Answer:

The coefficient of the squared expression in the parabola equation is [tex]a=4[/tex]

Step-by-step explanation:

The equation of a parabola in its vertex form is:

[tex]y = a(x-h) ^ 2 + k[/tex]

Where the vertex of the parabola is the point (h, k)

a is the ceoficiente of the term to the square.

We need to find the equation of a parabola that has its vertex in the point:

(-5, -2)

So:

[tex]h = -5\\\\k = -2[/tex]

Therefore the equation is:

[tex]y = a(x - (-5)) ^ 2 -2\\\\y = a(x + 5) ^ 2 -2[/tex]

We know that the point (-4, 2) belongs to this parable. Then we can find the value of a by replacing the point in the equation of the parabola

[tex](2) = a((-4) + 5) ^ 2 -2\\\\2 = a(1) ^ 2 -2\\\\2 = a -2\\\\a = 4[/tex]

Finally the coefficient is a = 4

Answer:

The answer is 4

Step-by-step explanation:

This is the correct answer

Correct option is C. The independent variable in the equation y = 10x is 'x', which represents the number of questions answered correctly on the exam.

In the equation y = 10x, the independent variable is the variable that you have control over or can set the value of freely, which in this context is the number of questions answered correctly on the exam represented by 'x'. The dependent variable, represented by 'y', is the total number of points you score on the exam, which depends on the number of questions you answered correctly. Therefore, the correct answer to the question is C) The number of questions answered correctly on the exam.

Answer: [tex]\frac{70}{3}[/tex]

Step-by-step explanation:

Given a fraction [tex]\frac{a}{b}[/tex] and a fraction [tex]\frac{c}{d}[/tex], you can find the product by multiplying the numerator of the first fraction by the numerator of the second fraction and the denominator of the first fraction by the denominator of the second one:

[tex]\frac{a}{b}*\frac{c}{d}=\frac{ac}{bd}[/tex]

Therefore, knowing this you can find the product of the fractions [tex](\frac{5}{3})(\frac{2}{3})(\frac{21}{1})[/tex]:

 [tex](\frac{5}{3})(\frac{2}{3})(\frac{21}{1})=\frac{5*2*21}{3*3*1}=\frac{210}{9}[/tex]

And finally you need to reduce the fraction:

[tex]=\frac{70}{3}[/tex]

Answer:

Final answer is [tex]\frac{70}{3}[/tex].

Step-by-step explanation:

Given expression is :

[tex]\left(\frac{5}{3}\right)\cdot\left(\frac{2}{3}\right)\cdot\left(\frac{21}{1}\right)[/tex]

Now we need to find their product. In other words simplify it

We can multiply numerator with numerator. Then denominator with denominator

[tex]\left(\frac{5}{3}\right)\cdot\left(\frac{2}{3}\right)\cdot\left(\frac{21}{1}\right)[/tex]

[tex]=\frac{5\cdot2\cdot21}{3\cdot3\cdot1}[/tex]

[tex]=\frac{210}{9}[/tex]

[tex]=\frac{70}{3}[/tex]

So the final answer is [tex]\frac{70}{3}[/tex].

If both machines are working at once, 200 tshirts (100 in each machine) could be made in 100 minutes, if 200 shirts can be made in machine 1 in 50 minutes, it will take 25 minutes to make 100. machine b takes 150 minutes per each 200, 150 divided by two is 75. 75 + 25 = 100 minutes

It would work better just to use machine one and take 50

minutes, but i dont think thats an answer choice.

edit: i think from the choices your answer would be: 37.5 as if both machines run at once more tshirts can be made

Answer:

Step-by-step explanation:

Let b and g represent the number of boys and the number of girls respectively.

Then b + g = 22 (students), and g = b + 12.

Substituting b + 12 for g in b + g = 22 yields:

b + (b + 12) = 22

or:

2b + 12 = 22, or 2b = 10, so that b = 5.

Then g = b + 12 = 5 + 12 = 17.

There are 17 girls and 5 boys.

Question 1:

For this case, let the variable "x" be the number of girls in the classroom. Let the variable "y" be the number of boys in the classroom.

We propose the equations:

[tex]x + y = 22\\x = y + 12[/tex]

We substitute the second equation in the first:

[tex]y + 12 + y = 22\\2y = 22-12\\2y = 10\\y = 5[/tex]

So, in the classroom there are 5 boys.

[tex]x = 5 + 12\\x = 17[/tex]

So, there are 17 girls.

Answer:

5 guys

17 girls

Question 2:

For this case we have to:

Let x be the variable that represents the amount of money Jamie has.

Let y the variable that represents the amount of money that Kristen has

We have to:

[tex]x = 2y\\x + y = 36[/tex]

We substitute the first equation in the second:

[tex]2y + y = 36\\3y = 36\\y = \frac {36} {3}\\y = 12[/tex]

Looking for the value of x:

[tex]x = 2 (12)\\x = 24[/tex]

Answer:

So, Jaime you have $ 24 and Kristen you have $ 12.

Question 3:

For this case we have to:

Let "x" be the variable that represents the number of dogs in the Pet Stop.

Let "y" be the variable that represents the number of cats in the Pet Stop.

We have to:

[tex]x + y = 15\\4x = y[/tex]

We substitute the second equation in the first:

[tex]x + 4x = 15\\5x = 15\\x = \frac {15} {5}\\x = 3[/tex]

We look for the value of y:

[tex]y = 4x\\y = 4 (3)\\y = 12[/tex]

So, there are 12 cats and 3 dogs.

Answer:

12 cats

3 dogs

Answer:Classifying Polynomials. Polynomials can be classified two different ways - by the number of terms and by their degree. A monomial has just one term. For example, 4x2 .Remember that a term contains both the variable(s) and its coefficient (the number in front of it.)

Step-by-step explanation:Hope this helps. Please name me brainliest

The answer is:

⇨ look at its highest exponent

Work/explanation:

To classify polynomials by their degree, look at the highest exponent of the polynomial.

For instance, if we have [tex]\rm{x^2+2x}[/tex] then we have a second-degree binomial.

(binomial because we have 2 terms)

The answer is:

The distance between the two jets is 63.5 mi.

From the statement we know that the first jet is located 56 mi due to the east city while the second jet is located 30 mi due to the north, so, we can calculate the distance between the two jets using the Pythagorean Theorem.

The Pythagorean Theorem states that:

[tex]c^{2}=a^{2} +b^{2}[/tex]

So,

[tex]Distance=\sqrt{(Jet_{1}Location)^{2}+(Jet_{2}Location)^{2}}\\\\Distance=\sqrt{(56mi)^{2}+(30mi)^{2}}=\sqrt{3136mi^{2}+900mi^{2}} \\\\Distance=\sqrt{3136mi^{2}+900mi^{2}}=\sqrt{4036mi^{2}}=63.5mi[/tex]

Hence, the distance between the two jets is 63.5 mi.

That is a cuboid.

Cuboids have 8 vertices

As we are looking at the given shape, we have identified that it has 8 vertices.

A cuboid has three pairs of opposite faces. Each pair consists of two congruent rectangles that are parallel to each other. For instance, let's label the length, width, and height of the cuboid as "a," "b," and "c," respectively.

Length faces: These are the two large faces on the opposite sides of the cuboid, each measuring "a" units in length and "c" units in height. They contribute 4 vertices, two on the top edge and two on the bottom edge.

Width faces: These are the two smaller faces on the opposite sides, each measuring "b" units in width and "c" units in height. Like the length faces, they also contribute 4 vertices.

Height faces: These are the top and bottom faces of the cuboid, each measuring "a" units in length and "b" units in width. They contribute 4 vertices as well.

Now, it's essential to note that each vertex is a point where three edges meet. A cuboid has three edges meeting at each of its eight vertices. However, the four vertices on the top of the cuboid are not the same as the four vertices on the bottom; they belong to different faces. Hence, we cannot count them twice.

Thus, a cuboid has a total of 8 vertices.

Multiply the bracket by 1/2

1/2(2n +6)

cross out 2 and 2n and divide by 2.

cross out 6 and 2 and divide by 2

n+3

Answer is n+3

Distribute 1/2 into (2n+6): 1/2 * 2n + 1/2 * 6. Simplify: n + 3. The equivalent expression is n + 3.

Let's break down the process step by step:

Given expression:[tex]\( \frac{1}{2}(2n+6) \)[/tex]

1. Distribute [tex]\( \frac{1}{2} \)[/tex]into the parentheses:

  We multiply each term inside the parentheses by [tex]\( \frac{1}{2} \):[/tex]

  [tex]\( \frac{1}{2} \times 2n + \frac{1}{2} \times 6 \)[/tex]

2. Simplify each term:

  a. [tex]\( \frac{1}{2} \times 2n \):[/tex]

     The [tex]\( \frac{1}{2} \)[/tex] and the [tex]\( 2 \)[/tex] cancel out, leaving [tex]\( n \).[/tex]

  b. [tex]\( \frac{1}{2} \times 6 \):[/tex]

     Multiply [tex]\( \frac{1}{2} \) by \( 6 \) to get \( 3 \).[/tex]

3. Combine the simplified terms:

  Add the simplified terms together:

  [tex]\( n + 3 \)[/tex]

So, the expression equivalent to [tex]\( \frac{1}{2}(2n+6) \) is \( n + 3 \).[/tex]

Step-by-step explanation:

The given function is

[tex]g(x)=\frac{x^2-5}{3x}[/tex]

To find g(n-7), we substitute x=n-7 to obtain;

[tex]g(n-7)=\frac{(n-7)^2-5}{3(n-7)}[/tex]

Expand the parenthesis to obtain;

[tex]g(n-7)=\frac{n^2-14n+49-5}{3n-21}[/tex]

Simplify:

[tex]g(n-7)=\frac{n^2-14n+44}{3n-21}[/tex]

Answer:

23

Step-by-step explanation:

Basically, (f o g)(1) is saying f(g(1))

So let's plug in 1 into the g(x) equation.

[tex]g(1)=2(1)-6 \\ \\ g(1)=2-6 \\ \\ g(1)=-4[/tex]

Now we can plug in -4 into the f(x) equation.

[tex]f(-4)=-4(-4)+7 \\ \\ f(-4)=16+7 \\ \\ f(-4)=23[/tex]

23

Step-by-step explanation:

This is a problem of composition of function. We can define this as follows:

[tex]The \ \mathbf{composition} \ of \ the \ function \ f \ with \ the \ function \ g \ is:\\ \\ (f \circ g)(x)=f(g(x)) \\ \\ The \ domain \ of \ (f \circ g) \ is \ the \ set \ of \ all \ x \ in \ the \ domain \ of \ g \\ such \ that \ g(x) \ is \ in \ the \ domain \ of \ f[/tex]

So [tex](f.g)(x)=f(g(x))=h(x)[/tex]:

[tex]h(x)=-4(2x-6)+7 \\ \\ h(x)=-8x+24+7 \\ \\ h(x)=-8x+31[/tex]

Therefore:

[tex]h(x)=f(g(1))=-8(1)+31=23[/tex]

Answer:

Step-by-step explanation:

We have three triangles with base b = 9yd and height h = 10yd, and one triangle in the base of pyramid with base b = 9yd and height h = 7.8yd.

The formula of an area of a triangle:

[tex]A_\triangle=\dfrac{bh}{2}[/tex]

Substitute:

[tex]LA=4\cdot\dfrac{(9)(10)}{2}=(2)(90)=180\ yd^2\\\\B=\dfrac{(9)(7.8)}{2}=(9)(3.9)=35.1\ yd^2\\\\SA=B+LA\to SA=180+35.1=215.1\ yd^2[/tex]

This is a quadratic equation. You have to factor it.

You have to find two numbers that meet the following requirement:

-When multiplied, is equal to -18.

-When added, is equal to 3.

The two numbers are 6 and -3.

Now factor it:

(x + 6)(x - 3)

So x = -6 or x = 3
