Which statement is true regarding the graphed functions?

Mathematics
1 answer:
dangina [55]3 years ago
5 0

You need to translate each function statement into a point.

If f(0)=2, then (0,2) has to be on the graph of f.  It's not, so that rules out option #1.

Do the same for the other statements to figure out which one correctly identifies a point on each graph.

Answer:

Solution given:

here

by using Pythagoras law

hypotenuse =

\displaystyle\sqrt{adjacent ²+opposite ²}\\=\sqrt{15²+36²}=39

Cos C=\frac{adjacent} {hypotenuse}=\frac{15}{39}=\frac{5}{13} or{0.38}

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

What is the solution to this system of linear equations?
Readme [11.4K]

Answer:

(7,3)

Step-by-step explanation:

you can add the equations together to eliminate y and first solve for x

(x-3y = -2) + (x+3y=16) = (2x = 14)

x = 7

then plug x into one of the equations to solve for y

(7) - 3y = -2

9 = 3y

y = 3

the solution is (7,3)
