Eek help? im a bit confused
Ahat [919]

Answer:

3 3/4

Step-by-step explanation:

Each block is worth 0.5 cm (1/2)

One note - NEVER FORGET THE UNITS

L - 5 blocks (5 blocks × 0.5cm = 2.5cm)

W - 2 blocks (2 blocks × 0.5cm = 1cm)

H - 3 blocks (3 blocks × 0.5cm = 1.5cm)

Formula for Volume:

V = L × W × H

V = 2.5cm × 1cm × 1.5cm = 3.75cm (fraction can be 3 3/4)

You're welcome :)

What equation represents a line that passes through (4,1/3) and has a slope of 3/4
AysviL [449]
\bf (\stackrel{x_1}{4}~,~\stackrel{y_1}{\frac{1}{3}})
\qquad \qquad \qquad \qquad 
% slope  = m
slope =  m\implies \cfrac{3}{4}
\\\\\\
% point-slope intercept
\stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-\cfrac{1}{3}=\cfrac{3}{4}(x-4)\implies y-\cfrac{1}{3}=\cfrac{3}{4}x-3
\\\\\\
y=\cfrac{3}{4}x-3+\cfrac{1}{3}\implies y=\cfrac{3}{4}x-\cfrac{8}{3}

A square has a side that is (x-3) units long. If the area of the square is 126.5625 sq units, what is the value of x?
Kitty [74]

Answer:

14.25 units

Step-by-step explanation:

Area of a square= l*b= (x-3)(x-3)=x^{2}-3x-3x+9=x^{2}-6x+9

x^{2}-6x+9=126.5625

x^{2}-6x-117.5625

Solving the equation using quadratic equation then as attached

x=14.25 units

To prove

x-3=14.25-3= 11.25 units

area=11.25*11.25=126.5625 sq units

Solve x^2 + x - 12 = 0
bogdanovich [222]

Answer:

x₁ = -4

x₂ = 3

Step-by-step explanation:

x²+ x + 12 = 0

x = {-1±√((1²)-(4*1*-12))} / (2*1)

x = {-1±√(1+48)} / 2

x = {-1±√49} / 2

x = {-1±7} / 2

x₁ = {-1-7} / 2 = -8/2 = -4

x₂ = {-1+7} / 2 = 6/2 = 3

Check:

x₁

-4² + (-4) - 12 = 0

16 - 4 - 12 = 0

x₂

3² + 3 - 12 = 0

9 + 3 - 12 = 0

If f(x) = x-1/3 and g(x)= 3x+1, what is (f o g)(x)?
N76 [4]

Answer:

(f o g)(x) = 3x + \frac{2}{3}

Step-by-step explanation:

We have the function f(x) = x-\frac{1}{3} and we have the function g(x) = 3x + 1. We want to find g(x) composed with f(x)

Then, the function (f o g)(x) is the same since f(g(x))

That is, you must do x = g(x) and then enter g(x) into the function f(x).

f(g(x)) = (g(x)) -\frac{1}{3}

f(g(x)) = (3x + 1) -\frac{1}{3}

Simplifying, we obtain:

(f o g)(x) = 3x + 1 -\frac{1}{3}\\\\(f o g)(x) = 3x + \frac{2}{3}

Finally. The composite function is:

(f o g)(x) = 3x + \frac{2}{3}
