A 6-ft ladder is placed against a wall with its base 2 ft from the wall. How high above the ground is the top of the ladder

1 answer:

4 0

Use pythagorean theorem - a^2+ b^2 = c^2
a = 2ft, b = ?, c = 6ft
2 x 2 + b^2 = 6 x 6
4 + b^2 = 36
b^2 = 36 - 4 = 32
b = square root of 32
= 5.66ft

If \$z_1=3+2i\$ and \$z_2=4+3i\$ and are complex numbers, find \$z_1z_2\$

Dmitry_Shevchenko [17]

$z_1z_2=(3+2i)(4+3i)=3\cdot4+2i\cdot4+3\cdot3i+2i\cdot3i$

$z_1z_2=12+8i+9i+6i^2$

$i^2=-1$ , so

$z_1z_2=12+8i+9i-6=\boxed{6+17i}$

a person invest $1,700 in an account that earns 3.97% annual interest. find when the value of the investment reaches $3,200

olga_2 [115]

Answer:

16 1/4 years

Step-by-step explanation:

Assuming interest is compounded annually, the account balance (A) after t years will be ...

A = P(1 +r)^t

3200 = 1700·1.0397^t

log(3200) = log(1700) +t·log(1.0397)

t = (log(3200) -log(1700))/log(1.0397) ≈ 16.247

The account will reach a balance of $3200 after about 16 1/4 years.
