-3 is a zero for the polynomial:
x^3 + 7x^2 + 16 x + 12
True or False

Answer:

Step-by-step explanation:

First, you want to simplify so the equation would be x+2≤6 or x≤4

Because you are solving for x you want to graph a vertical line on 4.

Then you shade on the left side of the line because it is less than or equal to. If it were just less then you would do a dashed line on 4 but because it is also equal to 4 then you keep it a solid line.

I recommend using Desmos graphing calculator.

the surface area of the body is approximately 739.72 square inches. first find the area of the two triangles (base and top) using Heron's formula

what is surface area ?

Surface area is the total area of all the faces or surfaces of a three-dimensional object. It is the sum of the areas of all the faces of the object, including the top, bottom, and sides. Surface area is usually measured in square units, such as square inches or square meters.

In the given question,

Let's first find the area of the two triangles (base and top) using Heron's formula:

For the base triangle with side lengths 9, 10, and 13.5:

s = (9 + 10 + 13.5)/2 = 16.25

Area = √(s(s-9)(s-10)(s-13.5)) = 35.44 square inches

For the top triangle, the side lengths are the same, so the area is also 35.44 square inches.

Now, let's find the area of the four sides. We can divide the body into two trapezoids and two triangles. The trapezoids have heights of 9 inches and bases of 9 and 10 inches. The triangles have a base of 13.5 inches and a height of the slant height of the trapezoid, which we can find using the Pythagorean theorem:

h = √(13.5² - (10-9)²) = √(146.25) = 12.1 inches

So, the area of each trapezoid is:

(9/2)*(9+10)*√(146.25 - 9.5²) = 252.28 square inches

And the area of each triangle is:

(1/2)13.512.1 = 81.94 square inches

Finally, the total surface area is the sum of all these areas:

35.44 + 35.44 + 252.28 + 252.28 + 81.94 + 81.94 = 739.72 square inches

Therefore, the surface area of the body is approximately 739.72 square inches.

Answer:

y = 4x+3

Step-by-step explanation:

The equation in point slope form is expressed as y - y0 = m(x-x0)

m is the slope

(x0, y0) is the point on the line

If a line is parallel to y = 4x + 1, the slope of the line m = 4

Substitute m = 4 and the point (-2, -5) into the equation above;

y - (-5) = 4(x - (-2))

y+5 = 4(x+2)

y+5 = 4x+8

y = 4x+8-5

y = 4x + 3

Hence the equation of the line is y = 4x+3

First distribute (8x + 3) into (2^2+ 8x +9)

16x^3 + 64x^2 + 72x + 6x^2 + 24x +27

Then we'll order the pairs from highest to lowest degree

16x^3 + 64x^2 + 6x^2 + 72x + 24x + 27

Then we'll add up the like terms

16x^3 + 70x^2 + 96x + 27

The speed of the flying arrow will be 9 meters/second.

Speed describes how accelerated something or somebody is moving. If you know the distance traveled and the time it took, we can calculate the average speed of an object.

The speed formula is speed = distance/time.

We are given that Cupid's arrow travels 45 meters in 5 seconds.

Therefore, distance = 45 meters

Time=  5 seconds.

Thus, speed = distance/time

Speed = 45/5

Speed  =9

Step-by-step explanation:

The probability that the spinner will land on yellow both times is 1/16.

Probability is the chance of occurrence of a certain event out of the total no. of events that can occur in a given context.

Given, A spinner is divided into 4 equal sections colored red, blue, and green.

So, N(S) = 4 and N(R) = 1, N(B) = 1, N(G) = 1 and N(Y) = 1.

Conditional probability is a term used in probability theory to describe the likelihood that one event will follow another given the occurrence of another event.

As the events of getting yellow both times is independent,

The likelihood that the spinner will hit yellow twice is,

P(Y, Y) = P(Y)×P(Y).

P(Y, Y) = (1/4)×(1/4).

P(Y, Y) = 1/16.

The value of f(5), according to the provided table, is 5.

Evaluating a function means finding the value of an input inserted in a certain function. The input is the domain of the function, and the result is the range of the function. The domain is represented by the x-axis and the range is represented by the y-axis when a function is graphed.

The function f(g(x)) is called a composite function because it is made of two functions. For composite functions, the final value is obtained by performing two steps. The first step is finding the value of the function on the inside. Then, the value of the inside function is used, and the outer function is calculated for that value. So we first have to find the value of g(3), meaning that x is equal to 3.

According to the provided table for the values of x and g(x), when the value of x is 3, the value of g(x) is 6. This is the first step. The subsequent step is finding the value of the f(x) function. The x of this function is the value of g(x), which is 6. The value of f(5), according to the provided table, is 5.

Answer:

The number must be greater than 6.7. Thus, the sum will be negative.

For example, the number could be 7.

6.7 - 7 = -0.3

The number can be in the range -  x ∈ (- ∞ , - 6.7)

We have - the sum of 6.7 and a number is negative.

We have to determine the possible value of that number.

For f(x) to be negative -

f(x) < 0

2x + 10 < 0

2x < - 10

x < - 5

x ∈ (- ∞ , - 5)

According to the question, we have - the sum of 6.7 and a number is negative.

Now -

6.7 + x < 0

x < 6.7

x ∈ (- ∞ , - 6.7)

Hence, the number can be in the range -  x ∈ (- ∞ , - 6.7).
