Help please Ive been struggling on this question
Explanation:
Locate the point that has x = -3 as its x coordinate. The y coordinate is the output of the function when we use this x value. So the point (-3,-7) means that f(-3) = -7. As another example, f(2) = 3.
is this table proportional or non-proportional?
Answer:
Proportional
Step-by-step explanation:
Proportional functions can be written as [tex]y=kx[/tex], where [tex]k[/tex] is some constant of proportionality. Plugging in (x,y) pair into this function will yield a constant of proportionally of [tex]k=\frac{3}{2}[/tex] and since this constant is maintained through all the coordinate pairs in the table, the table is proportional.

So for this answer I got 5 hrs. > 38.13 - 12 = 26.13/4.75 = 5 (rounded). However, my answer is wrong. Not sure how else I can solve this. Please help.
9514 1404 393
Answer:
38.13 = 12 +4.75h
5.5 hours
Step-by-step explanation:
(a) The charge (c) for renting a bike for h hours is ...
c = helmet charge + hourly charge × hours
c = 12.00 +4.75h
To find the number of hours when the charge is 38.13, we would use the equation ...
38.13 = 12.00 +4.75h
__
(b) To solve this 2-step linear equation, we first subtract the constant
26.13 = 4.75h
then we divide by the coefficient of the variable.
26.13/4.75 = h ≈ 5.5
Amanda rented the bike for 5.5 hours.

Step-by-step explanation:
-9-(-4)
solve the one in the bracket first because there is a minus sign between 9 and the bracket so we cannot use the 9 to multiple the number four in the bracket.
-9+4
the sign has changed to positive because when negative numbers are multiplying each other to will turn in to become positive.
so -9+4= -5

-9-(-4)
-9+4
-9+4= -5

A gene for sweat gland production is found on the X chromosome. If a man who lacks sweat glands marries a woman who has normal sweat glands, what will be the phenotype of their children?A. All of the boys will lack sweat glands.B. All of the girls will lack sweat glands.C. The girls will have sweat glands in some areas, but lack sweat glands in others.D. All of the boys will have sweat glands.E. All the boys will have sweat glands, and the girls will have sweat glands in some areas but not others.
Answer:
Option D, All of the boys will have sweat glands
Step-by-step explanation:
Given -
Gene for sweat gland production is found on the X chromosome
Genotype of man - lacks sweat glands (XY)
Genotype of women - has normal sweat glands (X'X')
X' - sweat glands
X - no sweat glands
This is an X linked recessive trait
If these two mates, then the all males will have sweat glands
X'X' * XY ---> X'X, X'X, X'Y, X'Y
Option D, All of the boys will have sweat glands

Answer:
140°
Step-by-step explanation:
Angles 1 and 3 are "corresponding" angles, so are congruent.
∠1 = ∠3
20x +60 = 30x +20
40 = 10x . . . . . . . . . . . . subtract 20x+20
4 = x . . . . . . . . . . . . . . divide by 10
∠1 = 20x +60 = 20(4) +60 = 80 +60
∠1 = 140°
Answer:
140°
Step-by-step explanation:
Angle 1 and angle 3 are corresponding angles ;
Corresponding angles are equal ;
Hence,
Angle 1 = Angle 3
20x + 60 = 30x + 20
Collect like terms
20x - 30x = 20 - 60
-10x = - 40
x = 4
Angle 1 is thus :
20x + 60 ; x = 4
20(4) + 60
80 + 60
= 140°

Explanation:
f(x) is the outer function, so the final output -8 corresponds to f(x)
We see that f(-4) = -8 in the first column of the table. I'm starting with the output and working my way backward to get the input. So we started with -8 and worked back to -4.
Then we move to the g(x) function to follow the same pattern: start with the output and move to the input. We start at -4 in the g(x) bubble and move to 3 in the x bubble.
In short, g(3) = -4
So,
f(g(x)) = f(g(3)) = f(-4) = -8
We see that x = 3 leads to f(g(x)) = -8

This question did provide some clues to answer this question. Every week, the area covered by the algae is multiplied by 2^1.
To find the area cover increase by the algae per day, the exponent should be divided by 7 since there are 7 days in a week. Hence, every day, the area covered by the algae multiplies by 2^(1/7). In other words, 1 day after the algae was spotted, the area is 12.5 * 2^(1/7), which answers part B.
10 days after the algae was spotted, the area covered by the algae is 12.5 * 2^[(1/7)*10] = 33.6475... , which rounds up to 34 and answers part A.
