Answer 1

Answer:

the answer is c) 2n+8

Step-by-step explanation:

This is because the expession applies to every figure when calculating the amount of sides

figure 1- 2(1)+8 = 2+8 = 10

figure 2- 2(2)+8 = 4+8 = 12

figure 3- 2(3)+8 = 6+8 = 14

Yes, the expression is true for every figure, proving that it can solve for the perimeter

hope this helps :)

HOW IS THE ANSWER 98 PLS HELP ASAP

Answers

Answer:

The answer is 98, here's how:

Step-by-step explanation:

Lets solve the numerator of the fraction first:

-[5.8 - 3(3.2)] =

-[5.8 - 9.6] =

-[-3.8] = 3.8               (Watch out for the double negative)

Now lets solve for the denominator :

(-0.2)² =

(-0.2)(-0.2) = 0.04

Lets simplify the fraction:

[tex]\frac{3.8}{0.04} = 95\\[/tex]

Let's add the 3 to 95:

95 + 3 = 98

-Chetan K

Step-by-step explanation:

[tex] \frac{ -[5.8 - 3(3.2)] }{{( - 0.2)}^{2} } + 3[/tex]

[tex]\frac{ -[5.8 -9.6] }{0.04 } + 3[/tex]

[tex]\frac{ -( - 3.8)}{0.04} + 3[/tex]

[tex]\frac{3.8}{0.04} + 3[/tex]

[tex] = 95 + 3[/tex]

If p(x)=2x2-1, find p(-3)

Answers

Given the function, p(x) = 2x^2 - 1, to evaluate p(-3), you could simply substitute -3 as the input of the function.

p(-3) = 2(-3)^2 - 1

p(-3) = 2(9) - 1

p(-3) = 18 - 1

p(-3) = 17

Therefore, p(-3) = 17.

I'm trying to find the explicit form of an equation after performing an integration. I'm a bit rusty.

ln|y| = C - cos(x)

C is an arbitrary constant.

Is it:

y = e^(c-cos(x))

or because it's an arbitrary constant, can it be written:

y = C - e^(cos(x))

Thanks.

Answers

No, it should be written as

[tex]y = Ce^{-\cos x}[/tex]

Provided that y ≠ 0, both solutions

[tex]y = e^{C-\cos(x)}[/tex]

and

[tex]y = Ce^{-\cos(x)}[/tex]

are correct. The other solution you provided,

[tex]y = C - e^{\cos(x)}[/tex]

is not.

The only difference between the "valid" solutions lies in the particular value of the arbitrary constant C.

Suppose y(0) = Y ≠ 0 is given as an initial condition. Then in the first solution,

[tex]Y = e^{C - \cos(0)} \implies \ln|Y| = C - 1 \implies C = \ln|Y| + 1[/tex]

In the second solution,

[tex]Y = C e^{-\cos(0)} \implies Y = Ce^{-1} \implies C = eY[/tex]

But both solutions are the same, since

[tex]y = e^{\ln|Y| + 1 - \cos(x)} = e^{\ln|Y|} e^1 e^{-\cos(x)} = eY e^{-\cos(x)}[/tex]

Step-by-step explanation:

Points A and B are 100m apart on a coastline.
B is directly east of A.
A lighthouse is out at sea.
The bearing of the lighthouse is
164 degrees from A and
217 degrees from B
The angle of elevation of the top of the lighthouse from A is 27 degrees.
Find the distance of the lighthouse from A.
Find the height of the lighthouse.

Answers

Points A, B and the lighthouse are related by angles of elevation.

The distance of the lighthouse from A is 97.4 mThe height of the lighthouse is 79.9 m

From the complete question (see attachment), we have:

[tex]\mathbf{\angle A = 164 - 90}[/tex]

[tex]\mathbf{\angle A = 74}[/tex]

[tex]\mathbf{\angle B = 270 - 218}[/tex]

[tex]\mathbf{\angle B = 52}[/tex]

[tex]\mathbf{\angle L = 180 - 74 - 52}[/tex]

[tex]\mathbf{\angle L = 54}[/tex]

(a) The distance between the lighthouse and A

This is calculated using the following sine ratio

[tex]\mathbf{\frac{a}{sin A} = \frac{b}{sin B} = \frac{c}{sin C}}[/tex]

So, we have:

[tex]\mathbf{\frac{AL}{sin B} = \frac{100}{sin L}}[/tex]

This gives

[tex]\mathbf{\frac{AL}{sin 52} = \frac{100}{sin 54}}[/tex]

Make AL the subject

[tex]\mathbf{AL = \frac{100}{sin 54} \times sin 52}[/tex]

[tex]\mathbf{AL = 97.4}[/tex]

The distance of the lighthouse from A is 97.4 m

(b) The height of the lighthouse

Considering triangle AHL, we have:

[tex]\mathbf{\angle H = 90 + 27 = 117}[/tex]

[tex]\mathbf{\angle A = 74 - 27 = 47}[/tex]

[tex]\mathbf{AL = 97.4}[/tex]

The height is then calculated using the following sine ratio

[tex]\mathbf{\frac{a}{sin A} = \frac{b}{sin B} = \frac{c}{sin C}}[/tex]

So, we have:

[tex]\mathbf{\frac{AL}{sin H} = \frac{HL}{sin A}}[/tex]

Make HL the subject

[tex]\mathbf{HL = \frac{AL \times sin A}{sin H}}[/tex]

This gives

[tex]\mathbf{HL = \frac{97.4 \times sin 47}{sin 117}}[/tex]

[tex]\mathbf{HL = 79.9}}[/tex]

Hence, the height of the lighthouse is 79.9 m

Which is greater?

1/4 vs. 3/5

Answer: 3/5 So...

-2 3/5 would be the least.

Then there would be -2 1/4

Then, it would be 1.2 because 1.2 is smaller than 7/4.

Therefore, this pattern would be the correct answer...

$5400 at 3.6% compounded continuously for 5 years.

Answers

Answer:

A = $6,464.97

Step-by-step explanation:

Given the principal amount of $5,400, and an interest rate of 3.6% compounded continuously for t = 5 years:

Substitute the given values into the Continuous Compounding Formula:

[tex]A = Pe^{r*t}[/tex]

where:

P = principal = $5,400

e ≈ 2.7183 (irrational number)

r = interest rate = 3.6% or 0.036

t = time in years = 5

[tex]A = Pe^{r*t}[/tex]

[tex]A = 5400e^{(0.036*5)}[/tex]

[tex]A = 5400e^{0.18}[/tex]

A = $6,464.97

Therefore, the amount after compounding continuously for 5 years is $6,464.97.

Answers

Answer: $225

Step-by-step explanation:

Each Notebook costs 45 dollars, this can be found by taking the cost of 2 (90$) and dividing it by 2

Now just take the cost per notebook (45) and multiply it by the amount wanted (5) and your total should come out to $225

- Gage Millar, Algebra 2 Tutor

Answer:

$225 = 5 note books.

45 = 1 note book

Step-by-step explanation:

90/2 = $45 EACH

Unitary method means find 1 part first.

Therefore,

1 part = 45

45 x 5 = 225

$225 = 5 note books.
