Which of the equations are true identities?
A. (9k – 8)(9k + 8) = 81k2 + 64
B.(3m +2n)(6m – 4n) = 18m²
18m2 – 8n?
Choose 1 answer:

Answers

Answer:

We have two expressions, let's see if they are true or not:

A: (9k - 8)*(9k + 8) = 81*k^2 + 64

To prove this, we only need to start in the left side and see if we can construct the right side:

(9k - 8)*(9k + 8) = (9k)*(9k) + (9*k)*8 - (9k)*8 + 8*(-8)

                         = (9k)^2 - 8^2

                         = 9^2*k^2 - 64  = 81*k^2 - 64

This is different than the thing in the original equation, then this one is not an identity.

B) (3m +2n)(6m – 4n) = 18m^2 – 8n

Same as before, we start at the left side and work it out.

(3m + 2n)*(6m - 4n) = (3m)*(6m) + (3m)*(-4n) + (2n)*(6m) + (2n)*(-4n)

                                = 18*m^2  -12*m*n + 12*m*n - 8*n^2

                                = 18*m^2 - 8*n^2

Notice that here we have an "n^2" while in the original equation we have only an "n".

This may be an error in the question and the exponent is missing, in that case, this equation would be an identity, but it is not as how is written in the question.

Then neither A nor B are correct.

Find the area and perimeter of the shaded region. Stuck on this one can someone help me

Answers

Answer:

perimeter-

perimeter outer rectangle = 2 (l+b)

=2×8+9

= 2×17

2×17 =34 cm sq.

perimeter of inner rectangle = 2 (l+b)

= 2×5+3

=2× 8

= 16 cm sq.

perimeter of shaded portion= 34 - 16

= 18 cm sq.

area-

area of inner rectangle =l×b

l×b = 3×5

3×5=15

15 cm sq.

area of outer rectangle =l×b

l×b= 9×8

9×8= 72

72 cm sq.

area of shaded portion = 72 -15 =57 cm sq.

hey there! In second method i have done first area of inner rectangle but you have to do first area of outer rectangle...

hope it helps you....

Answer:

Let A1 = be the large rectangle and A2 the small rectangle

=> Area A1: S1 = a1.b1 => S1 = 8 x 9 = 72m2

=> Area A2: S2 = a2.b2 => S2 = 3 x 5 = 15 m2

=> Area of the remaining surrounding square: S1-S2 = 72-15 = 67m2

=> Perimeter A1: P1 = 2 (a1 + b1) = 2 (9 + 8) = 34m

=> Perimeter A2: P2 = 2 (a2 + b2) = 2 (3 + 5) = 16m

=> Perimeter of the surrounding square: P1-P2 = 34-16 = 18m

Slope (x) is rise/run. From one intersecting point to the next, we find it is moving 4 y down and 1 x over. Using this we conclude the slope is -4/1x (or -4x)

The second number in the system is b, or y-intercept. The line intercepts at 4y. If we combine these together, the outcome is y = -4x + 4

The distance traveled by a snowball thrown straight down from the top of a bluff can be calculated with the equation d=ut+12gt2, where d is the distance traveled in meters, u is the initial velocity in meters per second, t is the time in seconds, and g is the acceleration due to gravity, which is 9.8ms2. If the snowball traveled 200 meters in 5 seconds, what was its initial velocity?

Answers

Answer:

15.5 m/s

Step-by-step explanation:

Using the equation, d = ut+1/2gt² where all the variables have meaning as given above, making u subject of the formula, we have

d = ut+1/2gt²

d - 1/2gt² = ut

d/t - 1/2gt²/t = u

u = d/t - 1/2gt

Since d = 200 m, t = 5 s and g = 9.8m/s², substituting the values of the variables into the equation, we have

u = d/t - 1/2gt

u = 200 m/5 s - 1/2 ×  9.8m/s² × 5 s

u = 40 m/s - 49 m/s ÷ 2

u = 40 m/s - 24.5 m/s

u = 15.5 m/s

So, the initial speed of the snowball is 15.5 m/s

The angle between the two sides of the right triangle is aproximately 31.003º.

Step-by-step explanation:

From image attached on question we infer that we need to find the angle between sides of lengths 6 (adjacent leg) and 7 (hypotenuse) in the right triangle. The angle can be found by means of this trigonometric ratio:

[tex]\cos \alpha = \frac{6}{7}[/tex]

[tex]\alpha = \cos^{-1} \frac{6}{7}[/tex]

[tex]\alpha \approx 31.003^{\circ}[/tex]

The angle between the two sides of the right triangle is aproximately 31.003º.

In a survey of 800 people, 32% preferred cats and 27% preferred dogs. How many more people preferred cats than preferred dogs?

Answers

Calculate the amount of people on both sides.

32% preferred cats

32% of 800

0.32 × 800 = 256 people

27% preferred dogs

27% of 800

0.27 × 800 = 216 people

So 256 people preferred cats and 216 people preferred dogs.

256 - 216 = 40 people

40 more people preferred cats than preferred dogs

40 people preferred cats more than preferred dog.

What is percentage?

Percentage is a measurement to find value of given number out of hundred.

Given that,

Total number of people participated in survey = 800.

Percentage of people who preferred cats = 32%,

And percentage of people who preferred dogs = 27%.

The percentage of  people who preferred cats more than preferred dogs

= 32 - 27

= 5 %

The number of people preferred cats more than preferred dogs

= 800 x 5/100

= 40.

There are 40 more people preferred cats than dog.

The path of a diver diving off a 10-foot platform can be represented by the function h(x) = - 0.5(x^2 - 4x - 21) where h is the diver's height above water and x is the horizontal distance from the platform (in feet).

What does the positive zero represent?

Answers

Answer:

x = -3 and 7

Step-by-step explanation:

Given the path of a diver expressed as;

h(x) = - 0.5(x^2 - 4x - 21)

The positive zero occur at when h(x) = 0

Substitue

0  = - 0.5(x^2 - 4x - 21)

-0.5x^2 + 2x + 10.5 = 0

Multiply through by -10

5x^2 - 20x - 105 = 0

x^2 - 4x - 21 = 0

x^2 - 7x+3x - 21 = 0

x(x-7)+3(x-7) = 0

(x+3)(x-7) = 0

x = -3 and 7

Hence the positive zero displacement occurs at x = -3 and 7
