20. A rectangle has a length of x + 2 meters and a width of 2x - 5. (A.APR.1)

bija089 [108]

Answer:

2(x + 2) + 2(2x - 5) =

2x + 4 + 4x - 10 =

6x - 6

perimeter = 6x - 6

(x+2)(2x - 5) expand the brackets:

2x² - 5x + 4x - 10

area = 2x² - x - 10

area = 6x - 6 = (6 x 5) - 6 = 30 - 6 = 24

perimeter = 2x² - x - 10 = (2 x 5²) - 5 - 10 = (2 x 25) - 5 - 10 = 50 - 5 - 10 = 35

A spinner is half red and half blue. If you spin the spinner twice, what is the probability that you will get red both times?

Usimov [2.4K]

Answer: Probability of getting red both times is $\frac{1}{4}$

Step-by-step explanation:

Since we have given that

A spinner is half red and half blue.

Probability of getting red is given by

$\frac{1}{2}$

Probability of getting blue is given by

$\frac{1}{2}$

Since he spins the spinner twice.

Probability that you will get red both times is given by

$\frac{1}{2}\times \frac{1}{2}\\\\=\frac{1}{4}$

Hence, Probability of getting red both times is $\frac{1}{4}$

abruzzese [7]

If z ⁷ = 128i, then there are 7 complex numbers z that satisfy this equation.

$z^7 = 128i = 2^7i = 2^7e^{i\frac\pi2}$

$\implies z=\sqrt[7]{2^7} e^{i\frac17\left(\frac\pi2+2n\pi\right)}$

(where n = 0, 1, 2, …, 6)

$\implies z = 2 e^{i\left(\frac\pi{14}+\frac{2n\pi}7\right)}$

$\displaystyle\implies z = 2 \left(\cos\left(\frac\pi{14}+\frac{2n\pi}7\right)+i\sin\left(\frac\pi{14}+\frac{2n\pi}7\right)\right)$
