Tresset [83]2 years ago
8 0

Answer:

No, 9^2 +7^2 \neq 12^2

Step-by-step explanation:

9^2 +7^2 = 81+ 49 =130...(1)

12^2 = 144...(2)

From equations (1) & (2) it is obvious that:

9^2 +7^2 \neq 12^2

Thus, the given is not a right triangle.

The following graph shows the cost c, in dollars, of p pounds of strawberries at a local grocery store.
lorasvet [3.4K]

Answer:

A. The ordered pair (5, 3.5) represents 5 lbs. of strawberries cost $3.50.

B. The cost per pound of strawberries is shown at (1, 0.7).

C. The relationship shown in the graph is a direct variation because as the pounds of strawberries increase, the cost also increases.

Explanation:

A. The coordinate is in (x,y). The x-axis represents the pound of strawberries and the y-axis represents the cost of the strawberries.

B. The cost for one pound of strawberries can be calculated to find the exact value of y (cost) when x is 1. The graph shows 5 lbs. of strawberries cost $3.50 so divide $3.50 by 5 lbs. to find the cost per pound of strawberries. 3.5 ÷ 5 = 0.7. On the graph, the cost for one pound of strawberries is at (1, 0.7)

C. A direct variation in a graph is shown when both x and y increase or decrease together. In this case, as the pounds of strawberries increase, the cost of the strawberries also increases.

ASAP Which power can you write to represent the volume of the cube shown? Enter the power as an expression with a base and an ex
n200080 [17]

Answer:

The power for the volume of the cube is '3'.

Exponent form of the volume is

Volume of the cube is  inch³.

Step-by-step explanation:

We are given,

A cube with side equal to  inches.

As we know,

Volume of a cube =

Thus, we get,

Volume of the given cube is,

Volume =

i.e. Volume =  inch³

Thus, we have,

The power for the volume of the cube is '3'.

Exponent form of the volume is

Volume of the cube is  inch³.

Write answer in slope intercept form (3,-8); slope= -3
Slav-nsk [51]

Answer:

y=-3x-8

Step-by-step explanation:

The slope intercept form is y=mx+b.

The "mx" is the slope; which in this case is -3. So -3x.

The "b" is the y-intercept, which is this case is the -8 because it is the 2nd number in the coordinate point.

This is why the answer is y=-3x-8.

Find the lateral and total surface area for the cone. If necessary, round to the nearest tenth and leave the
bija089 [108]

9514 1404 393

Answer:

  • 262.2π cm²
  • 392.16π cm²

Step-by-step explanation:

The lateral surface area is the product of half the circumference, and the slant height:

  LA = πrh = π(11.4 cm)(23 cm) = 262.2π cm²

The total surface area adds the area of the base to that:

  A = πr² +LA = π(11.4 cm)² +262.2π cm² = (129.96 +262.2)π cm²

  A = 392.16π cm²
