Which point has coordinates (0, -5) ?

1 answer:

inysia [295]2 years ago

3 0

Answer:

Hi the point that has the coordinates of (0, -5) is point •W ( The LIGHT GREEN one ).

Step-by-step explanation:

The reason one why it's point •W ( The LIGHT GREEN one ) is because it's still on the line which is the y-axis and also because it's on -5. Sorry I'm not that good at explaining things

Simplify the ration expression
$\frac{3x-6}{x-2}$

start by seeing if anything in the numerator or denominator can be factored,
you should notice that you can factor out a 3 from 3x-6 in the numerator

when you do so, the result is
$\frac{3 *(x-2)}{x-2}$

now, since there is an x-2 in the numerator and denominator, they "cancel" out since

$\frac{x-2}{x-2} =1$
however, only when $x \neq 2$
since $\frac{0}{0} \neq 1$

when you cancel out the x-2, you're left with 3

hence, your answer is C

Surface area of a sphere is 615.752 m2, what is the volume of the sphere?

const2013 [10]

B

the volume (V) of a sphere = $\frac{4}{3}$ πr³

We require to know the radius r to calculate the volume

using surface area of a sphere = 4πr² = 615.752

divide both sides by 4π

r² = $\frac{615.752}{12.56}$ = 49.0248...

take the square root of both sides

r = $\sqrt{49.0248..}$ ≈ 7, hence

V= $\frac{4}{3}$ × π × 7³ = 1436.76 m³ → B

Which proportion could be used to find the length of side b?

Goshia [24]

Answer:

B

Step-by-step explanation:

Using the Sine Rule in ΔABC

$\frac{a}{sinA}$ = $\frac{b}{sinB}$ = $\frac{c}{sinC}$

∠C = 180° - (82 + 58)° = 180° - 140° = 40°

Completing values in the above formula gives

$\frac{a}{sin58}$ = $\frac{b}{sin82}$ = $\frac{8.4}{sin40}$

We require a pair of ratios which contain b and 3 known quantities, that is

$\frac{b}{sin82}$ = $\frac{8.4}{sin40}$

OR

$\frac{sin40}{8.4}$ = $\frac{sin82}{b}$ → B

In centimeters, what is the unknown length in this right triangle

Ilya [14]

Answer:

11

Explanation:

(next time, it would be helpful to include a picture)

If you were on the same test as I was, than that means that the triangle you're looking for is the one below.

Using the Pythagorean Theorem,

a² + b² = c² is the same as c² - b² = a²

c = 61

61^2 = 61 X 61 = 3,721

b = 60

60^2 = 60 X 60 = 3,600

Next, we subtract:

3,721 - 3,600 = 121

√121 = 11

(x = 11 cm)

so 11 is your answer

Determine the missing number in the equation 13-2=12-?

soldier1979 [14.2K]

For the equation to work, you have to have the same number on both sides of the equal sign

so to find ?, you can do:

13 - 2 = 12 - ? Simplify

11 = 12 - ? Subtract 12 on both sides

-1 = - ? Multiply -1 on both sides

1 = ?
