$3.66

Step-by-step explanation:

5.00-2.00 = 3.00

0.95-0.29 = 0.66

3.00 + 0.66 = $3.66 which is the answer

Ok,so:

We don’t need the $ sign now.

So.

1. 5.95 -2.29 which is 3.66!

5 - 2 is 3, and 0.95 - 0.29 is 0.66.

So now add :3 + 0.66 is 3.66

So $3.66!

Given that Cos(A) = .6 and csc(A) is -1.25, what is tan (a)

Answers

Answer:  -4/3

============================================================

Explanation:

cos(A) = 0.6 = 6/10 = 3/5

Recall that csc is the reciprocal of sine.

If csc(A) = -1.25, then sin(A) = 1/csc(A) = 1/(-1.25) = -0.8 = -8/10 = -4/5

Then we would have

tan(A) = sin(A)/cos(A)

tan(A) = sin(A) ÷ cos(A)

tan(A) = (-4/5) ÷ (3/5)

tan(A) = (-4/5) * (5/3)

tan(A) = -4/3

Answer:

-4/3

The measure of angle CFD is The measure of angle CDF is The measure of angle AFB is The measure of angle BFD is The measure of angle ABC is

Answers

Answer:

∠CDF = 23° ,  ∠CFD = 115° , ∠AFB = 115° , ∠BFD = 65° , ∠ABC = 42°

Step-by-step explanation:

m∠CDF = 180 - m∠CDE

m∠CDF = 180 - 157

m∠CDF = 23°

m∠CFD = 180 - ( m∠DCF + m∠CDF )

m∠CFD = 180 - ( 42 + 23 )

m∠CFD = 115°

m∠AFB = m∠CFD (Vertically opposite angles)

m∠AFB = 115°

m∠BFD = 180 - m∠CFD

m∠BFD = 180 - 115

m∠BFD = 65°

∠ABC

Solution 1:

m∠ABC = m∠DCF (Alternate angles)

m∠ABC = 42°

Solution 2:

In ΔAFB

m∠FAB = m∠CDF (Alternate angles)

m∠FAB = 23°

m∠ABC = 180 - ( m∠AFB + m∠FAB )

m∠ABC = 180 - ( 115 + 23 )

m∠ABC = 42°

In year, 2004, I put $20.00 into an account to save. This account annual interest fee is 0.002%. However, every 10th year the interest rate get doubled and is now 0.004%. After, the 10th year it goes back to the original interest rate of 0.002% annually. If I check the amount I know have in total included my principal of $20.00, in the year of 2021. What would the total amount be of putting it there

Answers

9514 1404 393

Answer:

  $20.01

Step-by-step explanation:

In 2004–2012, the interest rate is 0.002%. In 2013, it is 0.004%. In 2014–2021, the interest rate is 0.002%. That is, in the 18 years between 2004 and 2021 (inclusive), the interest rate is 0.002% for 17 of them. The effective account multiplier is ...

  (1.00002^17)(1.00004^1) = 1.00038006801

Then the account balance is ...

  $20 × 1.00038006801 ≈ $20.01

_____

Additional comment

The annual interest earned on $20.00 is $0.0004. If the account balance is rounded to the nearest cent annually, at the end of the 18 years, the balance will still be $20.00. Not enough interest is earned in one year to increase the balance above $20. At the end of the 18 years, the amount of interest earned is 0.76¢ (a fraction of a penny) only if there is no rounding in intervening years.

Okay, so, start by rearranging the problem (because it’s multiplication, you can do that), you get

(sin^2(x)-cos^2(x))*cos(x)*sec(x) + cos^2(x)

cos and sec are inverses, so they cancel each other out leaving you with

The cos^2(x) cancel each other out leaving you with

<1 and <2 are complementary. Solve for the measure of <1.

<1 = 12x + 4
<2 = 9x + 2

A. 52
B. 4
C. 38
D. 8.3

Answers

Answer:

A) 52

Step-by-step explanation:

If < 1 and < 2 are complementary angles, then it means that the sum of their measures add up to 90°.

< 1 + < 2 = 90°

12x + 4 + 9x + 2 = 90°

21x + 6 = 90°

21x + 6 - 6 = 90° - 6

21x = 84°

21x/21 = 84°/21

x = 4

Substitute the value of x = 4 into < 1 and < 2:

m < 1: 12x + 4 = 12(4) + 4 = 52°

m < 2: 9x + 2 = 9(4) + 2 = 38°

Therefore, the correct answer is A) m < 1 = 52°.

Olivia buys 0.5 pounds of ricotta cheese and 0.25 pounds of parmesan cheese. The parmesan cheese costs $5 more than the ricotta cheese. She pays a total of $9.50. What is the cost for a pound of parmesan? What is the cost for a pound of ricotta? NEED ANSWER QUICKLY.

Answers

Answer:

$16

Step-by-step explanation:

let x = cost of ricotta cheese

let x + 5 = cost of parmesan cheese

.5x + .25(x+5) = $9.5

solve this and we get x =11 (cost per pound for ricotta)

now we plug that value back into x + 5 to find the cause of the cost of parmesan cheese

11 +5 = 16y = 16

The cost of ricotta cheese will be $11. And the cost of parmesan cheese will be $16.

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

Olivia buys 0.5 pounds of ricotta cheese and 0.25 pounds of parmesan cheese. The parmesan cheese costs $5 more than the ricotta cheese. She pays a total of $9.50.

Let 'x' be the cost of ricotta cheese. Then the cost of parmesan cheese will be (x + 5). Then the equation is given as,

0.5x + 0.25 · (x + 5) = $9.5

Simplify the equation, then we have

0.5x + 0.25 · (x + 5) = $9.5

0.5x + 0.25x + 1.25 = $9.5

0.75x = 8.25

x = $11

Then the cost of parmesan cheese is given as,

x + 5 = $11 + 5

x + 5 = $16

The cost of ricotta cheese will be $11. And the cost of parmesan cheese will be $16.

Answer:

  C.  1/(4a)

Step-by-step explanation:

We assume you're comparing the vertex form ...

  y = a(x -h)^2 +k

to the form used to write the equation in terms of the focal distance p.

  y = 1/(4p)(x -h)^2 +k

That comparison tells you ...

  a = 1/(4p)

  p = 1/(4a) . . . . . . multiply by p/a; matches choice C

Additional comment

When using plain text to write a rational expression, parentheses are needed around any denominator that has is more than a single constant or variable. The order of operations requires 1/4a to be interpreted as (1/4)a. The value of p is 1/(4a).

When rational expressions are typeset, the fraction bar serves as a grouping symbol identifying the entire denominator:
