25^2 = 20^2 + 15^2
625 = 400 + 225
625 = 625

It's a right triangle.

Its a RIGHT ANGLED TRIANGLE.

GIVEN:
hypo=25
opposite and adjacent=15 and 20.

FORMULA:
hypotenuse^2 =opposite side^2 + adjacent side^2
25^2=15^2+20^2
625=225+400
400+225=625

so its a right angled triangle....................

Solve for x 5^x= 3x^x+1

Stella [2.4K]

Answer:

x=1

Step-by-step explanation:

5 − 3 x = x + 1

Move all terms containing x to the left side of the equation.

5 − 4 x = 1

Move all terms not containing x to the right side of the equation. − 4 x = − 4

Divide each term by − 4 and simplify.

x = 1

If r=0.5 and a6=0.03125 what is the value of a1?

andre [41]

I guess this is a geometric series:

a6 = a1 * r^5 so

a1 = 0.03125 / 0.5^5

= 1 answer

The table represents a linear function. What is the slope of the function?

TEA [102]

Answer:

-4

Step-by-step explanation:

The function is linear; therefore, the slope of the line joining any two points is the same.

We take any two points from the table and compute the slope or rise/ run between them— let is take points (-4, -2) and (-2, -10).

The slope $m$ of the line joining the points is

$m=\dfrac{\Delta y }{\Delta x } =\dfrac{-2-(-10)}{-4-(-2)} \\\\\boxed{m=-4}$

The slope of the function is -4.
