Pauley graphs the change in temperature of a glass of hot tea over time. He sees that the function appears to decrease quickly at first, then decrease more slowly as time passes. Which best describes this function? It is linear because the graph decreases over time. It is linear because there is both an independent and a dependent variable. It is nonlinear because linear functions are increasing functions. It is nonlinear because linear functions increase or decrease at the same rate.

Answers

Answer:

It is nonlinear because linear functions increase or decrease at the same rate.

Step-by-step explanation:

A linear function is a function with a constant rate of change. This means it increases or decreases at the same rate.

Since this function decreases quickly and then more slowly, it does not have a constant rate of change; it is not linear.

Math quest after a winter storm, the depth of the snow on cherry street was 10 \text{ cm}10 cm10, space, c, m. but then, the snow started melting at a rate of \dfrac{1}{3} \text{ cm}31 cmstart fraction, 1, divided by, 3, end fraction, space, c, m per hour.what was the depth of the snow on cherry street after 333 hours?

Answers

We are given that the initial depth of snow is 10 cm while the rate of melting is 1/3 cm per hour. So the melted ice after 3 hours is:

melted = (1/3 cm/hr) * 3 hours = 1 cm

Hence the depth left is:

depth = 10 cm – 1 cm = 9 cm

Answer:

9 cm

Answer:

9 cm.

Step-by-step explanation:

Let x be the number of hours.

We have been given that after a winter storm, the depth of the snow on cherry street was 10 cm. Then, the snow started melting at a rate of [tex]\frac{1}{3}[/tex], so the snow melted in x hours will be [tex]\frac{1}{3}x[/tex].

Since initially there was 10 cm of snow, so the depth of snow after x hours will be:

[tex]10-\frac{1}{3}x[/tex]

To find the depth of snow after 3 hours we will substitute [tex]x=3[/tex] in our expression.

[tex]10-\frac{1}{3}\times 3[/tex]

[tex]10-1[/tex]

[tex]9[/tex]

Therefore, the depth of the snow on cherry street after 3 hours will be 9 cm.

Assume that the set s has 8 elements. how many subsets of s have at most 2 elements?

Answers

C(n,k) = n! / k! (n - k)! = number of k-combinations from a set of n elements.

The subsets of S that have 0, 1 or 2 elements include C(11,0) empty set, (C11,1) 1-element sets and (C11,2) 2-element sets.

C(11,0) = 11! / 0! 11! = 11! / 1×11! = 1
C(11,1) = 11! / 1! 10! = 10!×11 / 1×10! = 11
C(11,2) = 11! / 2! 9! = 9!×10×11 / 2×9! = 10×11/2 = 55

The total number of subsets of S that have at most 2 elements is
1 + 11 + 55 = 67

A cab charges 1.45 for the flat fee and 0.55 for each mile. Write and solve an inequality to determine how many miles Ariel can travel if she has 35 dollars to spend

Answers

m = mile

.55m + 1.45 [less than or equal to] 35

subtract 1.45

.55m = 33.55

divide by .55

m = 61 miles or less

y>ax+b

b: A cab charges 1.45 for the flat fee
a: and 0.55 for each mile
x: miles she can travel
y: total money she has (35$)

so: 35>0.55 x + 1.45

solve for x:

0.55 x < 35 - 1.45

x< 61

Given the system of equations, what is the solution?
x + 2y = 7
x - 2y = -1

(A.) {(-8, -12)}
(B.) {(3, 2)}
(C.) {(-4, 6)}

Answers

We can do the elimination method to find the solution for this problem. The elimination method involves adding the two equations together to get rid of a like term.

x + 2y = 7
+ x - 2y = -1
—————————
2x = 6

Now that we eliminated 2y because they cancel out, we are left with 2x = 6. Divide both sides by 2 in order to get x.

The answer is: x = 3.

Now that we know the numerical value of x, all we have to do is plug x into either system of equation in order to find the numerical value of y.

x + 2y = 7

3 + 2y = 7

2y = 4

y = 2

The solution to the problem is (3, 2).

Final answer:

The solution to the system of equations x + 2y = 7 and x - 2y = -1 is found by eliminating y, yielding x=3 and y=2, which is option B, (3, 2).

Explanation:

The solution to the system of equations x + 2y = 7 and x - 2y = -1 can be found by adding or subtracting the two equations to eliminate one of the variables. By adding the two equations, we eliminate y and get 2x = 6, which results in x = 3. Substituting x = 3 back into either of the original equations yields y = 2. Therefore, the solution to the system is (3, 2), which corresponds to option B.

If tap and bre are supplementary and bre is its own complement, find the measure of tap. explain how you arrived at your answer

Answers

Supplementary angles are those whose sum is equal to 180° while those that are complementary are those whose sum is equal to 90°. Since, we are given that bre is the complement of itself, its measure can be calculated through the equation,
m∠bre + m∠bre = 90°
m∠bre = 45°

Then, for the relationship of bre and tap, we have the equation,
m∠bre + m∠tap = 180°
45° + m∠tap = 180°
m∠tap = 135°

The measure of tap is equal to 135°.

Find the equation in standard form of the line with slope − 4 7 -47 that passes through the point ( 2 , 5 ) (2,5)

Answers

The standard form of the equation for a straight line is
y = mx + b
where m = the slope
b = y-intercept

The slope is -47, therefore
y = -47x + b

The line passes through (2,5), therefore
-47*2 + b = 5
-94 + b = 5
Add 94 to each side.
b = 5 + 94 = 99

The equation is y = -47x + 99

Answer: y = -47x + 99

Two angles are supplementary. one angle measures 12 degrees less than 5 times the other. find the measure of each angle

Answers

supplementary angles, when added, = 180 degrees

a + b = 180
a = 5b - 12

5b - 12 + b = 180
6b - 12 = 180
6b = 180 + 12
6b = 192
b = 192/6
b = 32 <=== one angle is 32 degrees

a = 5b - 12
a = 5(32) - 12
a = 160 - 12
a = 148 <=== the other angle is 148

Final answer:

The measures of the two supplementary angles are 32 degrees and 148 degrees, respectively.

Explanation:

The question is about finding the measures of two supplementary angles given the relationship between them. Supplementary angles are two angles whose measures add up to 180 degrees. If we let x be the measure of the first angle, then the measure of the second angle is 5x - 12 degrees, according to the problem statement.

Since the angles are supplementary, we can set up the following equation: x + (5x - 12) = 180. This simplifies to 6x - 12 = 180. Solving for x gives us x = 32, so the first angle measures 32 degrees.

Substitute x = 32 into the equation for the second angle gives us: 5x - 12 = 5(32) - 12 = 148 degrees. Therefore, the two angles measure 32 degrees and 148 degrees, respectively.
