somebody pls help me for question a. i will mark u as brainliest. promise.

a) simplify (cosec^2 a-1) (sec^2 a sin^2 a)

Answers

Answer 1

Step-by-step explanation:

[tex](\csc^2 a - 1)(\sec^2 a\sin^2 a)[/tex]

[tex]\:\:\:\:\:\:=\left(\dfrac{1 - \sin^2 a}{\sin^2 a}\right)\left(\dfrac{\sin^2 a}{\cos^2a}\right)[/tex]

[tex]\:\:\:\:\:\:= \dfrac{1 - \sin^2 a}{\cos^2 a}[/tex]

Using the identity [tex]\sin^2 a + \cos^2 a = 1[/tex]

[tex](\csc^2 a - 1)(\sec^2 a\sin^2 a) = \dfrac{\cos^2 a}{\cos^2 a} = 1[/tex]

D! 33.85 is 15 less than 34 and 16.29 is 29 more than 16

Answer:

D. Subtract 15 cents and add 29 cents

Step-by-step explanation:

He should subtract 15 cents and add 29 cents. This is because at 33.85 we estimated to 34 dollars which was 15 cents higher, so we must subtract by 15 to get to the exact cost. We also need to add 29 cents since we rounded down from 16.29 to 16.

A representative from the bank speaks with you about opening a savings product. You would be guaranteed at least a 3.5% return for the next 10 years when you agree to add $25.00 each month for the entire time. Given this information and that you meet the minimum monthly contribution requirement, what would be your total accumulated value at the end of the 10 years?

Answers

Answer:

a 3.5 % return is .035/12 - .002917 / mo

10 years is 120 mos.

This is basically an annuity payment - after 10  years 1$, deposited monthly, would be worth (similar to house mortgage, etc.)

N = (1 - (1 + i)^-120) / i  = 241.73

Total amount = 25 * 241.73 = 6043

Note 120 payments at $25 = 3000

A number is doubled and then increased by seven. The result is fifty-one. What is the original number?

Answers

Answer: I believe it's 22

Step-by-step explanation:

51 - 7 = 44

If the result is 55 and was increased by 7, you'll subtract 7 from 55 and you'll get 44.

44/2 = 22

To find the number that is doubled and makes up 44, you'll divide 2 from 44 and you'll get 22


A store owner sold 4 paint brushes for $12.00 and 8 pens for $3 20. What is the difference between the unit price of a paint brush and the unit price of a pen? 50 POINTS FOR THIS

Answers

Answer:

$2.6

Step-by-step explanation:

12/4=3 that means each paintbrush cost $3

3.20/8=0.4 that means each pen cost $0.40

3-0.4=2.6

$12/4=3 so each paint brush costs $3. $3.20/8=.40 so each pen costs $0.40. The difference between the unit price of a paint brush and unit price of pen gives you the equation 3-.40= $2.6

identify the solutions of the inequality 5 ≤ s − 6

Answers

Answer:

s≥11

Step-by-step explanation:

5 ≤ s -6

=5 + 6 ≤ s

=11 ≤ s or s≥11

The solution to given inequality  5 ≤ s − 6 for s will be s ≥ 11.

What is inequality?

A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.

Inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.

Given the inequality,

5 ≤ s − 6

Subtracting by 5 on both sides,

5 - 5 ≤ s - 6 - 5

0 ≤ s - 11

Adding 11 on both sides

0 + 11 ≤ s - 11 + 11

11 ≤ s or s ≥ 11

Hence "The solution to given inequality  5 ≤ s − 6 for s will be s ≥ 11".

Let's solve for w :

[tex] \dfrac{2w + 4}{2} = 6 - w[/tex]

[tex]2w + 4 = 2( 6- w)[/tex]

[tex]2w + 4 = 12 - 2w[/tex]

[tex]2 w+ 2w = 12 - 4[/tex]

[tex]4w = 8[/tex]

[tex]w = 8 \div 4[/tex]

[tex]w = 2[/tex]

hence , value of w = 2 ~

Answer:

Choice d. w = 2 is correct

Step-by-step explanation:

[tex] \\ \frac{2w + 4}{2} = 6 - w[/tex]

[tex] \\ \mapsto2w + 4 = 2(6 - w)[/tex]

[tex] \\ \mapsto2w + 4 = 12 - 2w[/tex]

Step-by-step explanation:

The amount at the end of March can be found two ways:

  add up the deposits for Jan, Feb, Mar:

     1200.32 +985.43 +1200.65 = 3386.40

  subtract Apr and May from the May total:

     6374.72 -1000.98 -1987.34 = 3386.40

The total amount of money that he had deposited into his account at the end of March is $3386.40.

Deon plans to ride a 15 mile bicycle trail. If his average speed is 20mi/h, which equation can he use to find the time t, in hours, for the ride?

Answers

Answer

15=20t

Step-by-step explanation:

Answer:

t = 15 / 20

Step-by-step explanation:

Given:

Distance traveled by Deon to ride a bicycle trail = 15 mile

Average speed of Deon to ride a bicycle trail = 20 mi/hour

Step-by-Step:

Let 'T' be the time taken to ride the bicycle trail.

We will use distance speed formula to write the equation to find the time 'T' in hours, for the ride.

[tex]Distance=\frac{Speed}{Time}[/tex]

Distance = 15 miles

Speed = 20 miles / hour

Time = 15 / 20

Assuming time is t, the formula would be:

t = 15 / 20

"t = 15 mi/ 20 mi/hr " will help Deon calculate the time he will take.

Therefore, t = 15 / 20
