where is sandy mistake ive been trying for 30 mintues and still cant find it im not very good at math please help

Answer:

Below in bold.

Step-by-step explanation:

a) 52 = 5.2 * 10 so the result is 348.4 * 10 = 3484.

b) 6.7 is a tenth of 67 so the result is  348.4 / 10 = 34.84.

c) 348.4  - 52 = 296.4.

Answer:

Step-by-step explanation:

From the segment BD, I will consider the point B as the begin and D as the end of the vector, therefore [tex]\overrightarrow{BD} = \vec{v}[/tex]

Once you want a segment that is twice as long as the given segment, we may say that the magnitude of the vector is

[tex]||2\vec{v} || = \sqrt{(2x)^2 + (2y)^2} = \boxed{ \sqrt{4x^2 + 4y^2} }[/tex]

Note: I'm assuming [tex]\vec{v} \in E^2[/tex], which means the segment is in the plain.

Answer:

f(10) = 8

Step-by-step explanation:

f(x) = 4(x - 8)

Let x = 10

f(10) = 4 ( 10-8)

       = 4 ( 2)

      = 8

Here, we are provided with a polynomial in x and it's general value in variable X is also given.

[tex]f(x) = 4( x - 8)[/tex]

We need to find the value of f(10)

For this, we need to substitute the value of x with 10, because we are required to find f(10)

Given polynomial, f(x) = 4(x - 8), Putting value of x

[tex]f(10) = 4(10 - 8)[/tex]

[tex]f(10) = 4(2)[/tex]

[tex]f(10) = \boxed{ \red{8}}[/tex]

This is our required answer !!

Answer:

[tex]\boxed{\tt -311}[/tex]

Step-by-step explanation:

We are given the expression:

[tex]g^5-h^3[/tex]

and asked to solve when [tex]g=2[/tex] and [tex]h=7[/tex].

Substitute 2 in for g and 7 in for h.

[tex](2)^5-(7)^3[/tex]

Evaluate the exponents.

⇒ 2⁵= 2*2*2*2*2= 32

[tex]32-(7)^3[/tex]

⇒7³= 7*7*7=343

[tex]32-343[/tex]

Subtract 343 from 32.

[tex]-311[/tex]

The expression g⁵-h³ evaluated for g=2 and h=7 is equal to -311

Answer:

A. Brian will need 1.75 (1 3/4) cups of flour

B. Brian will need 1 1/16 cups of sugar

Step-by-step explanation:

Brian wants to make it for 3 people, so everything must be divided by 4 since 12/4=3.

7/4=1.75

4 1/4 divided by 4=1 1/16

Answer:A is 21 cups of flour and B is 12 3/4 cups of sugar

Step-by-step explanation:

A is 21 because 7x3 is 21 and B because 4 1/4x3 equals 12 and 3/4 cups

Answer:

[tex]7 {}^{0} = 1[/tex].

In any number if the power of the number is 0,then it will be 1.

Answer:

Step-by-step explanation:

Let the angles be x and y

If the two angles are complementary then their sum is 90 i.e x+y = 90

x = 90-y

If the two angles are supplementary, then their sum is 180 i.e x+y = 180

x = 180-y

If two times the complement of an angle is 23 less than the supplementary of the angle, this is written as;

2(90-y) = (180-y)-23

180-2y = 157-y

-2y+y = 157-180

-y = -23

y = 23

Hence the angle is 23°

Answer:

A) 1,492

B) 1,908

Step-by-step explanation:

A) The equation set up for this part is 1,542-50=1,492 We know that we're subtracting 50 from 1,542 because it say that the plane starts below sea level.

B) The equation set up for this part is 3,400-1,492=1,908 We know that we're subtracting the answer from part A from 3,400 because the plane will need to climb the difference in order to reach 3,400.

Answer:

36 = 2.25(x)

Number of slices = 16 slice

Step-by-step explanation:

Given:

Total amount spend = $36

Cost of each slice = $2.25 per slice

Number of slices = x

Find:

Equation

Computation:

Total amount spend = Cost of each slice × Number of slices

36 = 2.25(x)

x = 16

Number of slices = 16 slice

Answer:

b

Step-by-step explanation:

The sum of the first ten terms of the sequence is -59,048. The correct option is C.-59,048

Here is the correct question:

What is the sum of the first ten terms of the sequence 4, -12, 36, -108...

From the question,

The given sequence is 4,-12, 36, -108...

This is a geometric progression since it has a common ratio.

The common ratio, r = -3

Recall that,

Given a geometric progression, the common ratio, r is given as

[tex]r = \frac{T_{2} }{T_{1}} = \frac{T_{3} }{T_{2}} =\frac{T_{4} }{T_{3}} = ...[/tex]

From the given sequence,

[tex]T_{1} = 4[/tex]

[tex]T_{2} = -12[/tex]

[tex]T_{3} = 36[/tex]

[tex]T_{4} = -108[/tex]

∴ [tex]r = \frac{-12 }{4} = \frac{36}{-12} =\frac{-108} {36} = -3[/tex]

Therefore, the sequence is a geometric progression with a common ratio of 3

Now, to determine the sum of the first ten terms of the sequence,

From the formula

[tex]S_{n} = \frac{a(1-r^{n}) }{1-r}[/tex]

Where [tex]S_{n}[/tex] is the sum of n terms

[tex]a[/tex] is the first term

[tex]r[/tex] is the common ratio

and [tex]n[/tex] is the number of terms in the series

From the question

[tex]a = 4[/tex]

[tex]r = -3[/tex]

and [tex]n = 10[/tex] (Since, we are to determine the sum of the first 10 terms)

Now, put the parameters into the formula

[tex]S_{n} = \frac{a(1-r^{n}) }{1-r}[/tex]

We get

[tex]S_{10} = \frac{4(1-(-3)^{10}) }{1-(-3)}[/tex]

[tex]S_{10} = \frac{4(1-59049) }{1+3}[/tex]

[tex]S_{10} = \frac{4(-59048) }{4}[/tex]

[tex]S_{10} = \frac{-236192 }{4}[/tex]

[tex]S_{10} = -59048[/tex]

Hence, the sum of the first ten terms of the sequence is -59,048. The correct option is C.-59,048

Answer:

(s+2)^3

Step-by-step explanation:

I think this is referring to a square as a box, so the length of a jewelry box would be s. We learn that a shipping box is 2 inches longer, so s+2 = the length of the shipping box.

Volume = Length*Width*Height, but if square, all dimensions are the same, so s+2 to the power of 3 would be your answer.
