Answer:

The Greatest Common Factor (GCF) for 56 and 84, notation CGF(56,84), is 28.

Step-by-step explanation:

The factors of 56 are 1,2,4,7,8,14,28,56;

The factors of 84 are 1,2,3,4,6,7,12,14,21,28,42,84.

So, as we can see, the Greatest Common Factor or Divisor is 28, because it is the greatest number that divides evenly into all of them.

The square root of 73. Since the theorem is a^2+b^2=c^2 and only works with right triangles. You take 2/2 the base so you have a right triangles with a hypotenuse if 9 and a side of 3. Then you just plug in to solve.

AleksandrR [38]

Answer:

59 minutes

Step-by-step explanation:

In the table of values it is observed that for each day of training 2 minutes are increasing and that day 1 begins with 5 minutes of training , so

$y(x)=2\frac{min}{d}(x)+3min$ , where x= evaluation day

we have to for the day 28

$y(28)=2\frac{min}{d}(28d)+3min=59min$

Are the triangles similar? If so, explain why.<br> АД<br> 3462

Alchen [17]

<em>Greetings from Brasil...</em>

Just 2 equal angles are enough for the triangles to be similar .... The second triangle has the same angles as the first.

We know that the sum of the internal angles of a triangle is 180, so for the second triangle:

84,6 + 65 + X = 180

X = 180 - 84,6 - 65

X = 30,4 → same angle as the largest triangle

So we have AA~ similarity

Find the equation of the line through the points (0, –3) and (4, 5)

vekshin1

Answer:

y=2x-3

Step-by-step explanation:

Hi there!

We are given the points (0, –3) and (4, 5)

We want to find the equation of the line between these points

There are 3 ways to write the equation of the line, yet the most common way is slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept

To write the equation of the line in this way, we need to first find the slope of the line
The slope can be found using the formula $\frac{y_2-y_1}{x_2-x_1}$ , where $(x_1, y_1)$ and $(x_2, y_2)$ are points

We already have 2 points, but let's label their values to avoid confusion and mistakes when calculating.

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

m= $\frac{5--3}{4-0}$

Simplify

m= $\frac{5+3}{4-0}$

m= $\frac{8}{4}$

Divide

m=2

We found the slope of the line.

Here is the equation of the line so far:

y=2x+b

Now let's find b

As stated before, b is the y intercept of the line, which is the point where the line passes through the y axis; the value of x at the y intercept is 0

One of the points we were given (0, -3) is actually the y intercept of the line!

The value of b is the value of y at the y intercept; in this case, b is equal to -3

Now substitute -3 as b in the equation.

y=2x-3

Hope this helps!
