Which is the graph of f(x) = (x + 3)(x – 2)? Image for option 1 Image for option 2 Image for option 3 Image for option 4
Answers
Answer:
image 1
Step-by-step explanation:
Given data:
f(x) = (x+3)(x-2)
= x^2 + x-6
As the given expression is a quadratic expression so the graph will be parabola.
Also coefficient of x^2 is 1, 1>0 hence we'll the parabola opens upwards
that reduces our options to image 1 and 2 only
now to find the x-axis points of parabola
let (x+3)(x-2)=0
(x+3)=0 and (x-2)=0
x= -3 and x= 2
when at y=0, x= -3 and x=2
hence the image 1 !

calculate the angle between the longest side and the diagonal of a 577mm by 1000mm rectangle
Answers
Final answer:
The angle between the longest side and the diagonal of a 577mm by 1000mm rectangle can be found by first calculating the diagonal using the Pythagorean theorem and then using the arccosine function to find the angle with the longest side.
Explanation:
To calculate the angle between the longest side of a 577mm by 1000mm rectangle and the diagonal, we first need to determine the length of the diagonal using the Pythagorean theorem. The diagonal (d) can be found using the formula d = [tex]\sqrt{(width^2 + height^2)}[/tex]. After calculating the diagonal, we can find the angle using trigonometric ratios, specifically the arccosine function or cos-1.
Step 1: Calculate the diagonal
d = [tex]\sqrt{(577mm^2 + 1000mm^2) }[/tex]= [tex]\sqrt{(333929 + 1000000) }[/tex] = [tex]\sqrt{1333929}[/tex] ≈ 1155mm
Step 2: Calculate the angle
The angle (θ) between the longest side (adjacent side) and the diagonal (hypotenuse) is given by:
θ = cos-1(adjacent side / hypotenuse) = cos-1(1000mm / 1155mm)
To find the angle, use a calculator to compute the arccosine of 1000/1155.

If k>1, then the graph of g(x) stretches vertically, and if k<1 then the graph of g(x) is compressed vertically.
Since k is, therefore the shoes the vertical compression.
What is vertical compression?Vertical compression means making the y-value smaller for any given value of x, and you can do it by multiplying the entire function by something less than 1. Horizontal stretching means making the x-value bigger for any given value of y, and you can do it by multiplying x by a fraction before any other operations.

Step-by-step explanation:
To find the inverse [tex]f^{-1}(x)[/tex] of a function follow the following steps.
1) Do y = f (x)
[tex]f(x) =y= 2 ^ x + 6[/tex]
[tex]y= 2 ^ x + 6[/tex]
2) Solve the equation for the variable x.
[tex]y= 2 ^ x + 6\\\\y-6 = 2^x\\\\log_2(y-6) = x\\\\x=log_2(y-6)[/tex]
3) exchange the variable y with the variable x
[tex]x=log_2(y-6)\\\\y=log_2(x-6)[/tex]

Distribute
90 = 10y - 2 + 8y + 2

Isolate the variable
y = 15
Then, plug it into XY

Answer:
XY = 24
Step-by-step explanation:
The perimeter of the rectangle is
2(5y - 1) + 2(4y + 1) = 90 ← distribute parenthesis on left side
10y - 2 + 8y + 2 = 90
18y = 90 ( divide both sides by 18 )
y = 5

write an equation that is the slope-intercept form of the equation of the line that passes through (1,2) and is parallel to 4x-2y=6
Answers
Answer:
y=2x
Step-by-step explanation:
If the line is parallel to 4x-2y=6, it means that it has the same slope. So let's first find the slope.
Rearranging, we get
-2y=-4x+6
2y=4x-6
y=2x-3.
So, the slope is 2.
Next, we can use the point slope formula
y-y_1=m(x-x_1)
Substituting, we get
y-2=2(x-1)
y-2=2x-2
y=2x

The height of a cylinder is 4 yards. The volume of the cylinder is 452.16 cubic yards. What is the radius of the cylinder?
Answers
Answer:
r = 5.9984789350480924657633167413961 yards
Step-by-step explanation:
h = 4 yards
V = 452.16 yards Cubed (cubic yards)
V = π[tex]r^{2}[/tex]h
452.16 = π[tex]r^{2}[/tex]*4
divide by pi and 4 and you get approx 35.98
35.981 = [tex]r^{2}[/tex]
the square root of 35.98 is approx 5.9984789350480924657633167413961

In triangle ABC, m A = 25°, m B = 55°, and a = 10.73. Use the law of sines to find b. Round your answer to the nearest tenth.
Answers
Answer:
Option A. [tex]b=20.8\ units[/tex]
Step-by-step explanation:
we know that
Applying the law of sines
[tex]\frac{a}{sin(A)}=\frac{b}{sin(B)}[/tex]
substitute the values and solve for b
[tex]\frac{10.73}{sin(25\°)}=\frac{b}{sin(55\°)}\\ \\ b=10.73*sin(55\°)/sin(25\°)\\ \\b=20.8\ units[/tex]
Answer:
20.8 option A
Step-by-step explanation:
sine law for triangle states that
sin A / a = sin B / b = sin C / c ( equation for sine law )
where m A = 25°
m B = 55°
a = 10.73
b = unknown
from the equation for sine law
sin m A / a = sin m B / b
sin 25° / 10.73 = sin 55° / b
0.4226 / 10.73 = 0.8191 / b
0.0394 = 0.8191 / b equation 2
cross multiply equation 2 becomes
0.0394 b = 0.8191
therefore b = 0.8191 / 0.0394 = 20.789 to the nearest tenth will be 20.8
the width of a rectangular flower bed is 7ft less than the length. The area is 18ftsq. Find the length and the width
Answers
Answer:
width = 2ft and length = 9ft
Step-by-step explanation:
width W = x
length L = x +7
area of a rectangle A = L * W
18 = (x + 7) * x
18 = x² + 7x
x² + 7x -18 =0
solve the equation by factorisation
x² -2x + 9x - 18 =0
x(x - 2) + 9(x - 2) =0
(x - 2)(x + 9) = 0
x = 2 and -9
therefore the width is 2ft because it is positive and the negative value is ignored
the length = 2 + 7 = 9ft
Answer:
width = 2ft and length = 9ft

Factor the polynomial. 3x^3 - 12x^2 + 27x
Answers
Answer:
3x(x^2-4x+9)
Step-by-step explanation:
The polynomial 3x^3 - 12x^2 + 27x is factored by first taking out the greatest common factor of 3x, resulting in the final form of 3x(x^2 - 4x + 9), which cannot be factored further over the real numbers due to a negative discriminant.
To factor the polynomial 3x^3 - 12x^2 + 27x, we look for common factors in each term.
We can see that each term of the polynomial has a factor of 3x. So, we factor out 3x from the polynomial:
3x(x^2 - 4x + 9)
Now, we try to factor the quadratic expression x^2 - 4x + 9. However, this quadratic does not have real roots since the discriminant (b^2 - 4ac) is negative (-4^2 - 4 ×1 ×9 = -20). Therefore, it cannot be factored over the real numbers. Our final factored form of the polynomial is 3x(x^2 - 4x + 9), as we factored out the greatest common factor (GCF).

Tiffani works in a baby shop in which she prints personalized bibs. She uses a probability model to predict that the next customer ordering a white bib would be 30%. For one day, Tiffani gathers data by tallying the the number of customers who order each color in this table.

white 21
grey 9
blue 15
pink 26
Based on her experiment, which statement is true?
Tiffani's prediction is valid. The probability of the next customer ordering a white bib is about 30%.
Tiffani's prediction is not valid. The probability of the next customer ordering a white bib should be about 21% because 21 people ordered white in her data.
Tiffani's prediction is not valid. The next customer ordering a white bib would be the same as any color, so the probability should be about 25%.
There is not enough information to determine the validity of her prediction.
Answers
Answer:
Tiffani's prediction is valid. The probability of the next customer ordering a white bib is about 30%.
Step-by-step explanation:
First you add all of your amounts together

Then to find the probability of the next customer buying a white bib you divide 21 by 71
21/71 = 0.295
