When karen serves jury duty, she will receive $15 each day for the first three days she serve. After three days, she will receiv

liubo4ka [24]

Karen received $ 213 for 10 days of serving

Solution:

Given that When karen serves jury duty, she will receive $15 each day for the first three days she serve

To find: money received by karen if she served for 10 days

First three days = $ 15 each day

Therefore,

first day = $ 15

second day = $ 15

third day = $ 15

After three days, she will receive $24 each day she serves

4th , 5th, 6th, 7th , 8th , 9th, 10th day = $ 24 each day

If she serves for 10 days,

money received = 15 + 15 + 15 + 24 + 24 + 24 + 24 + 24 + 24 + 24

money received = 3(15) + 7(24)

money received = 45 + 168 = 213

Thus karen received $ 213 for 10 days of serving

A stand is a frustum shape, formed by removing a small square-based pyramid from the top of

kupik [55]

The frustum can be considered as consisting of a square pyramid, less the

cut volume.

The mass of the stand, is approximately 18.60905 kg

Reasons:

The given parameter of the frustum are;

The density of the frustum, ρ = 85 g/cm³

Height of pyramid, h = 9 cm

Side length of base = 10 cm

Height of frustum

By proportional shapes, the side length of the top of the frustum can be found as follows;

$\dfrac{4 \, cm}{9 \, cm} = \dfrac{x}{10 \, cm}$

$x = \dfrac{4 \, cm}{9 \, cm} \times 10 \, cm = 4\frac{4}{9} \, cm$

$V = \dfrac{h}{3} \times \left(B_1 + B_2 + \sqrt{B_1 \times B_2} \right)$

B₁ = 10², B₂ = $\left(4\frac{4}{9} \right)^2$

Therefore;

$V = \dfrac{4}{3} \times \left(10^2 + \left(4\frac{4}{9} \right)^2 + \sqrt{10^2 \times \left(4\frac{4}{9} \right)^2} \right) \approx 218.93$

The volume of the stand, V ≈ 218.93 cm³

Mass = Volume × Density

∴ Mass of the stand, m = 218.93 cm³ × 85 g/cm³ = 18,609.05 grams = 18.60905 kg.

Your answer should be a polynomial in standard form. (x + 5)(x +3)=(x+5)(x+3)

sattari [20]

Answer:

∴(x+5)(x+3) =x²+8x+15

Step-by-step explanation:

Standard form of a polynomial:

Standard of polynomial means that the terms ordered from biggest exponent of variable to lowest exponent of variable.

Example:

$a_nx^n+a_{n-1}x^{n-1}+a_{n-2}x^{n-2}+......$

Given,

(x+5)(x+3)

=x(x+3)+5(x+3)

=x²+3x+5x+15

=x²+8x+15

∴(x+5)(x+3) =x²+8x+15

The degree of the polynomial is 2 and is a one variable polynomial.
