Y varies directly with x. If y = 15 when x = -18, find y when x = 1.6.

Someone please help me! I’ve been stuck on this forever!

Answers

Answer 1

Answer:

y = -4/3

Step-by-step explanation:

A direct variation equation has the form

y = kx

We need to find the value of k for this situation.

For that, we use the given values of x and y and solve for k.

When x = -18, y = 15.

15 = k × -18

k = 15/(-18)

k = -5/6

Now that we know the value of k for this specific situation, we write the equation of direct variation for our case.

y = -5/6 x

Finally, we find y when x = 1.6 using our equation.

y = -5/6 x

y = -5/6 × 1.6

y = -8/6

y = -4/3

Monica has 2 gallons of milk to make milkshakes. Each milkshake contains 1 cup of milk. There are 128 ounces in 1 gallon and 8 ounces in 1 cup.

How many cups of milk does Monica have to make milkshakes? .

Answers

Answer: 32 cups of milk

Step-by-step explanation:

The first thing to do is to convert the gallons of milk to milkshakes so that you are able to convert easier to cups.

There are 128 ounces in 1 gallon and Monica has 2 gallons. The amount of milk Monica has in ounces is:

= 128 * 2

= 256 ounces

Each cup is capable of holding 8 ounces and there are 256 ounces available so the number of cups of milk is:

= 256 / 8

= 32 cups of milk

answer:

A, D, E

step-by-step explanation:

in order to find the range, you have subtract the smallest number from the largest number in the set of values you are given

A — 13 - 1 = 12

B — 15 - 7 = 8

C — 12 - 12 = 0

D — 28 - 16 = 12

E — 36 - 24 = 12

F — 29 - 25 = 4

i took each of the set of values and subtracted the smallest from the largest and got that A, D and E give me 12 for the range

13. Whats the domain and range?
14. What’s the domain and range?

Answers

Answer:

See below

Step-by-step explanation:

13) Domain: x -> {-3,-2,-1,0,1,2}, Range: f(x) -> {5}

14) Notice how x can't be -4 as that will make the denominator 0. Therefore, your domain is (-∞,-4)U(-4,∞) and your range is [0,∞) since 0 is the lowest possible real y-value that satisfies the equation (recall that if y<0, you are unable to find the real square root of a real number)

Cual es la magnitud de la aceleración angular de una llanta de un automóvil que adquiere una velocidad angular de 350 rad/s en 2 segundos?

Answers

Respuesta:

175 rad / s²

Explicación paso a paso:

Dado que :

Velocidad angular final = 350 rad / s

Tiempo empleado = 2 segundos

La aceleración angular, a =?

Recordar ; la aceleración angular es igual a la carga en velocidad angular con el tiempo

(velocidad final - Velocidad inicial) / tiempo empleado

Velocidad inicial = 0 rad / s

Aceleración angular = (350 - 0) / 2 = 350/2

= 175 rad / s²
