THISS IS SURGENT PLSSS Form a polynomial whose zeros and degree are given.
Zeros: -7, multiplicity 1 3;multiplicity 2; degree 3
Type a polynomial with integer coefficients and a leading coefficient of 1 in the box below.
Answer:
The polynomial is x^3-x^2-33x+63
Step-by-step explanation:
Here, we want to find a polynomial of degree 3 with the given roots
-7 with a multiplicity of 1 and 3 with a multiplicity of 2
if x = -7
x + 7 is a root
if x = 3
x -3 is a root
Since the multiplicity of this is 2, we have x-3 twice
The complete polynomial is;
(x-3)(x-3)(x+7)
= x^2-6x+9(x + 7)
= x(x^2-6x+9) + 7(x^2-6x+9)
= x^3-6x^2 + 9x+7x^2-42x+63
= x^3-x^2-33x+63

A contractor brought 10.8 ft^2 of sheet metal. She has used 3.7 ft^2 so far and has $127.80 worth of sheet metal remaining. The equation 10.8x-3.7x=127.8 represents how much sheet metal is remaining and the cost of the remaining amount. How much does sheet metal cost per square foot?
Answer:
[tex]\$18[/tex]
Step-by-step explanation:
Let the cost of sheet metal per square feet be [tex]x[/tex]
Amount of sheet metal bought is [tex]10.8\ \text{ft}^2[/tex]
Amount of sheet metal used is [tex]3.7\ \text{ft}^2[/tex]
Remaining value of the sheet metal is [tex]\$127.8[/tex]
So we get the equation
[tex]10.8x-3.7x=127.8\\\Rightarrow 7.1x=127.8\\\Rightarrow x=\dfrac{127.8}{7.1}\\\Rightarrow x=18[/tex]
So, cost of sheet metal per square feet is [tex]\$18[/tex].

brooke found the equation of the line passing through the points (-7,25) and (-4,13) in slope-intercept form as follows
Answer:
The equation of the line passing through the points (-7,25) and (-4,13) in slope-intercept form is [tex]\mathbf{y=-4x-3}[/tex]
Step-by-step explanation:
Equation of line passing through the points (-7,25) and (-4,13) in slope-intercept form.
The general equation of slope-intercept form is: [tex]y=mx+b[/tex]
First we need to find slope
The formula used for finding slope is: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
We are given: [tex]x_1=-7, y_1=25, x_2=-4, y_2=13[/tex]
Putting values in formula and finding slope
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{13-25}{-4-(-7)}\\Slope=\frac{13-25}{-4+7}\\Slope=\frac{-12}{3}\\Slope=-4[/tex]
So, slope m= -4
Now finding y-intercept
Using slope m=-4 and point (-7,25) we can find y-intercept
[tex]y=mx+b\\25=-4(-7)+b\\25=28+b\\b=25-28\\b=-3[/tex]
So, y-intercept b =-3
Now, the equation of required line having slope m=-4 and y-intercept b=-3 is:
[tex]y=mx+b\\y=-4x-3[/tex]
So, the equation of the line passing through the points (-7,25) and (-4,13) in slope-intercept form is [tex]\mathbf{y=-4x-3}[/tex]

B.)g-1( x) =5/2 x + 2
C.)g-1( x) = - 2/5x + 2
D.)g-1( x) =5/2 x + 5
Answer:
D
Step-by-step explanation:
the slope =
[tex] \frac{0 - ( - 2)}{5 - 0} = \frac{2}{5} [/tex]
y =mx+b
m = slope
when x = 0 , y = -2
y =(2x/5)-2
x =(2y/5)-2
x+2 = (2y/5)
5x+10 = 2y
y =(5x/2)+5 = g-1(x)

A projectile is thrown upward off a 130ft cliff at a velocity of 15ft/second. How long before it reaches a height of 25ft?
Answer:
The time taken for the projectile to reach the given height is 1.2 s.
Step-by-step explanation:
Given;
height of travel, h = 25 ft
initial velocity of the projectile, u = 15 ft/s
The time taken for the projectile to travel a height of 25 ft is given by the following kinematic equation;
h = ut + ¹/₂gt²
25 = 15t + ¹/₂(9.8)t²
25 = 15t + 4.9t²
4.9t² + 15t - 25 = 0
solving the quadratic equation, we will have the following solution of t;
t = 1.2 s
Therefore, the time taken for the projectile to reach the given height is 1.2 s.

The solution is, 0.85 is the area under the density curve from 20 to 100.
What is area ?Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

given that,
Suppose the sample space for a continuous random variable is 0 to 100. If the area under the density curve for the variable from 0 to 20 is 0.15
The area under the density curves for the continuous random variables always add up to unity.
Thus, the area under the density curve from 20 to 100 is ;
1 - 0.15
which is;
1 - 0.15
= 0.85
Hence, The solution is, 0.85 is the area under the density curve from 20 to 100.

Answer:
MNI = 135º
Step-by-step explanation:
From the picture, we have the two internal angles as [tex]6x[/tex] and [tex]15x-12[/tex]. The third, the angle ∠MNL is 180 - 19x-2. Therefore,
[tex]15x-12+6x+(180-19x-2)=180[/tex]
So,
[tex]15x-12+6x+180-19x-2=180[/tex]
[tex]15x-14+6x-19x=0[/tex]
[tex]2x=14[/tex]
[tex]x=7[/tex]
Finally,
∠MNI = 19x+2 ⇒ ∠MNI = 19(7)+2 ⇒ ∠MNI = 135º
The value of the variable 'x' is 7. Then the measure of the angle ∠MNI will be 131°.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.
The exterior angle of a triangle is almost always equal to the addition of the interior and opposing interior angles. The term "external angle property" refers to this feature.
Then the equation is given as,
∠NLM + ∠LMN = ∠MNI
6x + 15x - 12 = 19x + 2
2x = 14
x = 7
Then the measure of the angle ∠MNI is calculated as,
∠MNI = 19 (7) - 2
∠MNI = 133 - 2
∠MNI = 131°
The value of the variable 'x' is 7. Then the measure of the angle ∠MNI will be 131°.

(Please this is URGENT!) On a computer screen, Jennifer just created a triangular design of a banner with vertices at A(-4,3), B(-1,5) and C(-1,2). She can use the computer software to perform transformations on this design.
Which sequence of two transformations could she perform so that the transformed vertices become A'(4,-5), B'(7,-7), and C'(7,-4)?
a. translating 6 units down, followed by translating 8 units to the right
b. reflecting about the line y = -2, followed by translating 8 units to the right
c. reflecting about the line y = -1, followed by reflecting about the y-axis
d. reflecting about the line y = -1, followed by translating 8 units to the right
Answer:
The correct option is;
d. Reflecting about the line y = -1, followed by translating 8 units to the right
Step-by-step explanation:
The coordinates of the vertices of the banner Jane created = A(-4, 3), B(-1, 5) and C(-1, 2)
By reflecting across the line y = -1, we get
A(-4, 3) by reflection across the line y = -1 gives A(-4, -5)
B(-1, 5) by reflection across the line y = -1 gives B(-1, -7)
C(-1, 2) by reflection across the line y = -1 gives C(-1, -4)
By translating 8 units to the right get
A(-4, 3) by translation 8 units right gives A prime (4, -5)
B(-1, 5) by translation 8 units right gives B prime (7, -7)
C(-1, 2) by translation 8 units right gives C prime (7, -4)
Therefore, the two transformation that she could perform so that the transformed vertices become A prime (4, -5), B prime (7, -7), and C prime (7, -4) are;
1) Reflection across the line y = -1
2) An horizontal translation 8 units to the right get.
Transformation involves changing the size and position of a shape.
The sequence of two transformations are: (d). reflecting about the line y = -1, followed by translating 8 units to the right
The coordinates of ABC are given as:
[tex]\mathbf{A =(-4,3)}[/tex]
[tex]\mathbf{B =(-1,5)}[/tex]
[tex]\mathbf{C =(-1,2)}[/tex]
First, the coordinates of ABC are reflected across the line [tex]\mathbf{y =-1}[/tex]
The transformation rule is:
[tex]\mathbf{(x,y) \to (x,-y -2 \times 1)}[/tex]
So, we have:
[tex]\mathbf{A' = (-4,-3 -2 \times 1)}[/tex]
[tex]\mathbf{A' = (-4,-5)}[/tex]
[tex]\mathbf{B' =(-1,-5 - 2 \times 1)}[/tex]
[tex]\mathbf{B' =(-1,-7)}[/tex]
[tex]\mathbf{C' =(-1,-2 -2 \times 1)}[/tex]
[tex]\mathbf{C' =(-1,-4)}[/tex]
Next, the shape is translated 8 units right.
The rule of this transformation is:
[tex]\mathbf{(x,y) \to (x + 8, y)}[/tex]
So, we have:
[tex]\mathbf{A" = (-4 + 8, -5)}[/tex]
[tex]\mathbf{A" = (4, -5)}[/tex]
[tex]\mathbf{B" =(-1+8,-7)}[/tex]
[tex]\mathbf{B" =(7,-7)}[/tex]
[tex]\mathbf{C" =(-1+8,-4)}[/tex]
[tex]\mathbf{C" =(7,-4)}[/tex]
Hence, the sequence of two transformations are:
(d). reflecting about the line y = -1, followed by translating 8 units to the right
