Answer:

{a, b, c, d, e, f} 1st Option

Step-by-step explanation:

"U" means unite them together so you would put all them (numbers/letters) together, if a and b sets have the same letters, only mention them once in order.

Find m<YQR pls need grade gud.

DaniilM [7]

Answer:

21°

Step-by-step explanation:

We can prove these two triangles congruent by the HL (Hypotenuse-Leg) theorem. Then, we know that m<YQR is congruent to m<PQY. We can then use their given values to form an equation.

5x+6=16x-27

Continue to solve . . .

33 = 11x

x=3

Therefore, we can plug this value of 3 into the expression for the value of m<YQR, and you will get

(16 x 3) - 27, which is equal to 21°.

5x + 15 = 45

Subtract 15 from both sides

5x = 30

Divide by 5 on both sides

x = 6

Find the amount to which $2,500 will grow if interest of 6.75% is compounded quarterly for 10

andreev551 [17]

Answer:

Part a

For this case n = 4. If we use the future value formula we got:

$A= 2500 (1+ \frac{0.0675}{4})^{4*10}= 4882.506$

Part b

For this case n = 365. If we use the future value formula we got:

$A= 2500 (1+ \frac{0.0675}{365})^{365*10}= 4909.776$

Step-by-step explanation:

We can use the future vaue formula for compound interest given by:

$A= P(1+ \frac{r}{n})^{nt}$

Where P represent the present value, r=0.0675 , n is the number of times that the interest is compounded in a year and t the number of years.

Part a

For this case n = 4. If we use the future value formula we got:

$A= 2500 (1+ \frac{0.0675}{4})^{4*10}= 4882.506$

Part b

For this case n = 365. If we use the future value formula we got:

$A= 2500 (1+ \frac{0.0675}{365})^{365*10}= 4909.776$
