Based on the information given and the computation, the height of the goalpost will be 16.10 meters.

<h3>Solving the equation.</h3>

Let the height of the goalpost be represented by x.

Based on the information given, the equation to solve the question will be:

1.55/1.15 = x/11.95

Cross multiply

1.55 × 11.95 = x × 1.15

x = (1.55 × 11.95) / 1.15

x = 16.10

Therefore, the height of the goalpost will be 16.10 meters.

Write an equation of the line, in slope-intercept form, that passes through (-2, 5) and (1, -1).

djyliett [7]

Answer:

y = -2x + 1

Step-by-step explanation:

Formulae:

Slope: $m=\frac{y_2-y_1}{x_2-x_1}\\$

m = slope
y₂ = second y-value
y₁ = first y-value
x₂ = second x-value
x₁ = first x-value

Point-slope form: $y-y_1=m(x-x_1)$

y₁ = first y-value
m = slope
x₁ = first x-value

Slope-intercept form: $y=mx+b$

m = slope
b = y-intercept value

Calculations:

$m=\frac{-1-5}{1-(-2)}\\m=\frac{-6}{3}\\m=-2$

$y-5=-2(x-(-2))\\y-5=-2(x+2)\\y-5=-2x-4\\y=-2x+1$

I was Thinking it out on my art pad
A=(1/2)
bh A=(1/2)*10*12
A=5*12=60 sq cm
4*60=240 sq cm
A=s*s A=10*10=100 sq cm
240+100=340 sq cm
so A
