Which of the following equations has roots x=−2, x=3 (multiplicity 2), and x=1, and passes through the point (0,-18)?

In the case above, option b is correct: Marcelina spends the intended amount of money but she bought more than she did intended amount of corn

She  buy 50kg of corn in total

So the equation will be:

C= (20, 50) = 20 white, 50 yellow

But 30 while and 20 yellow is needed.

Since  C = 20 +50 = 70 corns

While 30 + 20 = 50 corns.

This implies that she spends the intended amount of money but she bought more than she did intended amount of corn and as such, option b is correct.

If the area is 90 square units. Then the dimension of the rectangle will be 5 units and 18 units.

Let L be the length and W be the width of the rectangle.

Then the area of the rectangle will be

Area of the rectangle = L×W square units

The width of a rectangle is 13 units less than the length.

If the area is 90 square units.

W = L – 13

Then we have

                           90 = L(L – 13)

         L² – 13L – 90 = 0

L² – 18L + 5L – 90 = 0

L(L – 18) + 5(L – 18) = 0

         (L – 18)(L + 5) = 0

                             L = -5, 18

Then the width will be

W = 18 – 13

W = 5 units

Then the dimension of the rectangle will be 5 units and 18 units.

The time to hit the ground is 1.9 seconds

The height equation is given as:

d = -16t^2 + h0

A stone thrown from 60 feet has an initial height of 60.

This means that:

h0 = 60

So, we have:

d = -16t^2 + 60

When the stone hits the ground, d = 0

So, we have:

-16t^2 + 60 = 0

Evaluate the like terms

-16t^2 = -60

Divide by -16

t^2 = 3.75

Evaluate the square root

t = 1.9

The altitude of an object with respect to a reference plane or point is termed its height. This includes all parts of the object that add up to its height. Therefore, the height of the wall would be 100.5 inches.

The height of a given object implies the altitude of the object from a reference plane or point.

Therefore given that concrete blocks are 8 inches, then;

total height of mortar required to hold each concrete block = 3/8 inches

Thus, since there are 12 concrete blocks, then 12 sections of mortar would be required to hold 12 blocks starting from the ground.

So that;

total height of mortar required = 3/8 x 12

                                         = 4.5 inches

Total height of all concrete blocks required = 12 x 8

                                                             = 96 inches

Therefore, the height of the wall of 12 courses of concrete blocks = 96 + 4.5

                                                   = 100.5 inches

Step-by-step explanation:

I believe so because the 20 pole took away six so im guessing the 41 pole will to the same

The length of the shadow cast by the 14-foot pole is 8.4 shadows.

We have,

From the figure given,

The two triangles are similar since the corresponding sides and angles are given equal.

This means,

The ratio of the corresponding sides is equal.

So,

20/14 = 12/x _______(1)

Where x is the length of the shadow cast by the 14-foot pole.

Now,

Solving for x from (1).

20/14 = 12/x

Divide 12 on both sides.

20 / (14 x 12) = 1/x

20/168 = 1/x

Cross multiply.

x = 168/20

x = 8.4 shadow.

The length of the shadow cast by the 14-foot pole is 8.4 shadows.

The function whose graph is in the linear straight line then that function is considered a linear function.

An example of this is 2x+3

An exponential function is a model or a relationship in which there is a constant change in the independent variable that gives the same change in proportionality.

The given function is not showing a linear growth which means there is no straight line so the function will be exponential.

When x increases by 1 unit then the growth factor will be 3/1 = 3

Step-by-step explanation:

because cos0 = b/h

so cos0 = 8/15

Using simpler trigonometric identities, the given identity was proven below.

Remember that:

[tex]sec(x) = \frac{1}{cos(x)} \\\\tan(x) = \frac{sin(x)}{cos(x)}[/tex]

Then the identity can be rewritten as:

[tex]sec^4(x) - sen^2(x) = tan^4(x) + tan^2(x)\\\\\frac{1}{cos^4(x)} - \frac{1}{cos^2(x)} = \frac{sin^4(x)}{cos^4(x)} + \frac{sin^2(x)}{cos^2(x)} \\\\[/tex]

Now we can multiply both sides by cos⁴(x) to get:

[tex]\frac{1}{cos^4(x)} - \frac{1}{cos^2(x)} = \frac{sin^4(x)}{cos^4(x)} + \frac{sin^2(x)}{cos^2(x)} \\\\\\\\cos^4(x)*(\frac{1}{cos^4(x)} - \frac{1}{cos^2(x)}) = cos^4(x)*( \frac{sin^4(x)}{cos^4(x)} + \frac{sin^2(x)}{cos^2(x)})\\\\1 - cos^2(x) = sin^4(x) + cos^2(x)*sin^2(x)\\\\1 - cos^2(x) = sin^2(x)*sin^2(x) + cos^2(x)*sin^2(x)[/tex]

Now we can use the identity:

sin²(x) + cos²(x) = 1

[tex]1 - cos^2(x) = sin^2(x)*(sin^2(x) + cos^2(x)) = sin^2(x)\\\\1 = sin^2(x) + cos^2(x) = 1[/tex]

Thus, the identity was proven.

The measure of arc BEC in circle D is 134°

From the question, we are to determine the measure of arc BEC

Measure of arc BEC = 2 × m∠BAC

First, we will determine the measure of angle ACB

From one of the circle theorems,

The angle subtended by an arc of a circle is twice the angle it subtends anywhere on the circle's circumference

∴ m∠ACB = 1/2 × 76°

m∠ACB = 38°

Then,

m∠BAC + m∠ACB + m∠ABC = 180° (Sum of angles in a triangle)

m∠BAC + 38° + 75° = 180°

m∠BAC + 113° = 180°

m∠BAC  = 180°- 113°

m∠BAC = 67°

Then,

Measure of arc BEC = 2 × m∠BAC

Measure of arc BEC = 2 × 67°

Measure of arc BEC = 134°

Hence, the measure of arc BEC is 134°

Make a graph with bug repellent as x, and bug bites as y

Step-by-step explanation:

This just makes the most sense to me, depending on how many people use bug repellent, how many bug bites they get.

The sum is given by -  f(y) = 4(y -1).

We have the following expression -

(y + 5) + (3y - 9)

We have to evaluate the above sum.

Now -

f(x) + g(x) = 3x + 9 - (6 - x)  

f(x) + g(x) = 3x + 10 - 6 + x

f(x) + g(x) =  4x + 4

f(x) + g(x) = 4(x + 1)

According to the question, we have -

(y + 5) + (3y - 9)

Assume that the sum is represented by the function f(y).

Solving, we get -

f(y) = y + 5 + 3y - 9

f(y) = y + 3y + 5 - 9

f(y) = 4y - 4

f(y) = 4(y - 1)

Hence, the sum is given by -  f(y) = 4(y -1).
