Reading a coordinate graph
Coordinates (x, y)
Slope Formula: $\displaystyle m = \frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Identify points from graph

Point (-5, -3)

Point (3, 1)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [Slope Formula]: $\displaystyle m = \frac{1--3}{3--5}$
[Fraction] Subtract: $\displaystyle m = \frac{4}{8}$
[Fraction] Simplify: $\displaystyle m = \frac{1}{2}$

Answer:

Step-by-step explanation:

–

q+6)=

–

5q–30=

–

Add -5 to both sides

Subtract -5 from both sides

Multiply both sides by -5

Divide both sides by -5

Apply the distributive property

5q=

Add 30 to both sides

Divide both sides by 5 would be 69

If f(x) = 2x^2 + 2, find f(5)

zlopas [31]

Well, following the order of PEMDAS, I got choice B. 52

For instance, when you plug in 5 for x, you get F(5)=2(5)^2+2.

Moreover, following PEMDAS, you're supposed to solve what's inside the parenthesis, but since there is no operation going on inside the parenthesis, then you simple move on to the exponent.

In this case, you square the number 5, which gives you F(5)=2(25)+2

After that, you Multiply (letter M in PEMDAS). This results in F(5)=50+2.

Finally, you add them, which results in F=52.

By the way, I noticed a mistake in your work. When multiplying 2 by 5, the answer is 10, not 20.

Anyway, hope this helped! :-)

Answer:

h = 7.1 cm

Step-by-step explanation:

To find the height of the triangle, we can first find the area of the triangle using the Heron's formula:

$S = \sqrt{p(p-a)(p-b)(p-c)}$

Where a, b and c are the sides of the triangle and p is the semi perimeter of the triangle:

$p = \frac{a+b+c}{2} = \frac{15 + 8 + 17 }{2} = 20\ cm$

So the area of the triangle is:

$S = \sqrt{20(20-15)(20-8)(20-17)}$

$S = 60\ cm^2$

Now, to find the height, we can use the following equation for the area of the triangle:

$S = base * height/2$

The height draw in the figure is relative to the side of 17 cm, so this side is the value of base used in the formula. So we have that:

$60 = 17 * h/2$

$h = 120/17$

$h = 7.06\ cm$

Rounding to the nearest tenth, we have h = 7.1 cm
