of -75 3/4 ft relative to sea level then its elevation changes by - 16 3/8 what is the new elevation of the submarine
Answer:
[tex]New = -92\frac{1}{8}[/tex]
Step-by-step explanation:
Given:
[tex]x = -75\frac{3}{4}[/tex] --- Position
[tex]\triangle x = -16\frac{3}{8}[/tex] --- Change
Required
Find the new position
The new position is calculated as:
[tex]New = x + \triangle x[/tex]
[tex]New = -75\frac{3}{4} - 16\frac{3}{8}[/tex]
[tex]New = -75.75 - 16.375[/tex]
[tex]New = -92.125[/tex]
[tex]New = -92\frac{125}{1000}[/tex]

1. The managers at the hunting store usually determine their prices by using a markup of 11
percent. If they purchased camo pants for $45 each, what will be the price for their customers?
2. The fishing store manager buys flies from a wholesale company for $2.50 apiece. If he prices
each fly for the customers at $3.75, what is the markup percentage?
0.45+100x 11=4.95+45=49.95
50-1008 2.50 = 1.25=50%,
3. The pet store managers purchase dog food from a wholesale company for $3.75 a bag. If
they sell the dog food to the customers for $5.00 a bag, what is the markup percentage they are
using?
Answer:
$49.95 ; 50% ; 33.33%
Step-by-step explanation:
1.)
Markup % = 11%
Purchase price = $45
Selling price will be :
(100 + 11)% * $45
1.11 * $45 = $49.95
2.)
Purchase price = $2.50
Selling price = $3.75
Markup % :
Profit / purchase price * 100%
[(3.75 - 2.50) / 2.50)] * 100%
1.25 / 2.50 * 100%
0.5 * 100% = 50%
3.)
Purchase price = $3.75
Selling price = $5.00
Markup % :
Profit / purchase price * 100%
[(5.00 - 3.75) / 3.75)] * 100%
1.25 / 3.75 * 100%
0.3333 * 100% = 33.33%
15x+2y=4000........(1)
10x=4y....(2)
find value of X & Y
Answer:
x = 400
y = 1000
Step-by-step explanation:
Step 1
mult by the first equation by 2
15x + 2y = 4000 ....... x 2
30x + 4y = 8000
the second equation is
10x = 4y
=
10x - 4y =0
then subtract the second equation from the first one
30x + 4y = 8000
- (minus)
10x - 4y = 0
the you will get
20x = 8000
x = 8000/20 = 400
then you will substitute value of x in any the give equation to work out the value of y

What is the area of the shaded region?
Answer:
approx 54.94
Step-by-step explanation:
area of square is 16^2=256
area of circle is pi(8^2)= approx 201.06
256-201.06=54.94
Answer:
[tex] 55.04 \: {cm}^{2} [/tex]
Step-by-step explanation:
Side length of square = 16 cm
Diameter of circle = Side of square = 16 cm
Radius of circle = 16/2 = 8 cm.
Area of the shaded region =
Area of square - Area of circle
[tex] = {16}^{2} - \pi\times {8}^{2} \\ \\ = 256 - 3.14 \times 64 \\ \\ = 256 - 200.96 \\ \\ = 55.04 \: {cm}^{2} [/tex]
(7.2 x ten to the third) - (2.2 x ten to the fifth)
Answer:
-212800
Step-by-step explanation:
7.2 × 10³ = 7.2 × 1000 = 7200
2.2 × 10 to the power 5 = 2.2 × 100000 = 220000
7200 - 220000 = -212800
KFC sells whole chicken dinners for 12 and half chicken dinners for 8. Yesterday it sold a total of 400 dinners and took in 4200. How many of each size dinner were sold? What were the cedi sales of each size dinner?
Answer:
150 half chicken and 250 full chicken
Step-by-step explanation:
Represent whole chicken with w and half chicken with h.
So, we have:
[tex]Total = 400[/tex]
Which implies that:
[tex]w + h = 400[/tex]
Also:
[tex]Amount =\$4200[/tex]
Which implies that:
[tex]12w + 8h = 4200[/tex]
So, we are to solve for h and w from:
[tex]w + h = 400[/tex]
[tex]12w + 8h = 4200[/tex]
Make h the subject in the first equation
[tex]h = 400 - w[/tex]
Substitute 400 - w for h in the second equation
[tex]12w + 8(400 - w) = 4200[/tex]
[tex]12w -8w + 3200 = 4200[/tex]
[tex]12w -8w =- 3200 + 4200[/tex]
[tex]4w =1000[/tex]
[tex]w = 250[/tex]
Recall that:
[tex]h = 400 - w[/tex]
[tex]h = 400 - 250[/tex]
[tex]h =150[/tex]
