Answer:

Yes, It is a Right Triangle.

Step-by-step explanation:

The hypotenuse is the longest side of the triangle, so for this problem we set the hypotenuse's value to 18.2

From there it doesn't matter which side is which, as both will undergo the same operations.

If the following equation is true, then it is a right triangle.

7²+16.8²= 18.2²

49 + 282.24 = 331.24

The equation is True.

It is a right-angled Triangle.

The position s(t) of a robot moving along a track at time t is given by s(t)=9t^2−90t+4.

Xelga [282]

The total distance traveled by the robot from t=0 to t=9 is 1422 units

Integration is a way in which smaller components are brought together in pieces to form a whole. Integration can be used in finding areas, volumes and so on.

Given that the position s(t) at any time t is given by the function:

s(t)=9t²−90t+4

The total distance traveled by the robot from t=0 to t=9 can be gotten by integrating the position function within the limits 0< t < 9

Therefore:

$Total\ distance = \int\limits^9_0 {s(t) \, dt \\\\Total\ distance = \int\limits^9_0 {(9t^2-90t+4) \, dt\\\\Total\ distance = [3t^3-45t+4t]_0^9\\\\Total\ distance=-1422\ units$

The total distance is 1422 units

52 998 x 67 = (1,000 - 998) x 67

Tresset [83]

Given:

$\to \bold{52,998 \times 67 = (1,000 - 998) \times 67}$

To find:

Proving

Solution:

$\to \bold{52,998 \times 67 = (1,000 - 998) \times 67}$

Solving L.H.S part:

$\to \bold{52,998 \times 67}\\\\\to \bold{3,550,866}\\\\$

Solving R.H.S part:

$\to \bold{(1,000 -998) \times 67}\\\\\to \bold{(2) \times 67}\\\\\to \bold{ 134 }\\\\$

Therefore $\bold{L.H.S \bold{\neq} R.H.S}$

Factor completely x^3 + 1/8

maksim [4K]

Answer:

((2 x + 1) (4 x^2 - 2 x + 1))/8

Step-by-step explanation:

Factor the following:

x^3 + 1/8

Put each term in x^3 + 1/8 over the common denominator 8: x^3 + 1/8 = (8 x^3)/8 + 1/8:

(8 x^3)/8 + 1/8

(8 x^3)/8 + 1/8 = (8 x^3 + 1)/8:

(8 x^3 + 1)/8

8 x^3 + 1 = (2 x)^3 + 1^3:

((2 x)^3 + 1^3)/8

Factor the sum of two cubes. (2 x)^3 + 1^3 = (2 x + 1) ((2 x)^2 - 2 x + 1^2):

((2 x + 1) ((2 x)^2 - 2 x + 1^2))/8

1^2 = 1:

((2 x + 1) ((2 x)^2 - 2 x + 1))/8

Multiply each exponent in 2 x by 2:

((2 x + 1) (2^2 x^2 - 2 x + 1))/8

2^2 = 4:

Answer: ((2 x + 1) (4 x^2 - 2 x + 1))/8

What is the absolute value of -250?

Andrei [34K]

Answer:

250

Step-by-step explanation:

Pretty much every time it asks for the abasloute value it just asks how much to get the zero on the number line. It will ALWAYS be positive. For example -5 will be 5 to get to zero on the numberline. Same thing with a positive 5.
