Given f(x)= square root x and g(x) = lxl, which is the graph of (fog)(x)
Answer:
drawing the graph of [tex]f(g(x))=\sqrt{|x|}[/tex]
The graph is attached in the images below.
Option A is correct option.
Step-by-step explanation:
We are given:
[tex]f(x)=\sqrt{x}[/tex] and [tex]g(x)=|x|[/tex]
We need to find graph of (fog)(x)
We know that (fog)(x)= f(g(x))
Placing x=g(x) i,e x=|x|
[tex](fog)(x)= f(g(x))\\f(g(x))=\sqrt{|x|}[/tex]
Now, drawing the graph of [tex]f(g(x))=\sqrt{|x|}[/tex]
The graph is attached in the images below.
Option A is correct option.

Class comments
55° 60°
Answer:
Let's create this right triangle. We will call it triangle ABC with angle B as the right angle, angle A being the larger of the angles A and C. If the ratio is 5:4, then it is A:C. 5+4 = 9. The measure of the right angle, angle ABC = 90, and 90 divided by 9 is 10. So angle A is 5 * 10 which is 50 degrees, and angle C is 4 * 10 which is 40 degrees. The smallest angle, angle C, is 40 degrees.

1. The numerator of a certain fraction is 3 more than the denominator. If 3/2 is added to the fraction, the result is 4. Find the fraction.
2. If 3/8 is added to five times the reciprocal of a number, the result is 1. Find the number.
3. One car travels 390 miles in the same amount of time it takes a second car traveling 3 miles per hour slower than the first to go 372 miles. What are the speeds of the cars?
9514 1404 393
Answer:
5/2 8 65 mph, 62 mphStep-by-step explanation:
The first two problems can be solved in your head by working backward from the end result.
__
1. After 3/2 is added, the result is 4. Then we must be adding 3/2 to 4 -3/2 = 5/2. We notice that 5/2 already has the numerator 3 more than the denominator, so the fraction of interest is 5/2.
__
2. If 3/8 is added to a number giving a result of 1, the number must be 1 -3/8 = 5/8. That is 5 times 1/8. The number of interest is the reciprocal of 1/8, so is 8.
__
3. Let x represent the speed of the faster car. Then x-3 is the speed of the slower car, and the two times are ...
time = distance/speed
390/x = 372/(x-3)
390(x -3) = 372x . . . cross multiply
18x = 1170 . . . . . . . add 1170-372x
x = 65 . . . . . . . . . . divide by 18
The speeds of the cars are 65 mph and 62 mph.
Write the slope of a line perpendicular to y=-6x+4. Explain why it is perpendicular
Answer:
1/6 is the slope since you have to flip it
Step-by-step explanation:
Answer:
The slope of a line perpendicular to the equation is 1/6 or x/6.This is perpendicular because it is the reciprical of the other equation
Step-by-step explanation:
y=-6x+4.
the slope intercept form is y=mx+b
m is the slope
m=-6
for the equation to be perpendicular then the slope is the reciprical
Knowing this lets find a line perpendicular to this equation
Equation:
y=1/6x+2/3
or
y=x/6+2/3

Can Someone Help with This Distributive Property Math Question :
1. - ( 8x - 12 )
Answer:
-8x+12
Step-by-step explanation:
1. You need to distribute the (-1) from outside the bracket onto all the terms in the bracket, which includes (8x) and (-12). If there is a minus outside the bracket and one minus in the bracket, the operation would be a plus and vice versa. If there is a minus outside the bracket and one plus in the bracket, the operation would be a minus and vice versa.
- (8x - 12) = (-1) × (8x) + (-1) × (-12)
= -8x + (+12)
= -8x + 12

17. Your class wants to raise at least $100 for a charity by collecting bottles. Each glass bottle earns $0.05. Each plastic
bottle earns $0.10.
a. Describe the numbers of glass bottles your class needs to collect if no plastic bottles are collected.
b. Describe the numbers of plastic bottles your class needs to collect if no glass bottles are collected.
c. Write an inequality that represents how many of each type of bottle your class can collect to reach the goal.
Considering the definition of an inequality, you get:
a. the numbers of glass bottles your class needs to collect if no plastic bottles are collected is 2000.
b. the numbers of plastic bottles your class needs to collect if no glass bottles are collected is 1000.
c. the inequality that represents how many of each type of bottle your class can collect to reach the goal is 0.05×g + 0.10s≥100.
Definition of inequalityAn inequality is the existing inequality between two algebraic expressions, connected through the signs:
greater than >.less than <.less than or equal to ≤.greater than or equal to ≥.An inequality contains one or more unknown values called unknowns, in addition to certain known data.
Solving an inequality consists of finding all the values of the unknown for which the inequality relation holds.
Inequality in this caseIn this case, you know that:
Your class wants to raise at least $100 for a charity by collecting bottles.Each glass bottle earns $0.05. Each plastic bottle earns $0.10.Being:
"g" the numbers of glass bottles your class needs to collect."p" the numbers of plastic bottles your class needs to collect.a. the numbers of glass bottles your class needs to collect if no plastic bottles are collected is calculated as:
0.05×g≥100
Solving:
g≥100÷ 0.05
g≥2000
b. the numbers of plastic bottles your class needs to collect if no glass bottles are collected is calculated as:
0.10×s≥100
Solving:
s≥100÷ 0.10
s≥1000
c. the inequality that represents how many of each type of bottle your class can collect to reach the goal is:
0.05×g + 0.10s≥100
In summary, you get:
a. the numbers of glass bottles your class needs to collect if no plastic bottles are collected is 2000.
b. the numbers of plastic bottles your class needs to collect if no glass bottles are collected is 1000.
c. the inequality that represents how many of each type of bottle your class can collect to reach the goal is 0.05×g + 0.10s≥100.

Farell has a gift card with a 45 balance he bought some bags of chips that cost 2.50 each after his perchase his gift card balance was 32.50 write and solve the equation to find how how many bags of chips x he bought
Answer:
He bought 5 bags of chips
Step-by-step explanation:
Here, we want to calculate the number of bags of chips bought
The amount used on the balance is;
45-32.5 = 12.5
Let the number of chips bought be n
Since each chip cost 2.5 each;
The amount of chips bought will be 2.5 * n = 2.5n
This is same as 12.5
Thus;
2.5n = 12.5
n = 12.5/2.5
n = 5

Answer:
I think it may be y=2X+1 hope it's right
Answer:
D
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 1, 1) and (x₂, y₂ ) = (0, - 1) ← 2 points on the line
m = [tex]\frac{-1-1}{0+1}[/tex] = - 2
The line crosses the y- axis at (0, - 1) ⇒ c = - 1
y = - 2x - 1 ← equation of line
Find the 9th term of the geometric sequence 9,27,81...
Answer:
59049
Step-by-step explanation:
The pattern is that it multiplies by 3 every time.
9*3=27, and 27*3=81.
81*3 = 243
243*3 = 729
729*3=2187
2187*3=6561
6561*3=19683
19683*3 = 59049

When a coin is tossed 20 times, it lands on heads 5 times. How does the experimental probability differ from the theoretical probability?
Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Number of tosses / trials = 20
Number of heads = 5
The experimental probability = the actual output of am event when an experiment or test is carried out :
Experimental probability = number of occuences / number of trials
That is :
P(head) = 5 / 20 = 1/4
Theoretical probability could be regarded as the expected output of an event based on the mathematical calculation :
Required outcome / Total possible outcomes
Theoretical probability P(head) in a toss = 1/2

5. Factorise: p2 - 11p +30
Answer:
(p - 5)(p - 6)
Step-by-step explanation:
p^2 - 11p + 30
find what two numbers added together is -11 but multiplies together is 30, its' -5 and -6 so:
(p - 5)(p - 6)
Answer:
(p - 5)(p - 6)
Step-by-step explanation:
Given
p² - 11p + 30
Consider the factors of the constant term (+ 30) which sum to give the coefficient of the x- term (- 11)
The factors are - 5 and - 6, since
- 5 × - 6 = + 30 and - 5 - 6 = - 11 , thus
p² - 11p + 30 = (p - 5)(p - 6) ← in factored form
how many integers satisfy -5≥-7x and -15≥5x
The number of integers that satisfies the inequalities, -5 ≥ -7•x and -15 ≥ 5•x is zero or non
How can the inequalities be simplified?The given inequalities are;
-5 ≥ -7•x and -15 ≥ 5•x
Simplifying the inequalities gives;
-5 ≥ -7•x
Dividing both sides by -7 gives;
-5/-7 ≤ -7•x/-7 = x
Therefore;
5/7 ≤ x
Which gives;
x ≥ 5/7The second inequality is simplified as follows;
-15 ≥ 5•x
-15/5 ≥ 5•x/5
-3 ≥ x
Which gives;
x ≤ -3
Therefore;
-3 ≥ x and x ≥ 5/7
5/7 ≤ x ≤ -3
However, 5/7 > -3
The number of integers that satisfies the inequality, 5/7 ≤ x ≤ -3, is zero (no integer satisfies the inequality).
Therefore;
Non of the integers satisfies both -5 ≥ -7•x and -15 ≥ 5•x
