Answer:

x = 10°

y = 14

Step-by-step explanation:

Angle A = angle B = angle C = 6x ( equilateral triangle has equal angles )

therefore

Angle A + Angle B + angle C = 180° ( sum of angle in a triangle)

6x + 6x + 6x = 180

18x = 180°

divide both sides by 18

x = 10°

to get y

side AC = AB = BC ( equilateral triangle has equal sides )

Answer: The sum that will be the upper limit of this population is 1280.

Step-by-step explanation:

Since we have given that

Initial population a₁ = 960

Common ratio = $\frac{1}{4}$

So, We have to write the sum in sigma notation:

$\sum (ar^{n-1})\\\\=\sum 960(\frac{1}{4})^{n-1}\\\\$

Since $r=\frac{1}{4}$

so, the sum is convergent, then,

$\sum 960(\frac{1}{4})^{n-1}=\frac{a}{1-r}=\frac{960}{1-\frac{1}{4}}=\frac{960}{\frac{3}{4}}=\frac{960\times 4}{3}=320\times 4=1280$

Hence, the sum that will be the upper limit of this population is 1280.

Evaluate the function f(x) = 2x3 - 6x + 1 for f(-2).

erma4kov [3.2K]

Answer:

- 3

Step-by-step explanation:

$f(x) = 2 {x}^{3} - 6x + 1 \\ plugging \: x = - 2 \\ f( - 2) = 2( { - 2})^{3} - 6( - 2)+ 1 \\ = 2 \times ( - 8) + 12 + 1 \\ = - 16 + 13 \\ = - 3 \\ f( - 2) = - 3$
