Option B is correct, f(x) = 2ˣ is an exponential parent function.
What is a function?A relation is a function if it has only One y-value for each x-value.
The exponential parent function is of the form:
f(x) = aˣ
where a is a positive constant (the base of the exponential function).
Among the given options, the exponential parent function is,
⇒ f(x) = 2ˣ,
Because it has the form of an exponential function, where the base is 2.
f(x) = x is a linear function, not an exponential function.
f(x) = |x| is an absolute value function, not an exponential function.
f(x) = x² is a quadratic function, not an exponential function.
Hence, f(x) = 2ˣ is an exponential parent function, Option B is correct.

Which is the product of 5/18 and 6?
the ratio of boys to girls is 15:11 .if boys are 435 find the number of girls
Answer:
[tex]Girls = 319[/tex]
Step-by-step explanation:
Given
[tex]Boys: Girls = 15:11[/tex]
Required
Find Girls, when Boys = 435
Substitute 435 for Boys
[tex]435: Girls = 15:11[/tex]
Express as fraction
[tex]\frac{Girls}{435} = \frac{11}{15}[/tex]
Multiply through by 435
[tex]435 * \frac{Girls}{435} = \frac{11}{15}* 435[/tex]
[tex]Girls = \frac{11}{15}* 435[/tex]
[tex]Girls = \frac{11* 435}{15}[/tex]
[tex]Girls = \frac{4785}{15}[/tex]
[tex]Girls = 319[/tex]
How do I solve this question
Answer:
6) x = 6.75
7) x = 27.29
Step-by-step explanation:
cross multiply
6)_______________________
9/16 = x/12
16x = 108
divide by 16
x = 6.75
7)_______________________
7/11 = 18/x + 1
7x + 7 = 198
-7 -7
7x = 191
divide by 7
x = 27.29

Answer:
x=4 z=117
Step-by-step explanation:
Answer:
x = 4, z = 117
Step-by-step explanation:
14x + 7 and 63 are vertically opposite angles and are congruent, then
14x + 7 = 63 ( subtract 7 from both sides )
14x = 56 ( divide both sides by 14 )
x = 4
z and 63 are adjacent angles and are supplementary, then
z + 63 =180 ( subtract 63 from both sides )
z = 117
Please help is for now
Answer:
[tex]\Huge\boxed{-8}[/tex]
Step-by-step explanation:
Hello there!
When given two ordered pairs we can use the slope formula to solve for the slope
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
where m = slope
All we have to do is plug in the y and x values into the formula and calculate the slope
[tex]m=\frac{1-9}{7-6} \\1-9=-8\\7-6=1\\\frac{-8}{1} =-8\\m=-8[/tex]
So we can conclude that the slope of the line that passes through the points (6,9) and (7,1) is -8

It takes Tony 15 hours to rake the front lawn while his brother, Jose, can rake the lawn in 12 hours. How long will it take them to take the lawn working together?
Answer:
they can finish
[tex] \frac{1}{15} + \frac{1}{12} \\ [/tex]
in one hour
[tex] \frac{4 + 5}{60} \\ \frac{9}{60} [/tex]
in 6 hours they can finish
[tex] \frac{9}{60} \times 6 \\ \frac{54}{60} [/tex]
so the left work
[tex] \frac{60 - 54}{60} [/tex]
[tex] \frac{6}{60} [/tex]
they can perform
[tex] \frac{3}{60} work in60 \: minutes \div 3[/tex]
so the can perform
[tex] \frac{6}{60} work \: in \: 20minutes \times 2[/tex]
the take 6 hours and 40 minutes

Plz help ASAP 20 Points Determine the equation of circle A.
(x - 1)2 + (y + 2)2 = 9
(x + 1)2 + (y-2)2 = 9
(x-1)2 + (y + 2)2 = 3
(x + 1)2 + (y-2) = 3
Answer:
the answer is c
Step-by-step explanation:
your equation is to solve the circle so A could not be the answer B/c it can't be 9.the answer is c or d. But d can't give you 3 if you solve it. so the answer is C

Step-by-step explanation:
Because the volume is either 0.15 more or 0.15 less than 21 ounces. [tex]| v - 21 |[/tex] indicate the difference between the volume and 21 and it has to be less than 0.15. Therefore answer C.

Can someone help me with this plz??
Answer:
f(x) = -4x-1
f(7) = -(4)(7)-1
f(7) = -29
g(x) = 4x^2 - x
g(-4) = 4(-4)^2 - (-4)
g(-4) = 4(16) + 4
g(-4) = 64 + 4
g(-4) = 68

In an agricultural experiment, the effects of two fertilizers on the production of oranges were measured. Thirteen randomly selected plots of land were treated with fertilizer A, and 8 randomly selected plots were treated with fertilizer B. The number of pounds of harvested fruit was measured from each plot. Following are the results.
Fertilizer A
445 510 464 472 441 480 403 460 448
457 437 505 417
Fertilizer B
398 380 368 393 424 387 378 415
Required:
Construct a 95% confidence interval for the difference between the mean yields for the two types of fertilizer.
Answer:
The 95% confidence interval for the difference between the mean yields for the two types of fertilizer is approximately 92.5536 pounds < [tex]\bar{x}_{1}- \bar{x}_{2}[/tex] < 35.39 pounds
Step-by-step explanation:
The harvest from each plot treated with fertilizer A and fertilizer B are presented as follows;
Fertilizer A
445, 510, 464, 472, 441, 480, 403, 460, 448, 457, 437, 505, 417
Fertilizer B
398, 380, 368 393, 424, 387, 378, 415
The number of trials of fertilizer A, n₁ = 13
The number of trials of fertilizer B, n₂ = 8
The confidence level = 95%
α = 1 - 0.95 = 0.05
∴ α/2 = 0.025
The degrees of freedom, df = 8 - 1 = 7
[tex]t_{\alpha /2}[/tex] = 2.365
From Microsoft Excel, we get;
The standard deviation of the pounds of harvested fruits for the plots treated with fertilizer A s₁ = 30.71603
The mean of the pounds of harvested fruits for the plots treated with fertilizer A, [tex]\overline x_1[/tex] = 456.8462
The standard deviation of the pounds of harvested fruits for the plots treated with fertilizer B s = 18.99201
The mean of the pounds of harvested fruits for the plots treated with fertilizer B, [tex]\overline x_2[/tex] = 392.875
The 95% confidence interval, C.I. for the difference between the mean yields for the two types of fertilizer can be constructed with the following formula
[tex]C.I. = \left (\bar{x}_{1}- \bar{x}_{2} \right )\pm t_{\alpha /2} \cdot \sqrt{\dfrac{s_{1}^{2}}{n_{1}}+\dfrac{s_{2}^{2}}{n_{2}}}[/tex]
By variable substitution, we get;
[tex]C.I. = \left (456.8462- 392.875 \right )\pm 2.635 \times \sqrt{\dfrac{30.71603^{2}}{13}+\dfrac{18.99201^{2}}{8}}[/tex]
The 95% confidence interval for the difference between the mean yields for the two types of fertilizer [tex]C.I. \approx 63.9712 \pm28.5824[/tex], which can be expressed as 92.5536 lbs. < [tex]\bar{x}_{1}- \bar{x}_{2}[/tex] < 35.39 lbs.
