5 x 5 x 5
Expanded just means writing it out as you would solve it. So solving a cube would be multiplying the number by itself 3 times

5x5x5 =125 because it's 25x 5

Reflect 4, 1 in the x-axis

Marysya12 [62]

Hello there,

When you reflect a point over the x-axis the x-coordinate stays the same while the y-coordinate is its opposite.

In the given point (4,1) when it is reflected over the x-axis you would get (4, -1).

Hope I helped,

Explain how knowing that 5÷8=0.625 helps you write the decimal for 4 5/8

bonufazy [111]

When you trying to write the decimal value of 4 5/8 then you will get 4+ 5/8. If you know how much 5/8 value in decimal form then you don't need to divide 5 with 8. You just need to convert it separately, make it become 4+0.625 = 4.625.

Since you are skipping a stage it definitely helps and making you write the decimal faster.

Exponential function

laiz [17]

A typical exponential function is y=a $b^{x}$
when x=3.5, y=16.2
when x=6, y=3936.6
plug these values into the exponential function:
16.2=a $b^{3.5}$
3936.6=a $b^{6}$
divide the second equation by the first to eliminate a:
243= $b^{(6-3.5)}$
log both sides: log243=2.5logb
logb=log243/2.5
use your calculator to find b: b=3.6
plug b=3.6 in the first equation to find a:
16.2=a $* (3.6)^{3.5}$
a=0.183

please double check my calculation
