The product (a+b)(a-2b) is a^2 - ab - 2b^2

The product expression is given as:

(a+b)(a-2b)

Expand the bracket

a * a - a * 2b + b * a - b * 2b

Evaluate the product

a^2 - 2ab + ab - 2b^2

Evaluate the like terms

a^2 - ab - 2b^2

Hence, the product (a+b)(a-2b) is a^2 - ab - 2b^2

Answer:

Step-by-step explanation:

|√2-y|=|y-√2|

√2-y=±(y-√2)

when √2-y=y-√2

y+y=√2+√2

2y=2√2

y=√2

when √2-y=-(y-√2)

√2-y=-y+√2

or 0=0

it gives no value of y.

so only possible value is y=√2

The magnitude of the resultant vector is 22.6 m and the direction is 56.8⁰.

Ax = A cosθ

Ay = A sinθ

Ax = 7.7 x cos(27.8)

Ax = 6.81 m

Ay = 7.7 x sin(27.8)

Ay = 3.59 m

Bx = B cosθ

By = B sinθ

θ with respect to x - axis = 90 - 20 = 70⁰

Bx = 16.3 m x cos(70)

Bx = 5.575 m

By = 16.3 m x sin(70)

By = 15.32 m

Vx = Ax + Bx

Vx = 6.81 m + 5.575 m = 12.385 m

Vy = Ay + By

Vy = 3.59 m + 15.32 m = 18.91 m

V = √(Vy² + Vx²)

V = √(18.91² + 12.385²)

V = 22.6 m

tan θ = Vy/Vx

tan θ = (18.91)/(12.385)

tan θ = 1.527

θ = arc tan (1.527)

θ = 56.8⁰

Thus, the magnitude of the resultant vector is 22.6 m and the direction is 56.8⁰.

The option fourth StartFraction 50 divided by 5 Over 100 divided by 5 EndFraction = StartFraction 10 Over 20 EndFraction is correct.

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

Let x be the number.

According to the problem.

50% of x = 10

x = 10 ÷ 50%

= 10×(50/100)

= (50÷5)/(100÷5) = 10/20

a. The exact value of cosθ = -5/√74

b. The exact value of secθ = -√74/5

c. The exact value of cotθ = 5/7

Since the terminal side of the θ is the point, (-5, -7), we need to find the length of the terminal side.

So, r = √(x² + y²) where

So, r = √(x² + y²)

r = √((-5)² + (-7)²)

r = √(25 + 49)

r = √74

Since the trigonometric ratio cosθ = x/r

Substituting the values of x and r into the equation, we have

cosθ = x/r

cosθ = -5/√74

So, the exact value of cosθ = -5/√74

Since the trigonometric ratio, secθ = r/x

Substituting the values of x and r into the equation, we have

secθ = r/x

secθ = √74/-5

secθ = -√74/5

So,  the exact value of secθ = -√74/5

Since the trigonometric ratio cotθ = x/y

Substituting the values of x and y into the equation, we have

cotθ = x/y

cotθ = -5/-7

cotθ = 5/7

The weight of each pie will be 6 and 8 pounds respectively if the ratio of the seeds in these piles 3:4

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

We have:

A greedy hamster hoarded 2 piles of sunflower seeds. Yesterday the ratio of the seeds in these piles was 3:4

Let 3x and 4x are the seeds from the smaller and bigger pile.

= 4x + 2  (greedy hamster placed another 2 pounds of seeds in the bigger pile)

= 3x - 1/4 (ate 1/4 pound from the smaller pile)

4x + 2 = 5x

Because the quantities of seeds in those piles is in the ratio of 5:16

After solving:

x = 2

Smaller pile weight = 3x = 3(2) = 6

Bigger pile wieght = 4x = 4(2) = 8

Thus, the weight of each pie will be 6 and 8 pounds respectively if the ratio of the seeds in these piles 3:4

The compound amount and the interest earned are $13,222.17 and $2,222.17 respectively.

It is defined as the interest on the principal value or deposit and the interest which is gained on the principal value in the previous year.

We can calculate the compound interest using the below formula:

[tex]\rm A = P(1+\dfrac{r}{n})^{nt}[/tex]

Where A = Final amount

          P = Principal amount

          r  = annual rate of interest

          n = how many times interest is compounded per year

          t = How long the money is deposited or borrowed (in years)

We know the formula for continuous compounding:

[tex]\rm A = P(e)^{rt}[/tex]

[tex]\rm A = 11000(e)^{0.023\times8}[/tex]

A = $13,222.17

I = A - P = 13,222.17 - 11000

I  = $2,222.17

Thus, the compound amount and the interest earned are $13,222.17 and $2,222.17 respectively.

From the information given:

To determine the probability that a randomly selected x-value is in the given interval:

[tex]P(35 < x < 45) = P(\dfrac{35-40}{5} < Z < \dfrac{45-40}{5})[/tex]
