Mathematics
1 answer:
Contact [7]3 years ago
6 0

Answer:

Third and sixt option

Step-by-step explanation:

Applying the distributive property:

(b-2c)(-3b+c)=b(-3b)+b(c)-2c(-3b)-2c(c)

(b-2c)(-3b+c)=-3b^2+bc+6bc-2c^2

Adding like terms:

(b-2c)(-3b+c)=-3b^2+7bc-2c^2

The simplified product has 3 terms (first and second option are not true)

The simplified product has a degree of 2 (third option is true)

The simplified product, in standard form, has exactly 2 negative terms: -3b^2 and -2c^2 (sixth option is true)

The answer should be f(x)=20(2.5)^x

How?

the graph crosses the f(x) axis at 20 but that's common in all 4 equations. However, when x=1, f(x)=50. We have to know try all the equations by substituting these values in ( both sides are equal).

f(x)=20(2.5)^x
substitute f(x)=50, x=1
50=20(2.5)^1
50=20*2.5
50=50

What is the height of cylinder with a surface area of 226.08 square meters and a radius of 3 meters? (Use 3.14 for π.) 27 meters
zalisa [80]
We know that
surface area of cylinder=2*[area of the base]+perimeter of base*height

area of the base=pi*r²
r=3 m
area of the base=pi*3²----> 28.26 m²

perimeter of the base=2*pi*r
r=3 m

perimeter of the base=2*pi*3----> 18.84 m

surface area=226.08 m²
226.08=2*[28.26]+18.84*h----> 18.84*h=226.08-2*28.26
18.84*h=169.56-------> h=169.56/18.84-----> h=9 m

the answer is
9 m
