a right triangle has legs of lengths 6 and 2, what is the length of the hypotenuse to the nearest tenth

PolarNik [594]

Answer:

6.3

Step-by-step explanation:

$6^{2} + 2^{2} = x^{2}$

40 = $x^{2}$

$\sqrt{40} = \sqrt{x^{2} }$

x = 6.3

Find the area bounded by the curve y = x 1/2 + 2, the x-axis, and the lines x = 1 and x = 4 A. 16 B. 10 2/3 C. 7 1/2 D. 28 1/2

To find the area of the curve subject to these constraints, we must take the integral of y = x ^ (1/2) + 2 from x=1 to x=4
Take the antiderivative: Remember that this what the original function would be if our derivative was x^(1/2) + 2
antiderivative (x ^(1/2) + 2) = (2/3) x^(3/2) + 2x
* To check that this is correct, take the derivative of our anti-derivative and make sure it equals x^(1/2) + 2

To find integral from 1 to 4:
Find anti-derivative at x=4, and subtract from the anti-derivative at x=1
2/3 * 4 ^ (3/2) + 2(4) - (2/3) *1 - 2*1
2/3 (8) + 8 - 2/3 - 2 Collect like terms
2/3 (7) + 6 Express 6 in terms of 2/3
2/3 (7) + 2/3 (9)
2/3 (16) = 32/3 = 10 2/3 Answer is B

Is -2.9 a rational or integer or whole or natural number

Burka [1]

Answer:

Step-by-step explanation:

It might help to get artsy/crafty with this. I made it out of construction paper, but I'm going to tell you how to draw it.

Draw a large circle, over have the page. Every number, ever, even the numbers in the smaller circles, go into this circle, fractions, decimals, negatives, zero, whole numbers, every number. Negative infinity to positive infinity and everything in between. These are rational numbers.

Now draw a smaller circle inside that one. In the smaller circle there are positive and negative numbers, but no fractions. Every number in this circle is also in the larger circle, but not every number in the bigger circle in in this smaller one. Negative infinity to positive infinity, no fractions. These are integers.

Draw a smaller circle inside the smaller one. No negative numbers in this one, only positive numbers and zero. 0 to infinity, no fractions. These are whole numbers.

One more circle inside the smallest one. Only positive whole numbers in here. No zero. 1 to infinity, no fractions. These are natural numbers.

-2.9 is negative and decimal, so not a natural, not a whole, not an integer. That leaves rational.

PLEASE I NEED HELP WITH THIS

Masteriza [31]

Answer: $m\angle 2+m\angle 5=180^{\circ}$

Step-by-step explanation:

You are ending by proving $\angle 2$ and $\angle 5$ are supplementary, so right before that, you need to prove their measures add to 180 degrees.
