Carlos drives 161 kilometers at a speed of 70 kilometers per hour. For how many hours does he drive?
Answer:
2.3 hours
Step-by-step explanation:
161 divided by 70 = 2.3
if Carlos drives 161 kilometers at a speed of 70 kilometers per hour then it takes 2.3 hours to drive.
What is Speed?Speed is the time rate at which an object is moving along a path,
Given,
Carlos drives 161 kilometers at a speed of 70 kilometers per hour
From the given data distance=161 kilometers
Distance is one hundred sixty one kilometers
Speed=70km/hr.
Speed is seventy kilometer per hour.
Speed=Distance/time
70=161/time
Now cross multiply
time=161/70
Time=2.3hrs
Hence, if Carlos drives 161 kilometers at a speed of 70 kilometers per hour then it takes 2.3 hours to drive.

The graph of the function y= x^2(x^2 - 6x + 9) has zeros of (0 and -3, -3 and 3, 0 and 3, -3 and 3)
complex zeros.
so the function has (no, two, three, four)
distinct real zeros and (no, two, three, four) complex zeros.
Answer: The answer is
1. 0 and 3
2. Two
3. No
Step-by-step explanation:
I took the test and it's right
The graph of the function has zeros of 0 and 3, two distinct real zeros, and no complex zeros.
What is a function?It is defined as a special type of relationship and they have a predefined domain and range according to the function.
We have a function:
[tex]\rm y= x^2(x^2 - 6x + 9)[/tex]
We can write it as a:
[tex]\rm y= x^2(x^2 - 2(3)(x)+ 3^2)[/tex]
[tex]\rm y = x^2(x-3)^2[/tex]
To find the zeros equate to the function with the zero.
y = 0
[tex]\rm x^2(x-3)^2=0[/tex]
First, take [tex]\rm x^2= 0[/tex] we get:
x = 0
Now
[tex]\rm (x-3)^2=0[/tex]
x - 3 = 0
x = 3
Thus, the graph of the function has zeros of 0 and 3, two distinct real zeros, and no complex zeros.

the complex solutions of which equation have a real component of 4.
(I'm not sure of what this is asking.)
Answer:
A.
Step-by-step explanation:
I just did this problem and guessed correctly.
The complex solutions of which equation have a real component of 4 is x² - 8x +16 +21 = 0.
What is Complex number?Complex numbers are numbers that consist of two parts — a real number and an imaginary number.
On solving all equation the correct one is x² - 8x +16 = -21.
Using discriminant method calculating the roots
x² - 8x +16 +21 = 0
x² - 8x + 37 = 0
x= -b ± √b² -4ac / 2a
x= 8 ± √ -8² - 4*1 * (37) /2a
x= 8 ± √- 84 / 2
x= 8 ± √2² *(- 21) /2
x=( 8 ± √2² *√21 i)/2
x= 8 / 2 ± 2i√21/2
x= 4 ± √21 i
So, x = 4+ √21 i and x= 4 - √21 i

Her friend Jane bought a 10.2 pound turkey and a 7.3 pound ham from the same store and paid
$24.84. Find the cost per pound of turkey and the cost per pound of ham.
Answer:
h = 1.74

Based on the graph below, which sequence of transformations is needed to carry ABCD onto its image A'B'CD?
Answer:
The third is correct.
Step-by-step explanation:
Preimage: A(2,3), B(5,6), C(8,6), D(8,3)
Image: A'(-2, 6); B'(-5,3); C'(-8,3); D'(-8,6)
Option 3.
Translation Rotation 180° Clockwise
(x, y-9) (-x,-y)
A(2,3) (2,-6) A' (-2,-6)
B(5,6) (5,-3) B' (-5,3)
C(8,6) (8,-3) C' (-8,3)
D(8,3) (8,-6) D' (-8,6)
Transformation involves changing the position of a shape.
The sequence of transformation is: (d) A translation rule by [tex]\mathbf{(x,y) \to (x, y - 9)}[/tex] and then a 180 degrees clockwise rotation about the origin
The coordinates of the pre-image is:
[tex]\mathbf{A = (2,3)}[/tex]
[tex]\mathbf{B = (5,6)}[/tex]
[tex]\mathbf{C = (8,6)}[/tex]
[tex]\mathbf{D = (8,3)}[/tex]
Of the given sequence of transformations, option (d) is correct.
The proof is as follows.
First, translate ABCD by (x, y - 9)
So, we have:
[tex]\mathbf{(x,y) \to (x, y - 9)}[/tex]
[tex]\mathbf{(2,3) \to (2, -6)}[/tex]
[tex]\mathbf{(5,6) \to (5, -3)}[/tex]
[tex]\mathbf{(8,6) \to (8, -3)}[/tex]
[tex]\mathbf{(8,3) \to (8, -6)}[/tex]
Next, rotate by 180 degrees.
The rule of this transformation is:
[tex]\mathbf{(x,y) \to (-x,-y)}[/tex]
So, we have:
[tex]\mathbf{(2,-6) \to (-2,6)}[/tex]
[tex]\mathbf{(5,-3) \to (-5,3)}[/tex]
[tex]\mathbf{(8,-3) \to (-8,3)}[/tex]
[tex]\mathbf{(8,-6) \to (-8,6)}[/tex]
From the graph, the coordinates of the image are:
[tex]\mathbf{A" = (-2, 6)}[/tex]
[tex]\mathbf{ B" = (-5,3)}[/tex]
[tex]\mathbf{C" = (-8,3)}[/tex]
[tex]\mathbf{D" = (-8,6)}[/tex]
Hence, the sequence of transformation is:
(d) A translation rule by [tex]\mathbf{(x,y) \to (x, y - 9)}[/tex] and then a 180 degrees clockwise rotation about the origin

Jerrod found the hypotenuse of a right triangle with legs 3 ft and 1 ft. Is his answer correct?
c2 = 32 + 12
c2 = 9 + 1
c2 = 8
c = 8
No, he setup the Pythagorean theorem incorrectly.
No, he made an error finding the square root.
No, he subtracted 1 and 9 instead of adding.
Yes, he correctly calculated the length of the hypotenuse
Answer:
The answer is no he is not correct, here's why.
C) No, he subtracted 1 and 9 instead of adding.
Step-by-step explanation:
Jerrod has found the hypotenuse, with the legs of 3 ft and 1 ft, his process is:
[tex]c^{2}[/tex] = 32 + 12
[tex]c^{2}[/tex] = 9 + 1
[tex]c^{2}[/tex] = 8
c = 8
The legs Jerrod said are 3 ft and 1 ft
so A and B of the formula of pythagorean theorem could be:
[tex]a^{2}[/tex] = (3)[tex].^{2}[/tex]
[tex]b^{2}[/tex] = (1)[tex].^{2}[/tex]
This leads us to:
[tex]3^{2} + 1^{2} = c^{2}[/tex]
which is:
9 + 1 = [tex]c^{2}[/tex]
10 = [tex]c^{2}[/tex]
In this case, Jerrod had calculated wrong by instead of adding he had subtracted.
(I don't know where he got 32 + 12, but other than that his process is correct other than calculation error)
The correct statement for given situation is,
⇒ No, Jerrod made an error to finding the square root.
What is mean by Triangle?Any triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
We have to given that;
Jerrod found the hypotenuse of a right triangle with legs 3 ft and 1 ft.
With steps are,
⇒ c² = 3² + 1²
⇒ c² = 9 + 1
⇒ c² = 8
⇒ c = 8
Now,
We have the steps are,
⇒ c² = 3² + 1²
⇒ c² = 9 + 1
⇒ c² = 8
⇒ c = 8
Clearly, In fourth step we get;
If c² = 8
Then, c = √ 8
But here we have;
⇒ c² = 8
⇒ c = 8
Hence, He made an error finding the square root.
Therefore, The correct statement for given situation is,
⇒ No, Jerrod made an error to finding the square root.

A bird goes from a higher location to a lower location at a
rate of 2 meters per second,
Which equation models the change in the bird's position at 30 seconds?
A. (-30)(-2) = -60
B. 30(-2) = -60
C. 30.2 = 60
D. 30(-2) = 60
Answer:
30(-2) = -60
Step-by-step explanation:
The change in speed from a higher location to a lower location is 2 m/s, v = -2 m/s (from higher to lower)
We need to find the equation that models the change in the bird's position at 30 seconds.
Distance = speed × time
change in position = (-2) × 30
= -60
Hence, the correct option is (B).

A sample of paint contains 3 ounces of blue paint and 8 ounces of yellow paint. If you have a 24 ounce can of the blue paint, how much yellow paint should you mix with it in order to make the same color as the sample? (Your answer should have numbers and units)
Answer:
64 ounces
Step-by-step explanation:
Given.
Represent blue with b and yellow with y
b = 3
y = 8
Required
What's the value of y when b = 24
Represent the given and required parameters as ratio
3 : 8 and 24 : y
Turn the ratio to an equation
3 : 8 = 24 : y
Represent as fraction
⅜ = 24/y
Multiply both sides by y
⅜y = 24
Make y the subject
y = 24 * 8/3
y = 64
Hence:
64 ounces of yellow paints is required for 24 ounces of blue paints

Which equation is the slope-intercept form of the equation of the line that passes through (1, 2) and is parallel to 4x - 2y = 6?
Answer:
The equation of the parallel line is y = 2x
Step-by-step explanation:
The slope-intercept form of the linear equation is:
y = m x + b, where
m is the slope of the line b is the y-intercept (value y at x = 0)Parallel lines have the same slopes and different y-intercepts
∵ The equation of the given line is 4x - 2y = 6
→ To find the slope of this line re-arrange it to be in the
slope-intercept form Subtract 4x from both sides to move x to
the right side
∵ 4x - 4x - 2y = 6 - 4x
∴ -2y = 6 - 4x
→ Divide both sides by -2 to make the coefficient of y = 1
∵ [tex]\frac{-2y}{-2}=\frac{6}{-2}-\frac{4x}{-2}[/tex]
∴ y = -3 - (-2x)
∴ y = -3 + 2x
→ Swithch -3 and 2x
∴ y = 2x - 3
→ Compare it by the form of the equation above to find m
∴ m = 2
∴ The slope of the given line is 2
∵ The two lines are parallel
∴ The slope of the parallel line is 2
→ Substitute it in the form of the equation above
∴ y = 2x + b
→ To find b substitute x and y in the equation by the coordinates
of any point on the line
∵ The line passes through the point (1, 2)
∴ x = 1 and y = 2
∵ 2 = 2(1) + b
∴ 2 = 2 + b
→ Subtract 2 from both sides to find b
∴ 2 - 2 = 2 - 2 + b
∴ 0 = b
∴ y = 2x
The equation of the parallel line is y = 2x
