I will assume the question is log (8x) = 4/3

This means, "The exponent we put on 10 to get 8x is 4/3"

10^(4/3) = 8x

x = [10^(4/3)]/8

x = 2.69

log (8*2.69) = 4/3 ?
log (21.52) = 4/3
1.33 = 4/3
1.33 = 1.33

Complete the equation of the graphed linear function in point-slope form.

The point-slope form:
$y-y_1=m(x-x_1)$
m - slope
x₁, y₁ - the coordinates of a point

It passes through the points (1,-2) and (2,2).
$(1,-2) \\
x_1=1 \\ y_1=-2 \\ \\
(2,2) \\
x_2=2 \\ y_2=2 \\ \\
m=\frac{y_2-y_1}{x_2-x_1}=\frac{2-(-2)}{2-1}=\frac{2+2}{1}=4$

$\boxed{y-(-2)=4(x-1)}$

If you know the diameter of a circle,

arsen [322]

Step-by-step explanation:

a. Area of a circle = πr², where r means radius.

Step 1: converted diameter to radius.

diameter = 2 radius

In other way of writing, radius = $\frac{1}{2}$ diameter.

Step 2: substitute radius into the formula.

Area of a circle = π( $\frac{1}{2}$ d)²

Step 3: substitute π into the formula.

some question is given the value of π), if not substitute 3.14 for π.

Area of a circle = 3.14( $\frac{1}{2}$ d)²

Step 4: substitute d into the formula, then we can solve its area.

b. a. Circumference of a circle = 2πr, where r means radius.

Step 1: converted diameter to radius.

diameter = 2 radius

In other way of writing, radius = $\frac{1}{2}$ diameter.

Step 2: substitute radius into the formula.

C = 2π( $\frac{1}{2}$ d)

Step 3: substitute π into the formula.

some question is given the value of π), if not substitute 3.14 for π.

C = 2(3.14)( $\frac{1}{2}$ d)

Step 4: substitute d into the formula, then we can solve its circumference.

Luke is making pancakes. The recipe calls for 0.5 quart of milk and 2.5 cups of flour. He has 3/8 quart of milk and 18/8 cups of

cupoosta [38]

<span>3/8 ÷ 0.5 = 3/4
2.5 ÷ 18/8 = 2/5

Since 3/4 > 2/5, he has too much milk. He'll get runny pancakes.Hope this helps! =)</span>

You could use sine to find it
sin45 = 8/m
m = 8/sin45
