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°.

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°.

Step-by-step explanation:

First, we must find the slope of the line using slope formula*.

[tex]m = \frac{-5 - 1}{-4 - 4} = \frac{-6}{-8} = \frac{3}{4}[/tex]

Second, we now find the y-intercept, or b, using slope-intercept form, the slope we found, and one of the given points.

[tex]1 = \frac{3}{4}(4) + b\\\\1 = 3 + b\\\\-2 = b[/tex]

Lastly, we can now create the equation of the line.

The equation of the line that goes through the given points is C. [tex]y = \frac{3}{4}x - 2[/tex]

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.

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]

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

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]

The solution is, 0.85 is the area under the density curve from 20 to 100.

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.

here, we have,

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.
