Answer:

Grayson has to walk 1.7 miles across the field.

Step-by-step explanation:

We have drawn the diagram for your reference.

Given:

Grayson usually walks 1.5 miles west on the side walks

According to Diagram we can say;

CA = 1.5 miles

Also Given:

Grayson also walks 0.8 miles north on the sidewalks

So According to Diagram we can say;

BA =0.8 miles

Now we need to find number of miles Grayson have to walk across the field.

According to diagram we can say;

We have to find CA.

Assuming the diagram to be right angled triangle.

We can find CA using Pythagoras theorem.

${CA}^2 = {CB}^2+{BA}^2$

Substituting the given values we get;

${CA}^2 =1.5^2+0.8^2 = 2.25 +0.64 =2.89$

Taking square root on both side we get;

$\sqrt{{CA}^2} = \sqrt{2.89} \\\\CA = 1.7 \ mi$

Hence Grayson has to walk 1.7 miles across the field.

MA 912. G.1.4

Answer:

Step-by-step explanation:

Going from (1, -2) to (3,6), x increases by 2 and y increases by 8. Thus, the slope m of this line is m = rise / run = 8/2 = 4.

I think you meant, "What is the EQUATION of the line that passes through the point (-1, 1) and is parallel to a line that passes through

(3, 6) and (1, -2)? We have seen that this slope is -4.

Starting with the point-slope equation of a line, we have:

y - 6 = -4(x - 3)

What is the solution?. 1/2x2 – x + 5 = 0

AfilCa [17]

1/2 x^2 - x + 5 = 0
Multiply through by 2 to get:
x^2 - 2x + 10 = 0
$x= \frac{-b\pm\sqrt{b^2-4ac}}{2a}$ ; where a = 1, b = -2 and c = 10
$x=\frac{-(-2)\pm\sqrt{(-2)^2-(4\times1\times10)}}{2\times1}\\=\frac{2\pm\sqrt{4-40}}{2}\\=\frac{2\pm\sqrt{-36}}{2}\\=\frac{2\pm6i}{2}\\=1\pm3i$
Therefore, x = 1 + 3i or x = 1 - 3i
