Step-by-step explanation:
If a=-3 what is 3a squared
Answer: 27
====================================================
Work Shown:
a = -3
a^2 = (-3)^2 .... squaring both sides
a^2 = 9
3a^2 = 3*9 .... multiply both sides by 3
3a^2 = 27
------------------
Or you could do it this way
3a^2 = 3(-3)^2 ... replace 'a' with -3
3a^2 = 3(9)
3a^2 = 27
The temperature, HH, in degrees Celsius, of a cup of coffee placed on the kitchen counter is given by H=f(t)H=f(t), where tt is in minutes since the coffee was put on the counter. (a) Is f′(t)f′(t) positive or negative? negative (Be sure that you are able to give a reason for your answer.) (b) What are the units of f′(20)f′(20)? help (units) Suppose that |f′(20)|=1.5|f′(20)|=1.5 and f(20)=56f(20)=56. Fill in the blanks (including units where needed) and select the appropriate terms to complete the following statement about the temperature of the coffee in this case. At minutes after the coffee was put on the counter, its temperature is and will ? by about in the next 45 seconds.
Answer:
A) f'(t) is negative
B) degc/min
c ) At 20 minutes after the coffee was put on the counter its temperature is 56degc and will decrease by about 1.125 in the next 45 seconds
Step-by-step explanation:
A ) f'(t) is Negative because as the cup of coffee is placed on the counter there is loss of heat from the cup of coffee to the surrounding as t increases hence f'(t) is negative
B ) The units of f'(20) = degc/min
C) At ║f'(20)║ = 1.5 and f'(20) = 56
║f'(20)║ = 1.5 represents the rate of change of temp every 20 minutes = 1.5
therefore after 45 seconds = 3/4 mins. change in temp = (3/4 * 1.5) = 1.125
At 20 minutes after the coffee was put on the counter its temperature is 56degc and will decrease by about 1.125 in the next 45 seconds
When Alvin woke up in the morning, it was
–
9°F. By the afternoon, the temperature had risen to
–
2°F.
What was the change in temperature from the morning to the afternoon?
Answer:
The answer to this question is: 7
The change in temperature from the morning to the afternoon is 7°F.
Given that, Alvin woke up in the morning, it was –9°F. By the afternoon, the temperature had risen to –2°F.
We need to find what was the change in temperature from the morning to the afternoon.
What is the change in temperature?Temperature change is a process whereby the degree of hotness of a body (or medium) changes.
You subtract the final temperature from the starting temperature to find the difference.
Now, change in teperature=-2-(-9)
=-2+9=7
Therefore, the change in temperature from the morning to the afternoon is 7°F.

Given:
x = 3
y = 1.5
We exchange these values into our equation (2x + 4y + 3x);
2x + 4y + 3x
Altered, would be:-
2(3) + 4(1.5) + 3(3)

15) First, we need to find the volume of the cube;
1/2(one side), but since all sides to a cube are equal we multiply that length by itself 3 times.
So;
1/2 x 1/2 x 1/2 = 1/8 is the volume of one cube.
Now we find the rectangular prism's volume, using the formula;
V(volume) = W x H x L
Where 'W' represents the width, 'H' represents the height, and 'L' represents the length.
Substitute these values in our formula:
V = W x H x L
V = 2 1/2 x 8 x 1/2
V = 5/2 x 8 x 1/2
V = 5/2 x 8/2
V = 5/2 x 4
V = 10
So now, we divide the total volume by the volume of one cube to get the total of how many cubes would be needed to fill this prism.
10 ÷ 1/8
10 x 8/1
10 x 8
= 80

The nth term of a sequence is 25 - 3n
Work out the first three terms of the sequence
Work out the first negative term of the sequence
Answer:
see explanation
Step-by-step explanation:
To find the first 3 terms substitute n = 1, 2, 3 into the formula
(a)= 25 - (3 × 1) = 25 - 3 = 22 = 25 - (3 × 2) = 25 - 6 = 19= 25 - (3 × 3) = 25 - 9 = 16
The first three terms are 22, 19, 16
Note the difference between consecutive terms is - 3
19 - 22 = 16 - 19 = - 3
Continuing this pattern
(b)16 - 3 = 13 13 - 3 = 10 10 - 3 = 7 7 - 3 = 4 4 - 3 = 1 1 - 3 = - 2
The first negative term is - 2

Purchases made at small "corner stores" were studied by the authors of a certain paper. Corner stores were defined as stores that are less than 200 square feet in size, have only one cash register, and primarily sell food. After observing a large number of corner store purchases in Philadelphia, the authors reported that the average number of grams of fat in a corner store purchase was 21.8. Suppose that the variable
x = number of grams of fat in a corner store purchase
has a distribution that is approximately normal with a mean of 21.8 grams and a standard deviation of 7 grams.
a) What is the probability that a randomly selected corner store purchase has more than 29 grams of fat?
b) What is the probability that a randomly selected corner store purchase has between 15 and 25 grams of fat?
c) If two corner store purchases are randomly selected, what it the probability that both of these purchases will have more than 25 grams of fat?
Answer: x = number of grams of fat in a corner store purchase
has a distribution that is approximately normal with a mean of 21.8 grams

If you have 250 toothpicks, and want to make them into a pyramid (shown in photo), how many levels will it make?
I know there are 12 rows shown in the photo, but I'm not sure of the equation you need in order to actually find that there are 12 levels. Could anyone tell me? Thanks! :)
Answer:
12 full levels
Step-by-step explanation:
There are multiple ways to do this, what I prefer is recursion
Let's define a equation which helps us determine the number of toothpicks of a pyramid with x levels f(x)
f(1)=3
f(2)=9
f(3)=18
f(4) =30
Etc Etc...
Eventually we can see that for every level x×3 toothpicks are added to f(x-1), so
f(x) = 3*x + f(x-1), so this becomes a geometric sequence 3*(1+2+3...+x)
Now we want to find out how many levels 250 toothpicks can make
250=3*(1+2+3+4..+x)
250/3 = 1+2+3...
I assume you want full levels so I will round down the answer, the closest you can get to 250/3 is (1+2+3...12)
So 12 full levels and a bit of extra toothpicks left
There are 12 full levels it will make.
What is a triangular pyramid?Take a traingle. This is a base. Now take 3 triangles such that each of them are connected to one-one side of the first traingle and when they're taken together, they form a closed object, called as a triangular pyramid.
here a equation which helps us determine the number of toothpicks of a pyramid with x levels f(x)
f(1)=3
f(2)=9
f(3)=18
f(4) =30
we can see that for every level x×3 toothpicks are added to f(x-1), so
f(x) = 3x + f(x-1), so geometric sequence 3*(1+2+3...+x)
Now we want to find out how many levels 250 toothpicks can make;
250=3*(1+2+3+4..+x)
250/3 = 1+2+3...
Thus, the closest we can get to 250/3 is (1+2+3...12)
Hence, 12 full levels and a bit of extra toothpicks left

An election poll of 1,000 people indicates that 48 percent of voters favor Candidate Smith and 50 percent of voters favor Candidate Jones, with a 3 percent margin of error. What can one conclude from this poll
The election poll indicates a close race between Candidate Smith and Candidate Jones, with a margin of error of 3 percent.
Given that,
Election poll of 1,000 people conducted
48 percent of voters favor Candidate Smith
50 percent of voters favor Candidate Jones
Margin of error is 3 percent
Based on the election poll,
We can conclude that there is a close race between Candidate Smith and Candidate Jones.
With Candidate Smith at 48 percent and Candidate Jones at 50 percent, it suggests a tight competition.
However, it's important to consider the margin of error of 3 percent.
This means that the actual support for each candidate could vary within this range.
Therefore, while this poll provides valuable insights, it is not definitive and other factors should also be considered.

"The product of a six and a number increased by four is equal to
the product of twelve and the same number decreased by twenty."
Answer:
[tex] 6x + 4 = 12x - 20 [/tex]
[tex] x = 4 [/tex]
Step-by-step explanation:
Let "x" be the number.
Product of 6 and x (6*x), increased by 4 = [tex] 6x + 4 [/tex]
Product of 12 and x, (12*x), decreased by 20 = [tex] 12x - 20 [/tex].
Set both expressions equal to each other and solve for x as shown below:
[tex] 6x + 4 = 12x - 20 [/tex] (equation)
Subtract 12 from both sides
[tex] 6x + 4 - 12x = 12x - 20 - 12x [/tex]
[tex] -6x + 4 = -20 [/tex]
Subtract 4 from both sides
[tex] -6x + 4 - 4 = -20 - 4 [/tex]
[tex] -6x = -24 [/tex]
Divide both sides by -6
[tex] \frac{-6x}{-6} = \frac{-24}{-6} [/tex]
