Question 3 options:
A)
17, 19, 21, 23
B)
17, –6, –3, 0
C)
17, 13, 9, 5
D)
17, 15, 13, 11
Answer:
D)
17,15,13,11
Step-by-step explanation:
From the formula
[tex]f(n) = f(n - 1) - 2 \\ f1 = 17 \\ [/tex]
we can deduce the next three terms as follows:[tex]f(2) = f(2 - 1) - 2 \\ f(2)= f(1) - 2 \\ f(2) = 17 - 2 \\ f(2) = 15\\ [/tex][tex]f(3) = f(3 - 1) - 2 \\ f(3)= f(2) - 2 \\ f(3) = 15 - 2 \\ f(3) = 13\\ [/tex][tex]f(4) = f(4 - 1) - 2 \\ f(4)= f(3) - 2 \\ f(4) = 13 - 2 \\ f(4) = 11\\ [/tex]Hence the sequence is; 17, 15, 13, 11,...Energy for both renewable and nonrenewable sources originally comes from

from 2001 to 2012 the sales for a local doughnut store increased by about the same percent each year. The sales, S, for year t can be modeled by, S=372,300(6/5)^t. Where t=0 corresponds to 2001. What were the sales in 2001
Using the given exponential function, it is found that the number of sales in 2001 was of 327,300.
What is the exponential function in this question?It models the number of sales S in t years after 2001, given by:
[tex]S(t) = 372300\left(\frac{6}{5}\right)^t[/tex]
2001 is year 0, hence the amount is given by S(0), that is:
[tex]S(0) = 372300\left(\frac{6}{5}\right)^0 = 372300[/tex]
The number of sales in 2001 was of 327,300.

Jerry is running a race. He knows he can run 44 feet in 3 seconds. If he maintains this rate, how many miles will he run in 1 hour?
Step-by-step explanation:
44 ft in 3 seconds
in 1 hour there are 60 minutes with 60 seconds each.
so, 1 hour = 60×60 = 3600 seconds.
in 3600 seconds there are
3600 / 3 = 1200 "packages" of 3 seconds.
so, Jerry would run
1200 × 44 = 52800 ft in 1 hour.
there are 5280 ft in 1 mile.
that means Jerry would run
52800 / 5280 = 10 miles in 1 hour.

A construction company needs to remove 10 tons of dirt from a construction site. They can remove 2/5 tons of dirt each hour. How long will take to remove the dirt?
Step-by-step explanation:
You can just divide 10 by 2/5 and you get 25 or try this
Set up proportions and cross multiply 2/5 / 1 = 10/x which you can read as : if 2/5 can be done in 1 hour then 10 tons can be done in x hours cross multiplying, you get 2x/5 = 10 and x = 25

Answer:
2/3
Explanation:
total people: 4 + 2 = 6 people
carpenters: 4 carpenters
probability = favourable outcomes/total possible outcomesprobability = 4/6 ≈ 2/3
Answer:
P (carpenter) = 2/3 or 0.67

Answer:
48pi cm squred
Step-by-step explanation:
first find area of the circle which is pi x r^2
pi x 3^2 = 9pi
Since there are two circles...
9pi x 2 = 18pi
Then find the area of the rectangle that is wrapped around the circle by finding the circumference of the circle and then multiplying that with the height of the cylinder
circumference of the circle = 2 x pi x r
2 x pi x 3 = 6pi
6pi x 5 = 30pi
Therefore the surface area is
48pi cm squred

cups
3 number of cups will be needed to marinade 4 pounds of chicken for grill.
What is Ounce?Ounce is the small unit of weight which is generally equal to the one by 16th of the pounds.
Here we have the data from the question:-
Marcy will use 6 fluid ounces of lemon-garlic marinade for every pound of chicken.
Marcy plans to grill 4 pounds of chicken.
So total marination required will be:-
Total marination =6x4=24 ounces
Now we know that the conversion:-
1 fluid Ounce = 0.125 Cup
24 fluid ounce =0.125 Cup
Hence 3 number of cups will be needed to marinade 4 pounds of chicken for grill.

Answer:
The new points to the triangle will be:
[tex]A(-6, 6)\\B(-6, 3)\\C(-8, 3)[/tex]
Step-by-step explanation:
Because the reflection point is at [tex]x = -1[/tex], all x values will subtract their distances from [tex]x = -1[/tex] to get their new values. The y values remain the same.
The starting values are:
[tex]A(4,6)\\B(4,3)\\C(6,3)[/tex]
Point [tex]A[/tex] is 5 units away from [tex]x = -1[/tex], so we'll subtract 5 from -1 to get the new x value: [tex]-1 - 5 = -6[/tex], so [tex]A(-6, 6)[/tex].
Point [tex]B[/tex] is also 5 unit away from [tex]x = -1[/tex], so we'll subtract 5 from -1 to get the new x value: [tex]-1 - 5 = -6[/tex], so [tex]B(-6, 3)[/tex].
Point [tex]C[/tex] is 7 units away from [tex]x = -1[/tex], so we'll subtract 7 from -1 to get the new x value: [tex]-1 - 7 = -8[/tex], so [tex]C(-8, 3)[/tex].

The sum of 6 and the product of 3 and d
Answer:
6 + 3d
Step-by-step explanation:
First, we can translate from English words to mathematical operations:
– Product: the result of multiplication
– Sum: the result of addition
So, we can rephrase the original sentence as “the result of adding 6 and (the result of multiplying 3 and d)”
When we multiply a constant like 3 by a variable like d, we usually write the two next to each other, which would be “3d” in this case. We can replace that last sentence in symbols with 6 + 3d
