Select the correct answer. Exponential function f is represented by the table. x -2 -1 0 1 2 f(x) -46 -22 -10 -4 -1 Function g is represented by the equation. g ( x ) = − 18 ( 1 3 ) x + 2 Which statement correctly compares the two functions on the interval [-1, 2]? A. Only function f is increasing, but both functions are negative. B. Both functions are increasing, but function g increases at a faster average rate. C. Both functions are increasing, but function f increases at a faster average rate. D. Only function f is increasing, and only function f is negative.
The correct comparison between two function is
Both functions are increasing, but function g increases at a faster average rate.
The Correct option is (B).
What is an increasing function?If the slope of a function is continuously increasing or constant in an interval, the function is known as an increasing function.
Let us assume
f(x) = [tex]ab^x[/tex]+ c
so, at x=0, f(0)=-10
a +c = -10
Similarly, by satisfying the above table in the f(x)
f(x) = -33/5 [tex](1/11)^x[/tex] - 17/5
and, f'(x) > 0
Thus, f(x) is an increasing function.
Now, g(x) = -18 [tex](1/3)^x[/tex] +2
g'(x) = -18 [tex](1/3)^x[/tex] log(1/3)
as log 1/3 <0
So, g'(x) > 0
Thus, g(x) is an increasing function.
For any x ∈ f(x) and x ∈ g(x), g'(x) > f'(x).
Hence, Both functions are increasing, but function g increases at a faster average rate.

To calculate the surface area you have to count all of the squares. You can do this with these equations.
8 × 4 × 2 = 64
8 × 2 × 2 = 32
4 × 2 × 2 = 16
Next, add them up!
64 + 32 + 16 = 112
In a bag of candy, Marsha found that there were 7 red, 8 blue, 5 yellow, and 9 greens pieces of candy. Marsha put all of the pieces of candy back in the bag, and drew one piece of candy out.
Part A:
Complete the following chart to determine the probability that Marsha drew each of the following pieces of candy.
Part B:
Marsha now wishes to determine compound probability. Complete the following chart to determine the probability that Marsha drew each of the following pieces of candy.
If you cannot see, zoom in. Don’t answer if you don’t know the answer. Whoever answers correctly will get Brainliest!
Answer:
Step-by-step explanation:
1) find the total candies
7 + 8 + 5 + 9 = 29
2) a probability can be expressed with a fraction whose denominator is the total candies, while the numerator represents the candies that we want to find
- red = 7/29
- blue = 8/29
- yellow = 5/29
- green = 9/29
3) compound probability
(red + blue)/29 = 15/29
(yellow + green)/29 = 14/29
(blue + yellow + green)/29 = 22/29
What is the value of the expression below when x=2?
8x^2 +6x-8
8x

+6x−8
When we evaluate the expression 8x² + 6x - 8 in x = 2, we will get the value 36.
What is the value of the expression when x = 2?Here we need to evaluate the following expression:
8x² + 6x - 8
in x = 2.
Evaluating means that we need to replace the variable by the given number. Replacing the "x" by 2, we will get:
8*2² + 6*2 - 8
8*4 + 12 - 8
8*3 + 12
24 + 12 = 36
When x = 2, the expression is equal to 36.

From a sample of 40 students, it is found that 29 are taking algebra, 14 are taking physics, and 5 are enrolled in both. How many students are enrolled in either algebra or physics?
Algebra Not in Algebra Total

Total 29 11 40
it is found that 29 are taking algebra, 14 are taking physics, and 5 are enrolled in both using principle of inclusion-exclusion we can say 38 students are enrolled in either algebra or physics.
How to find the number of students enrolled in either algebra or physics?To find how many students are enrolled in either algebra or physics, you can use the principle of inclusion-exclusion, which states that the total number of elements in two sets can be found by adding the number of elements in each set and then subtracting the number of elements that are in both sets.
So, the number of students enrolled in either algebra or physics is:
29 (students enrolled in algebra) + 14 (students enrolled in physics) - 5 (students enrolled in both) = 38
So, 38 students are enrolled in either algebra or physics.
It is important to notice that in the table you provided is a two-way frequency table also known as a contingency table, it shows the relationship between two variables, in this case, Algebra and Physics and the frequencies of each combination.

function decreases as x increases
9514 1404 393
Answer:
function decreases(0, 2)y = 2(0, 4)Step-by-step explanation:
-f(x) reflects the graph over the x-axis. Instead of increasing everywhere, it decreases everywhere.
__
2f(x) stretches the graph vertically by a factor of 2. The y-intercept of (0, 1) gets moved to (0, 2)
__
f(x) +2 shifts the graph up 2 units. The horizontal asymptote moves from y=0 to y=2.
__
f(x+2) shifts the graph left 2 units. The point (2, 4) on the original graph gets translated to the y-axis to become the new y-intercept (0, 4).
lex has $1,780.80 in his savings in his saving account that he opened 6 years ago his account has an annual interest rate of 6.8% compounded annually how much money did lex use to open his savings
Answer:
To find the principal, P we can use the same formula, A=P(1+rn)nt. We have the balance of the account, A, after 6 years, $1,780.80. The interest rate, r, is 6.8% (or 0.68 as a decimal) and is compounded annually, so n=1. The time, t, is 6, since we know he opened his account 6 years ago. Plug in the known values into the formula and solve for the missing variable, P.
Step-by-step explanation:
1,780.80 = P (1+0.0681 divided 1^(6)
1,780.80= 1.484P
1,200=P the principal amount Lex used to open his account 6 years ago
In a chess club the probability that Shaun will beat Mike is 3/8 .
The probability that Shaun will beat Tim is 5/7 .
(Assume all the games are independent of one another)
If Shaun plays 1 game with Mike and then 1 game with Tim, what is the probability that Shaun loses both games?
Answer:
[tex]\frac{10}{56} = 0.1786[/tex] probability that Shaun loses both games
Step-by-step explanation:
Games are independent, so we find each separate probability, and multiply them.
In a chess club the probability that Shaun will beat Mike is 3/8.
So [tex]1 - \frac{3}{8} = \frac{8}{8} - \frac{3}{8} = \frac{5}{8}[/tex] probability that Shaun loses.
The probability that Shaun will beat Tim is 5/7 .
So [tex]1 - \frac{5}{7} = \frac{2}{7}[/tex] probability that Shaun loses.
What is the probability that Shaun loses both games?
This is:
[tex]p = \frac{5}{8} \times \frac{2}{7} = \frac{5*2}{8*7} = \frac{10}{56} = 0.1786[/tex]
[tex]\frac{10}{56} = 0.1786[/tex] probability that Shaun loses both games

Answer:
girls are 15 and boys are 30
Answer:
15 girls and 30 boysStep-by-step explanation:
Given,
No. of students in the class = 45
Fraction of girls = 1/3
Therefore,
No. of girls = 45 × 1/3
= 15
No. of boys = 45 - 15 = 30

What are the features of the quadratic function ƒ(x) = (x – 3)(x + 7)?
Answer:
See below
Step-by-step explanation:
I guess if you look at the zeroes/x-intercepts, we got (3,0) and (-7,0) as zeroes.
Additionally, we can calculate the minimum by expanding the function:
[tex](x-3)(x+7)=x^2+4x-21[/tex]
[tex]\displaystyle x=-\frac{b}{2a}=-\frac{4}{2(1)}=-2\\\\f(-2)=(-2)^2+4(2)-21=4+8-21=12-21=-9[/tex]
So the minimum of the function is (-2,-9)
Also, our y-intercept is (0,-21)
One integer is 5 less than another. The sum of their squares is 277
The equation is x² + y² = 277 and the value of x and y is 9 and 14 respectively
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the two number be x and y
One integer is 5 less than another
So , x = y - 5
x - y = -5 be equation (1)
And , sum of their squares is 277
So , x² + y² = 277 be equation (2)
On simplifying the equation , we get
( x - y )² = x² + y² - 2xy
Substituting the values in the equation , we get
( -5 )² = 277 - 2xy
2xy = 277 - 25
2xy = 252
And , ( x + y )² = x² + y² + 2xy
Substituting the values in the equation , we get
( x + y )² = 277 + 252
( x + y )² = 529
( x + y ) = 23 be equation (3)
Adding equation (1) and equation (3) , we get
2x = 18
x = 9
So , y = 14
Therefore , the value of x and y is 9 and 14 respectively

Is it ok to not put the p in this equation as the 3p is minus
Answer:

that's right. You do not put the p since 3p and -3p cancel out to give zero. I'll solve the question for you:-
⇒3p-3p+2s-6s+2q-3q+8r-7r
add or subtract the like terms(terms having same variables), then out of the two like terms, put the sign of the greater number, for e.g. 2q-3q = -1q
