Which represents the reflection of f(x)=sqrt x over the y axis
zloy xaker [14]

reflection of f(x)=\sqrt{x} over the y axis we get g(x)=\sqrt{-x}

Step-by-step explanation:

We need to find the reflection of f(x)=sqrt x over the y axis

So, reflection over y- axis

If the function f(x) is transformed over y-axis then the new function g(x) will be g(x)= f(-x)

So, finding reflection of f(x)=\sqrt{x} over the y axis we get:

g(x)=\sqrt{-x}

So, reflection of f(x)=\sqrt{x} over the y axis we get g(x)=\sqrt{-x}

Luna mixes 3/4 of orange juice and 3/8 of cranberry juice and then she gave mags 5/8 cup of juice and we have to turn it into an
Gennadij [26K]

Answer: 1/2

Step-by-step explanation:

The question is for us to calculate the amount of juice that's left.

We are told that Luna mixes 3/4 of orange juice and 3/8 of cranberry juice. The amount of juice mixed will be:

= 3/4 + 3/8

= 6/8 + 3/8

= 9/8

= 1 1/8

We are then told that she gave Mags 5/8 cup of juice. The amount of juice that's then left will be:

= 1 1/8 - 5/8

= 4/8

= 1/2

1/2 cup of juice will be left

A home’s value increases at an average rate of 5.5% each year. The current value is $120,000. What function can be used to find
Wewaii [24]

Answer:

y=120,000(1.055)^x

Step-by-step explanation:

we know that

The equation of a exponential growth function is given by

y=a(1+r)^x

where

y is the value of the home

x is the number of years

a is the initial value

r is the rate of change

we have

a=\$120,000\\r=5.5\%=5.5/100=0.055

substitute

y=120,000(1+0.055)^x

y=120,000(1.055)^x

The volume of a sphere is 5,000pi m3. What is the surface area of the sphere to the nearest square meter?
lyudmila [28]
To get the surface area of the sphere, we need to know the radius. Since the volume is given, we can get the radius.
Volume =  \frac{4}{3}π r³
5000πm³ = \frac{4}{3} π r³
5000m³ = \frac{4}{3} r³
5000m³ x 3 = 4r³
\frac{15000m³}{4} = \frac{4r³}{4}<span>
</span>∛3750 = ∛r³

r = 15.536m
r = 15.54m
Since the radius is now known, substitute it directly to the surface area formula
A = 4π x r²
A = 4π x (15.54)²
A= 3,034.67 m² or 3,035 m²
