Answer:

f(- 2) = $\frac{1}{8}$

Step-by-step explanation:

To find f(- 2) substitute x = - 2 into f(x) , that is

f(- 2) = 2 $(4)^{-2}$ = 2 × $\frac{1}{4^2}$ = 2 × $\frac{1}{16}$ = $\frac{2}{16}$ = $\frac{1}{8}$

What is the underline value 28 the number 8 is underlined

Troyanec [42]

In the number 28, when 8 is underlined:

8 has the value of simply 8, because it is in the ones place.

Another example would be the 2 in the 8. If the 2 was underlined, because it is in the tens place, the underlined value will be 20

hope this helps

Pedro is building a playground in the shape of a right triangle. The base of the triangle is 18 yards. The height of the triangl

Bezzdna [24]

Answer:

567 square yards

Step-by-step explanation:

The Area for 1 Triangular playground = 1/2 × Base × Height

The base of the triangle is 18 yards. The height of the triangle is 21 yards.

Hence:

= 1/2 × 18 yards × 21 yards

= 189 square yards

The area of the Triangular 3 playground is given as:

= 3 × 189 square yards

= 567 square yards

Write an equation for the line described in standard form with x-intercept 4 and y-intercept 5

stealth61 [152]

Answer:

Equation $( \frac{5}{4}) x + y = 5$ is in the standard dorm.

Step-by-step explanation:

Here, the x - intercept = 4 , so ( 4,0) is a point on the line.

and the y - intercept = 5, so ( 0,5) is a point on the line.

So, the slope of the equation is given as = $\frac{y_2 - y_1}{x_2-x_1 } = \frac{5 -0}{0-4} = -\frac{5}{4}$

Now, the SLOPE INTERCEPT FORM of an equation is :

y = mx + b: here m = slope and b = y- intercept

or, $y =-( \frac{5}{4}) x + 5$

Now, standard form is Ax +By = C

So, the standard form is $( \frac{5}{4}) x + y = 5$

Hence, the above equation $( \frac{5}{4}) x + y = 5$

is in the standard dorm.
