Answer:

Can not be factorized further

Step-by-step explanation:

Here we are asked to factorize the expression [tex]3x^2+x+7[/tex]

In order to factorize a quadratic polynomial , we have to follow the following steps.

step 1. We have to find the product of coefficient of [tex]x^2[/tex] and the constant term. In this case the coefficient of [tex]x^2[/tex] is 3 and constant term is 7. Hence the product is 3*7=21

Step 2: Now we have to find all the possible factors of this product. In our case the factors will be

21=1*21

21=3*7

Step 3: We have to select one pair of those factors such that their sum or difference is equal to the coefficient of middle term that is [tex]x[/tex] . In this case it is 1. And we can see that in our polynomial , none of the pair gives you 1 either as sum or difference.

As there does not exist any such pair , it can not be further factorize.

Answers

Answer:

The triangles are similar by AA Similarity Postulate

Step-by-step explanation:

we know that

In the triangle ABC

m∠CAB=65°

m∠ABC=m∠CAB

so

m∠ABC=65°

Find the measure of angle ACB

Remember that

The sum of the internal angles in a triangle must be equal to 180 degrees

so

m∠ACB+m∠ABC+m∠CAB=180°

substitute the values

m∠ACB+65°+65°=180°

m∠ACB=180°-130°=50°

In the triangle DEF

m∠FDE=m∠CAB=65°

m∠DFE=50°

Find the measure of angle DEF

Remember that

The sum of the internal angles in a triangle must be equal to 180 degrees

so

m∠DEF+m∠FDE+m∠DFE=180°

substitute the values

m∠DEF+65°+50°=180°

m∠DEF=180°-115°=65°

therefore

m∠CAB=m∠FDE=65°

m∠ABC=m∠DEF=65°

m∠ACB=m∠DFE=50°

so

The three internal angles of the triangles are congruent

therefore

The triangles are similar by AA Similarity Postulate

how do you find x? i know the answer is 8.9 (bc of answer key) but how do i get to that?

Answers

Answer:

x = 8.9

Step-by-step explanation:

We can see in the problem that the diameter is 37.8.

Radius is 1/2 of the diameter.

d = 2r

So in this problem r = 37.8/2 or r = 18.9.

Then you can see that the given side of the triangle is 10.

Since we know that that line is also the radius since it goes from the edge of the circle to the center, we can just subtract 10 from 18.9 to get 8.9.

What is the equation of the horizontal line through (-4,6)

Answers

Answer:

y = 6

Step-by-step explanation:

We are to find the equation of the horizontal line which passes through the point (-4,6).

Since the line is horizontal so the slope will be zero and the equation will be [tex] y = c [/tex] for some constant [tex] c [/tex].

We know that the line passes through the point (-4,6) so the constant [tex] c [/tex] will be 6 at all points on the line.

Therefore, the equation of the horizontal line will be y = 6.

ANSWER

[tex]y = 6[/tex]

EXPLANATION

The equation of a horizontal line passing through:

[tex](x_1,y_1)[/tex]

is given by

[tex]y=y_1[/tex]

The equation of the horizontal line through (-4,6) is

Angle θ is in standard position. The terminal side of the angle passes through the point (5/13,12/13 ) on the unit circle. Find cscθ.

Answers

Answer:

cscФ = 13/12

Step-by-step explanation:

∵ The terminal side of the angle Ф passes through point (5/13 , 12/13)

∵ x = 5/13 and y = 12/13

∵ x = cosФ and y = sinФ

∴ cosФ = 5/13

∴ sinФ = 12/13

∵ cscФ = 1/sinФ

∴ cscФ = 1 ÷ 12/13 = 13/12

Answers

Answer:

b

Step-by-step explanation:

The volume (V) of the triangular prism is

V = area of triangular end × length

area of triangle = [tex]\frac{1}{2}[/tex] × 3.4 × 2.5 = 4.25 in², hence

V = 4.25 × 4.8 = 20.4 in³ → b

Answer: B

Step-by-step explanation:

The volume of a triangular prism can be achieved by the equation:

[tex]V=\frac{1}{2} *l*w*h[/tex]

similar to finding the volume of a regular right triangle, where you have:

[tex]a=\frac{1}{2} b*h[/tex]

Here all you are adding is the dimension of depth by multiplying that depth (l) by the equation for the area.

larry earns $20.25 per hour plus 8% of his sales which of the following equations represents toms earrings E when he works x hours and has a total of y sales in dollars

Answers

E=20.25x+y is the equation

Final answer:

Larry's earnings, represented by E, when he works x hours and has y dollars in sales, is calculated by his hourly wage ($20.25 per hour) plus an 8% commission on his sales, which results in the equation E = 20.25x + 0.08y.

Explanation:

To calculate Larry's earnings E based on his hourly wage and sales commission, we need to consider both parts of his earnings: his hourly rate and his commission rate. The equation that represents Larry's earnings when he works x hours and has a total of y sales in dollars will include the hourly earnings plus a percentage of his sales.

Larry earns $20.25 per hour, so his earnings from hours worked would be 20.25 times the number of hours worked, which is 20.25x.

Additionally, Larry earns a commission of 8% on his sales. To calculate this, you need to convert the percentage to a decimal by dividing by 100 (8% becomes 0.08) and then multiply by the total sales y, resulting in 0.08y.

The total earnings E would therefore be the sum of his hourly earnings and his sales commission, which gives us the equation E = 20.25x + 0.08y.

Sarah Drew a parallelogram that is not a rectangle what is the greatest number of right angles Sarah's parallelogram can have ​

Answers

I think the answer is 2

Final answer:

A parallelogram is a quadrilateral with parallel and equal sides, but it does not necessarily have any right angles. The greatest number of right angles a parallelogram can have is two, which occurs when the parallelogram is a rectangle.

Explanation:

A parallelogram is a quadrilateral with opposite sides that are parallel and equal in length. In a parallelogram, the opposite angles are also equal. However, a parallelogram is not required to have any right angles, and in fact, most parallelograms do not have any right angles.

The greatest number of right angles a parallelogram can have is two. This would occur when the parallelogram is a rectangle, which is a special type of parallelogram. A rectangle has opposite sides that are parallel and equal in length, and all four angles are right angles, measuring 90 degrees each.

Therefore, the answer to Sarah's question is that the greatest number of right angles her parallelogram can have is two.

triangle STV has sides with lengths of 7, 11, and 14 units. Determine whether this is a right triangle.​

Answers

Final answer:

By applying the Pythagorean theorem, we find that the sum of the squares of the two shorter sides of triangle STV (7 and 11) is not equal to the square of the longest side (14). Therefore, triangle STV is not a right triangle.

Explanation:

To determine if triangle STV with sides of 7, 11, and 14 is a right triangle, we can apply the Pythagorean theorem, a² + b² = c², where c is the hypotenuse (the longest side of the triangle) and a and b are the other two sides. For triangle STV, assume that the side with a length of 14 units is the hypotenuse, and the sides with lengths of 7 and 11 units are the other two sides.

Now, let's calculate:

a² = 7² = 49

b² = 11² = 121

a² + b² = 49 + 121 = 170

c² = 14² = 196

Since 170 does not equal 196, the sums of the squares of the sides do not equal the square of the hypotenuse. Therefore, triangle STV is not a right triangle.

If f(x) = –2x + 7 and g(x) = x2 – 2, what is [f o g](3)?

Answers

Answer:

[tex](f\circ g)(3)=-7[/tex]

Step-by-step explanation:

The given functions are;

[tex]f(x)=-2x+7[/tex]

and

[tex]g(x)=x^2-2[/tex]

We need to first of all find [tex](f\circ g)(x)[/tex]

[tex](f\circ g)(x)=f(g(x))[/tex]

[tex](f\circ g)(x)=f(x^2-2)[/tex]

[tex](f\circ g)(x)=-2(x^2-2)+7[/tex]

[tex](f\circ g)(x)=-2x^2+4+7[/tex]

[tex](f\circ g)(x)=-2x^2+11[/tex]

We now plug in x=3

[tex](f\circ g)(3)=-2(3)^2+11[/tex]

[tex](f\circ g)(3)=-18+11[/tex]

[tex](f\circ g)(3)=-7[/tex]

$800 is deposited in an account that pays 9% annual interest compounded annually. Find the balance after four years

Answers

Answer:

$1,129.27

Step-by-step explanation:

Compounded interest formula is

[tex]A=P(1+\frac{r}{n})^{nt}[/tex]

Where [tex]A[/tex] is the final amount, [tex]P[/tex] is the principal, [tex]r[/tex] is the anual interest in decimal, [tex]n[/tex] is the numer of compounded periods in one year and [tex]t[/tex] is the time in years.

[tex]P=\$800\\r=0.09\\n=1\\t=4[/tex]

Notice that [tex]n=1[/tex], because the interest is compounded anually, if the interest is compounded, then [tex]n=12[/tex], because there would be 12 compound periods in one year.

Then, we replace all these vaules in the formula

[tex]A=P(1+\frac{r}{n})^{nt}\\A=800(1+\frac{0.09}{1})^{1(4)}=800(1.09)^{4}\\ A=1,129.26[/tex]

Therefore, after 4 years, the amount would be $1,129.27.
