CW: A sheet measures 20cm by 50cm. How many sheets

Mathematics

1 answer:

Oxana [17]3 years ago

4 0

Answer:

200 sheets are required

Step-by-step explanation:

We need to calculate the area of both the sheets and the wall

Mathematically,

area of a rectangle = l * b

Area of the sheet = 20 * 50 = 1,000 cm^2

100cm = 1 m

so the area of the wall is 400 by 500 = 200,000 m^2

To know the number of sheets, we now divide the area of the wall by that of the sheet

Mathematically, that will be;

200,000/1,000 = 200 sheets

What is the vertex of the graph of f(x) = 4(x+5)²-1?

vodomira [7]

Answer:

The vertex is (-5,-1)

Step-by-step explanation:

f(x) = 4(x+5)²-1

This is written in vertex form

y = a(x-h)^2 +k where ( h,k) is the vertex

f(x) = 4(x- -5)²-1

H is -5 and k = -1

The vertex is (-5,-1)

Simplify radical using the exponent rule. Show work

katen-ka-za [31]

Answer:

$\frac{1}{x^{4} }$

Step-by-step explanation:

( $\sqrt[3]{x^{2} }$ × $\sqrt[6]{x^{4}}$ )⁻³

$\sqrt[3]{x^{2} }$ is the same thing as $x^{\frac{2}{3} }$

you can think of the numerator as the power and the denominator as the root

rewrite both terms:

( $x^{\frac{2}{3} }$ × $x^{\frac{4}{6} }$ )⁻³

simplify the 4/6:

( $x^{\frac{2}{3} }$ × $x^{\frac{2}{3} }$ )⁻³

bases are the same, add the exponents:

( $x^{\frac{4}{3} }$ )⁻³

multiply the exponents:

$x^{\frac{-12}{3} }$

simplify:

x⁻⁴

negative power rule:

$\frac{1}{x^{4} }$
