Answer:

1,-1

Step-by-step explanation:

because section be is for +,-

Answer:

1,-1

Step-by-step explanation:

Given:

The radius of the cylinder = 2 cm

Height of the cylinder = 5 cm

To find:

The volume of the cylinder.

Solution:

We know that, the volume of a cylinder is:

[tex]V=\pi r^2h[/tex]

Where, r is the radius and h is the height of the cylinder.

Putting [tex]r=2,h=5[/tex] in the above formula, we get

[tex]V=\pi (2)^2(5)[/tex]

[tex]V=\pi (4)(5)[/tex]

[tex]V=20\pi [/tex]

Therefore, the volume of the cylinder is [tex]20\pi [/tex] cubic cm and its approximate value is 62.832 cubic cm.

Answer:

y = 6

Step-by-step explanation:

(y + 6) × y = 72

y = negative number²

When negative numbers are squared they become positive.

y = 6

Check

(6 + 6) × 6 = 72

12 × 6 = 72

Step-by-step explanation:

P(-4,7)

Q(-1,-1)

R(-8,-1)

Answer:

[tex]\frac{1}{6}[/tex]

Step-by-step explanation:

6 sides, so 6 is the denominator.

There is only one 1, so the numerator is 1.

Therefore p(1) = [tex]\frac{1}{6}[/tex]

Answer:

31

Step-by-step explanation:

a + (n-1)d  where a = first term;  n = which number we want;  d = common difference.

=> 4 + (10 - 1)3

=> 4 + (9)*3

=> 4 + 27

=> 31

Answer:

2

Step-by-step explanation:

Answer:

A = 70 units²

Step-by-step explanation:

Since all 4 sides are congruent then figure is a rhombus

The area (A) of a rhombus is calculated as

A = [tex]\frac{1}{2}[/tex] × d₁ × d₂ ( d₁ and d₂ are the diagonals )

Here d₁ = 7 + 7 = 14 and d₂ = 5 + 5 = 10 , then

A = [tex]\frac{1}{2}[/tex] × 14 × 10 = 7 × 10 = 70 units²

Step-by-step explanation:

% Increase = ((New value - Old Value) / Old Value) * 100

Given New value = $85

and Old Value = $35

% Increase =

[tex] (\frac{85 - 35}{35} ) \times 100 \\ = ( \frac{50}{35} ) \times 100 \\ = 143percent(nearest \: whole \: number)[/tex]

5 (x + 8)

Root:

x = -8

Derivative:

d/dx(2 x + 46 + 3 x - 6) = 5

Indefinite integral:

integral(40 + 5 x) dx = (5 x^2)/2 + 40 x + constant

Answer:

5x-40=0

5x=40

x=40/5

x=8

Answer:7348 is already in the simplest form. It can be written as 1.520833 in decimal form (rounded to 6 decimal places).

Step-by-step explanation:

Answer: it’s already at its lowest form

Step-by-step explanation:

Answer: Divide the chord length by double the radius.

Find the inverse sine of the result.

Double the result of the inverse sine to get the central angle in radians.

Once you have the central angle in radians, multiply it by the radius to get the arc length.

Answer:

Step-by-step explanation:

Divide the US population by the world population:

328,200,000/7,674,000,000 = 0.0428

Multiply 0.0428 with 100:

0.0428 x 100 = 4.28

Approximately 4 out of 100 people in the world would live in the USA.

Answer:

Bounty Paper Towels is the better deal

Step-by-step explanation:

8.49 divided by 8 = 1.06125 ($1.01)

13.99 divided by 12 = ~1.16583 ($1.16)

The Brawny is more expensive per roll, so Bounty would be a better deal

Answer:

cos 25° = X/11

and

sin 65° = X/11

is this good enough or do you need more workings?

Answer:

C = 90°

Step-by-step explanation:

The interior angles in every triangle are equal to 180 degrees. So, this means that

[tex] \alpha + \beta + \gamma \\ = 180 \: degrees[/tex]

Which means that A + B +C = 180 degrees

A=25°

B = 65°

C =?

C = 180° - (A + B)

C = 180° - (25° +65°)

C = 180° - 90°

C = 90°

Answer:

113.04 ft³ is correct

Step-by-step explanation:

The volume (V) of a cone is calculated as

V = [tex]\frac{1}{3}[/tex]πr²h ( r is the radius and h the height )

There are 2 cones to be summed one with h = 7 , the other with h = 5

Thus

V = [tex]\frac{1}{3}[/tex] π × 3² × 7 + [tex]\frac{1}{3}[/tex]π × 3² × 5

   = [tex]\frac{1}{3}[/tex] × 3.14 × 9 (7 + 5)

   = 3.14 × 3 × 12

   = 113.04 ft²

Answer:

x = 8

Step-by-step explanation:

a² + b² = c²

x² + 15² = 17²

x² + 225 = 289

x² = 289 - 225

x² = 64

[tex]\sqrt{x^2} =\sqrt{64}[/tex]

x = 8

Answer:

The person solving the problem first subtracted 6 from 15. Since the cube root is next to the six, the problem should be read as [tex]15-6(\sqrt[3]{\frac{-1000}{27} } )[/tex] rather than [tex](15-6)(\sqrt[3]{\frac{-1000}{27} } )[/tex].

please lmk if anything is wrong with my answer, hope this helps :)
