Answer: y=5, x=4

Step-by-step explanation:

3y= 15 divide both sides by 3

Y= 5

4x = x+12 subtract x from both sides.

3x = 12 divide both sides by 3

X= 4

The equation for the future value of a deposit earning compound interest is equation <img src="https://tex.z-dn.net/?f=V%28t%29%
scoundrel [369]

Answer:

Given that:

The equation for the future value of a deposit earning compound interest is equation:

V(t) = P(1+\frac{r}{n})^{nt}              .....[1]

where,

P = the initial deposit

t = years invested

r = rate at which interest is compounded annually

.

n = number of times the interest is compounded per year

As per the statement:

After 10 years, a $2,000-dollar investment compounded annually has grown to $3600.

⇒P = $2000 and V(t) = $3600

Substitute in [1] we have;

3600 = 2000(1+\frac{r}{1})^{10 \cdot 1}

Divide both sides by 2000 we have;

1.8 = (1+r)^{10}

Taking log base 10 both sides we have;

\log_{10} 1.8 =\log_{10} (1+r)^{10}

⇒0.255272505 = 10 \log_{10} 1+r

Divide both sides by 10 we have;

0.0255272505 =\log_{10} 1+r

⇒10^{0.0255272505} = 1+r

Simplify":

1.06= 1+r

Subtract 1 from both sides we have;

0.06=r

or

r = 0.06 = 6%

Therefore, 6%  is the  interest rate to the nearest whole-number percent

How many grams of water would require 4000 joules of heat to raise its temperature from
serious [3.7K]

Answer: 27.33 g water

Step-by-step explanation:

For this problem, we will need to use the equation for heat: q=mCΔT. Since we are given heat, change in temperature, and specific heat, all we have to do is plug them in to find grams.

4000J=m(4.181J/g°C)(100-65°C)              [find change in temperature]

4000J=m(4.181J/g°C)(35°C)    [divide both sides by specific heat and change in temperature]

m=27.33 g
