In ABC, if the lengths of sides a and c are 8 centimeters and 16 centimeters, respectively, and the measure of C is 35 degrees,

Answer:

∠ A ≈ 16.67°

Step-by-step explanation:

Using the Sine rule in Δ ABC

$\frac{a}{sinA}$ = $\frac{c}{sinC}$ , substitute values

$\frac{8}{sinA}$ = $\frac{16}{sin35}$ ( cross- multiply )

16 sinA = 8 sin35° ( divide both sides by 16 )

sin A = $\frac{8sin35}{16}$ , thus

∠ A = $sin^{-1}$ ( $\frac{8sin35}{16}$ ) ≈ 16.67° ( to 2 dec. places )

For the functions u(t) = 8t – 14 and s(t) = t2– 16, what is s (u (3))?

Answer:

Step-by-step explanation:

u(3) = 8(3) - 14 = 24 - 14 = 10

s(10) = 10^2 - 16 = 100 - 16 = 84

Becky Anderson must pay a lump sum of $6000 in 5 yr. If only $5000 is available to deposit right now, what annual interest rate

Hello!

Out equation is: $A=P(1+\frac{r}{n} )^t^n$

A= 6000

P=5000

N=1

T=5

R= What we are trying to find

This means we will have $6000=5000(1+r)^5$

Divide both sides by 5000:

$\frac{6000}{5000} = (1+r)^5$

Move the power to the other side by rooting both sides:

$\frac{6000}{5000} ^1^/^5 = 1+r$

Subtract 1 from both sides:

$\frac{6000}{5000} ^1^/^5 -1 = r$

Now we just need to calculate: R = 0.03713728...

I don't know how many decimal places you can have, but I will round to 2. This will give you an Interest Rate of 3.71%.

I hope this helps! :)

Answer:

Thus, option A is correct.

Explanation:

match the proportions

$240,000 → 60%

x → 100%

set up a equation:

$\sf \dfrac{60}{100} = \dfrac{240,000}{x}$

$\sf x = \$400,000$
