The diameter of the circle is 10 units what is the radius of the circle

gayaneshka [121]

Answer:

Radius is 5 units

Step-by-step explanation:

The radius of a circle will always be 1/2 of the diameter.

This gives the formula:

$r=\frac{d}{2}$

(substitute known values)

$r=\frac{10}{2}$

(divide 10 by 2)

$r=5$

Therefore the radius is five

An engineer deposits $2,000 per month for four years at a rate of 24% per year, compounded semi-annually. How much will he be ab

Alex17521 [72]

The amount of money he will be able to withdraw after 10 years after his last deposit is $926,400.

<h3>Compound interest</h3>

Principal, P = $2,000 × 12 × 4

= $96,000

Time, t = 10 years
Interest rate, r = 24% = 0.24
Number of periods, n = 2

A = P(1 + r/n)^nt

= $96,000( 1 + 0.24/2)^(2×10)

= 96,000 (1 + 0.12)^20

= 96,000(1.12)^20

= 96,000(9.65)

= $926,400

Therefore, the amount of money he will be able to withdraw after 10 years after his last deposit is $926,400

PLEASE HELP ME RN PLEASE

Advocard [28]

Answer:

$\frac{n^{2} - 1 }{2}$

$\sqrt{29}$

Step-by-step explanation:

Area of triangle=1/2×b×h

$\frac{1}{2} \times (n - 1)(n + 1)$

$\frac{( {n}^{2} + n - n - 1) }{2 }$

$\frac{ {n}^{2} - 1 }{2}$

2. Area of triangle=14

$\frac{ {n}^{2} - 1 }{2} = 14$

${n}^{2} - 1 = 28$

${n}^{2} = 29$

$n = \sqrt{29}$

please rate well and mark BRAINLIEST.
