Answer:

y = 48° is the answer.

Step-by-step explanation:

In the figure attached, length of small arc = 66°

This small arc makes an angle at the center of the circle = 66°

By definition, angle formed by the arc at the center is double of the measure of the angle inscribed by the small arc at the point on a circle.

Therefore, m (arc) = 66° = 2.(x)

x = [tex]\frac{66}{2}=33[/tex]

Similarly,  y = [tex]\frac{96}{2}=48[/tex]

y = 48° will be the answer.

Step-by-step explanation:

to find the first, fourth and tenth terms, substitute n = 1, 4, 10 into the rule

A(1) = - 3 + (1 - 1)(- 2.2) = - 3 + (0 × - 2.2) = - 3 + 0 = - 3

A(4) = - 3 + (4 - 1)(- 2.2) = - 3 + (3 × - 2.2) = - 3 - 6.6 = - 9.6

A(10) = - 3 + (10 - 1)(- 2.2) = - 3 + (9 × - 2.2) = - 3 - 19.8 = - 22.8

the required terms are - 3, - 9.6, - 22.8

Answer:

∠2 = 115.5°

Step-by-step explanation:

128.5° is an exterior angle of the triangle

The exterior angle equals the sum of the 2 opposite interior angles, hence

∠2 + 13 = 128.5 ( subtract 13 from both sides )

∠2 = 115.5°

A differential equation is an equation that contains one or more functions with its derivatives. The value of h'(3) iss 14.

A differential equation is an equation that contains one or more functions with its derivatives.

Given

h(x) = g(f(x))

Let us differentiate with respect to x by using chain rule we get

h'(x) = g'(f(x))f'(x)

plug the value x =3 in the above equation

h'(3) = g'(f(3))f'(3)

The value of f(3)=4, f'(3)=7 by table given

Plugging in values we get

h'(3) = g'(4)×7

We have g'(4)=2

so h'(3) = 2×7

h'(3) = 14

Hence the value of h'(3) is 14.

Answer:

8a + 2b + c

Step-by-step explanation:

For subtracting polynomials we just need to operate subtracting the terms with same unknown. In our case we sum/subtract the terms that include a between them, the terms that have b between them and the therms with c between them. So we have:

(13a−4b+8c) - (5a−6b+7c) =?

13a−4b+8c - 5a+6b-7c = ?

Lets operate putting together terms with same unknown:

(13a - 5a) + (-4b +6b) + (8c-7c) =

8a + 2b + c

So, if we subtract 5a−6b+7c from 13a−4b+8c we get 8a + 2b + c

I hope it is clear!

Answer:

x < the quantity negative 3 times b plus 5 all over negative 2

Step-by-step explanation:

−2x + 3b > 5

Subtract 3b from both side.

-2x +3b -3b > 5-3b

-2x > 5-3b

Divide by -2 on both sides, remember to flip the inequality since we are dividing by a negative

-2x/-2 < 5/-2 - 3b/-2

x < (5-3b)/-2

x< (-3b+5)/-2

Answer

By similar methods the next 2 items will be 32 and 64.

Note

The next three numbers in the given pattern (1,2,4,8) are 16, 32, and 64, obtained by doubling the last known number in the series for each subsequent term.

This question is related to a mathematical pattern in which each number is being doubled to get the next one. The series given is 1, 2, 4, 8. Here, you can notice that each successive number is two times the prior number. So, to find the next three numbers, you'd multiply the last given number by 2.

When you multiply 8 (the last number in the given series) by 2, you get 16. That's your first number. Continuing this pattern:

So, the next three numbers in this pattern would be 16, 32, and 64.

Answer:

k > -26

Step-by-step explanation:

To isolate the k, you subtract 6 from both sides to get k < -26.

The correct answer is k > -26

Explanation:

To solve our equation first we need to set out our equation, k + 6 > -20. Next, we have to subtract 6 from both sides of the equation, k + 6 - 6 > -20 - 6 =      k > -26. Finally, we have our answer of k > -26.

Step-by-step explanation:

P(1+r/n)^nt

10000 (1 + (.05/12))^ (12*8)

Answer:

she will have $14,906 in December of year 2018

Step-by-step explanation:

To find the amount of money she will have in December of the year 2018, we will simply use the formula;

Compound Interest: A = P ( 1 + r/n )^nt

where p = principal

           R = rate

           n = the number of times the interest is compounded per unit time

            T = time

             A= Accrued amount

From the question

Principal (p) = $10,000

Rate (r) = 5% = 0.05

Time(t) = 2018-2010 = 8 years

n = 12

We can now proceed to insert the values into our formula;

Compound Interest: A = P ( 1 + r/n )^nt

                                      = $10 000 ( 1 + 0.05/12) ^12×8

                                         =$10,000(1 + 0.00416667)^96

                                          = $10 000(1.00416667)^96

                                            =$10 000(1.4905859)

                                            =$14,905.895

                                             ≈$14,906 to the nearest whole number.

Therefore she will have $14,906 in December of year 2018

3 is the greatest number of book shelves Andy can use.

Step-by-step explanation:

You can solve this by finding the greatest common factor of 9 and 6, which turned out to be 3.

9/3 =3 (math books per shelf)

Every shelf there are 2 reading books and 3 math books.

If someone deposits Rs 40000 in a bank at the rate of 5% p.a. after paying 5% tax, the amount he will get after 4 years is Rs 47600.

How the amount is determined:

Principal amount (P) = Rs. 40000

Rate of interest (R) = 5% per annum

Time period (T) = 4 years

We can calculate the simple interest using the formula:

[tex]\text{Simple Interest} = \frac{{P \cdot R \cdot T}}{{100}}[/tex]

Plugging in the values:

[tex]\text{SI} = \frac{{40000 \times 5 \times 4}}{{100}}[/tex]

= Rs 8000

Total Income after 4 years = Principal + Interest

Total Income = 40000 + 8000 = Rs 48000

Income Tax on Interest: The income earner needs to pay 5% income tax on the interest earned

Tax to Pay = 5% of Rs 8000 = Rs 400

Final Amount Received after Tax = Total Income - Tax to Pay

= 48000 - 400

= Rs 47600

Complete Question:

If someone deposits Rs 40000 in a bank at the rate of 5% p.a.  If he has to pay 5% of interest as income tax, how much will he get after 4 years?
