The graph of y = StartRoot x EndRoot is transformed as shown in the graph below. Which equation represents the transformed function?
On a coordinate plane, a curve opens up and to the right. It starts at (0, 2) and then decreases through (4, 0) into quadrant 4.
y = negative StartRoot x EndRoot
y = StartRoot (negative x) EndRoot + 2
y = StartRoot (negative x) EndRoot minus 2
y = negative StartRoot x EndRoot minus 2
Answer:
answer a did the test edg 2021
Step-by-step explanation:
Using translation concepts, it is found that the equation that represents the transformed function is:
[tex]y = -\sqrt{x-4} + 2[/tex]
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
In this problem, the original graph is:
[tex]y = \sqrt{x}[/tex]
It moves up, while the new graph moves down, hence:
[tex]y = -\sqrt{x}[/tex]
It starts at (0,0), while the new graph starts at (0,2), hence:
[tex]y = -\sqrt{x} + 2[/tex]
It also goes through (4,0), that is, it was shifted 4 units to the right, hence:
[tex]y = -\sqrt{x+4} + 2[/tex]

estimate: 4 1/2 - 3 5/6
Answer:
2/3
Step-by-step explanation:
[tex]4\frac{1}{2} -3 \frac{5}{6}[/tex]
1. Turn it into an improper fraction
[tex]4\frac{1}{2}[/tex] = [tex]\frac{9}{2}[/tex]
[tex]3\frac{5}{6}[/tex] = [tex]\frac{23}{6}[/tex]
[tex]\frac{9}{2} -\frac{23}{6}[/tex]
Now find a common denominator and in this case, it can be 6
[tex]\frac{9*3}{2*3} = \frac{27}{6}[/tex]
[tex]\frac{27}{6} - \frac{23}{6}[/tex] = ....
[tex]\frac{4}{6} =\frac{2}{3} (simplified)[/tex]
The solution is , 4 1/2 - 3 5/6 = 2/3.
What is Subtraction?Subtraction is the process of taking away a number from another. It is a primary arithmetic operation that is denoted by a subtraction symbol (-) and is the method of calculating the difference between two numbers.

What are the zeros of f(x) = x^2 + x - 20?
Answer:
{-5, 4}
Step-by-step explanation:
Start by factoring f(x) = x^2 + x - 20. Since 4*5 = 20, we suspect that the factors are (x + 5) and (x - 4).
Next, set these factors equal to zero separately and solve each resulting equation for x. We get:

The figure shows two semicircles. Find the area of the shaded part in terms of pi. Please explain in detail thank you!
Answer: 3pi/2
This is equivalent to 1.5pi
The units for the area are in square centimeters.
===============================================
Work Shown:
The larger semicircle has radius 2 cm.
So r = 2 is plugged into the area of a semicircle formula below
A = (pi*r^2)/2
A = (pi*2^2)/2
A = (4pi)/2
A = 2pi
The area of the larger semicircle is 2pi square cm.
Repeat those steps but now use r = 1. This will compute the area of the unshaded smaller semicircle
A = (pi*r^2)/2
A = (pi*1^2)/2
A = pi/2
The area of the smaller unshaded semicircle is pi/2 square cm.
------------------------
From here, we subtract the two results to get the shaded area:
(larger semicircle area) - (smaller semicircle area) = (2pi) - (pi/2) = 3pi/2
This is equivalent to 1.5pi since 3/2 = 1.5

What is the rate in miles per gallon: gallons used: miles; 28 628.4 39 947.7 42 1020.6
Answer:
Step-by-step explanation:
What is the rate in miles per gallon:
gallons used: 28 39 42
miles; 628.4 947.7 1020.6
The answer is below
Solution:
A linear function is a function in the form:
y = mx + b; where y is a dependent variable, x is an independent variable, m is the rate of change of y with respect to x, and b is the initial value of y when x is zero.
From the table, we are given the gallon used to cover a distance in miles. To calculate the rate, we can select two points from the table. Using the points in the form (miles, gallons used): (628.4, 28) and (1020.6, 42) we get:
[tex]m=\frac{1020.6-628.4}{42-28}\\\\m=28\ miles\ per\ gallon[/tex]

Problem: Find an evuivalent ratio in simplest terms
12:32
Answer:
simply divide the numerator and denominator by 4 (the GCF). So, 1232 = 12÷432÷4 = 38. Thus, 1232 is equivalent to 38 in the reduced form. (*) The factors are numbers that multiply each other to get another number.Step-by-step explanation:
Answer:
3:8
Step-by-step explanation:
We can simplify the ratio 12 : 32 by dividing both terms by the greatest common factor (GCF).
The GCF of 12 and 32 is 4.
Divide both terms by 4.
12 ÷ 4 = 3
32 ÷ 4 = 8
Therefore:
12 : 32 = 3 : 8

A regular polygon has 72 sides.
Find the size of each of its interior angles.
The formula for finding the measure of each interior angle is below.
180(n - 2) / n where n represents the number of sides.
Since the polygon has 72 sides, we plug a 72 in for n.
So we have 180(72 - 2)/72 or 180(70)/72 which is 12600/72 or 175.
So the measure of each interior angle is 175 degrees.

solve the system of equations:
-5x+2y=1
-8x+9y=19
X=?
Y=?
2y=1+5x (moving 5x to the other side) {equation 1}
Y= (1+5x)/2 (dividing both sides by 2)
Substitute {Y=(1+5x)/2} into equation: (-8x+9y=19)
Therefore giving you:
-8x+9(1+5x)/2=19
-8x+(9+45x)/2=19
(multiply through by 2 to remove the fraction)
-16x+9+45x=38
45x-16x=38-9(grouping like terms)
29x=29
Divide both sides by 29
X=1
Substitute X=1 into equation (-5x+2y=1)
-5(1)+2y=1
(-5)+2y=1
2y=1+5
2y=6
2y/2=6/2 (dividing both sides by 2)
Y=3.
:X=1 and Y=3
Answer:
X = 1
Y = 3
Step-by-step explanation:
Given equations are;
-5x+2y=1 Eqn 1
-8x+9y=19 Eqn 2
Multiplying Eqn 1 by -8
-8(-5x+2y=1)
40x - 16y = -8 Eqn 3
Multiplying Eqn 2 by 5
5(-8x+9y=19)
-40x+45y=95 Eqn 4
Adding Eqn 3 and 4
40x - 16y - 40x + 45y = 95 - 8
29y = 87
Dividing both sides by 29
[tex]\frac{29y}{29}=\frac{87}{29}\\y = 3[/tex]
Putting y = 3 in Eqn 1
-5x + 2(3) = 1
-5x + 6 = 1
-5x = 1 - 6
-5x = -5
x = 1
Hence,
X = 1
Y = 3
