find the length of EF in this Pythagorean theorem problem and show work please and thanks you​

Answers

Answer:

I'm not sure if you can solve this with Pythagorean Theorem because as far as I know, you need sides not angle+side combination. Despite this, let's solve this one using sine law, cosine law or even tangent.

Step-by-step explanation:

[tex] \tan(61) = \frac{length \: of \: df}{24} \\ length \: of \: df = 24 \tan(61) \\ = 43.2971 \\ \\ \cos(19) = \frac{length \: of \: df}{length \: of \: ef} \\ length \: of \: ef \: = \frac{43.2971}{ \cos(19) } \\ = 45.7919[/tex]

Multiply k by 5, and then add 3 to the product. Could you plz help me

Answers

Answer:

''Multiply k by 5, and then add 3 to the product'' means:

5k + 3

Step-by-step explanation:

Let the number be: k

When we multiply k by 5, we get the product of k and 5.

In other words,

Multiply k by 5:  5k

Add 3 to the product means we need to add 3 to 5k.

In other words,

Add 3 to the product 5k: 5k + 3

Therefore,

''Multiply k by 5, and then add 3 to the product'' means:

5k + 3

if you square (x-4), open pharenthesis -(x-4) and then combine like terms

x^2 +16-8x -x+4-6 =0

x^2 -9x +14 =0

Answers

Answer:

x = 7

y = 3

Step-by-step explanation:

[tex]\triangle ABC[/tex] is an equilateral triangle so that means all sides are equal

which means

[tex]AB= BC=AC\\\\7=x[/tex]

now in [tex]\triangle ACD[/tex]  is an isosceles triangle so that means opposite sides to the angles that have the same measure are equal

which means

[tex]AC=CD\\\\AC = y+4[/tex]

now remember that AC is a side of the equilateral [tex]\triangle ABC[/tex] so AC = 7

solving for y

[tex]7=y+4\\\\7-4 = y\\\\3=y[/tex]

so

[tex]x = 7\\\\y = 3[/tex]

Step-by-step explanation:

Consider a student loan of ​$15,000 at a fixed APR of ​6% for 25 years. a. Calculate the monthly payment. b. Determine the total amount paid over the term of the loan. c. Of the total amount​ paid, what percentage is paid toward the principal and what percentage is paid for interest.

Answers

9514 1404 393

Answer:

  a) $96.65

  b) $28,995

  c) 51.7% to principal; 48.3% to interest

Step-by-step explanation:

a) The monthly payment is given by the amortization formula:

  A = P(r/12)/(1 -(1 +r/12)^(-12t))

where P is the loan amount, r is the annual rate, and t is the number of years

Filling in the given values, we find ...

  A = $15,000(0.06/12)/(1 - (1 +0.06/12)^(-12(25))) ≈ $96.65

The monthly payment is $96.65.

__

b) The 300 payments total ...

  $96.65 × 300 = $28,995

The total amount paid is $28,995.

__

c) The percentage paid toward the principal is ...

  $15,000/$28,995 × 100% ≈ 51.7%

The remainder is paid toward interest: 100% -51.7% = 48.3%

51.7% is paid toward principal, 48.3% is paid for interest.

I would advise using organic calculator, but I’ll go with the algebraic way!

First we need to substitute each number into the equation. So let’s go with A:

5 is x and 8 is y, therefore:
8=4(5)+3
8=20+3
8=23 => THIS IS INCORRECT!! So we move on to the B!

3 is x and 15 is y
15=4(3)+3
15=12+3
15=15! => THIS IS CORRECT ANSWER!

Asanji left the science museum and drove toward the lake at an average speed of 45 km/h. Sometime later Huong left driving in the same direction but at an average speed of 75 km/h. After driving for three hours Huong caught up with Asanji. How long did Asanji drive before Huong caught up?

Answers

Answer:

Asanji drove for [tex]5[/tex] hours before Huong caught up

Step-by-step explanation:

Let the time for which Asanji drove alone is "X" hours

Asanji and Huong met after three hours of driving of Huong.

Total time for which Asanji drove [tex]= X+3[/tex] hours

Thus, distance travelled by Asanji in [tex]X+3[/tex] hours is equal to distance travelled by Huong in [tex]3[/tex] hours

[tex]45 ( X+3) = 75 (3)\\[/tex]

On solving the above equation, we get -

[tex]45 X + (45 *3) = 75 *3\\45 X = (75-45)*3\\45 X = 30 *3 \\X = \frac{30 *3}{45} \\X = 2[/tex]

Asanji drove for [tex]3 + 2 = 5[/tex] hours before Huong caught up

Express -5x(x+6) = 4(x-3)-10 in the form ax^2+bx+c=0 (quadratic formula)

Answer:

Step-by-step explanation:

-5x ( x + 6 ) = 4 ( x - 3 ) - 10

Distribute

[tex]-5x^{2} - 30x = 4x - 12 - 10[/tex]

Simplify,

[tex]-5x^{2} -30x = 4x -22[/tex]

Inverse operations;

[tex]-5x^{2} - 30x = 4x - 22\\ +30x +30x\\\\-5x^{2} = 34x - 22\\+5x^{2} +5x^{2}\\\\5x^{2} + 34x - 22[/tex]

Answer:

5x^2 + 34x - 22 = 0

Step-by-step explanation:

-5x(x+6) = 4(x-3)-10

-5x^2 - 30x = 4x - 12- 10

-5x^2 - 30x - 4x + 22 = 0

-5x^2 - 34x + 22 = 0
