Answer:

The answer is 804.25

Step-by-step explanation:

\frac{32}{2}=16

Area = 3.14 * 16^2

A=3.141592654×16×16

804.2477193mm^2

Area 804.248

Answer:

803.84 bc radius is half of diameter which is 16

Area of circle is (pi)r^2 = (3.14)16^2= 3.14 x 256 = 803.84

For what values of x does 25 Superscript x Baseline = 5 Superscript x squared minus 3?
umka2103 [35]

For this case we have the following equation:

25^{x} = 5^{ x^2-3}

Rewriting we have:

5^{2 (x)} = 5^{ x^ 2-3}\\5^{ 2x} = 5^{ x^ 2-3}

For expressions to be equal, exponents must be equal. So:

2x = x ^ 2-3\\x ^ 2-2x-3 = 0

To factor, we look for two numbers that, when multiplied, result in -3 and when added, result in -2. These numbers are -3 and 1.

(x-3) (x + 1) = 0

Thus, the roots are:

x_ {1} = 3\\x_ {2} = - 1

Answer:

x_ {1} = 3\\x_ {2} = - 1

Find the value of x and y<br><br><br>Please help me. Thank you​
STatiana [176]

Answer:

Step-by-step explanation:

let each angle=A

A+A+A=180

3A=180

A=180/3=60°

as the angles are equal so sides are equal.

16+y=46

y=46-16=30

applying sine formula

\frac{30}{sin z} =\frac{46}{sin~80} \\sin~z=\frac{30}{46} \times ~sin~80=\frac{15}{23} \times sin ~80\\z=sin^{-1}( \frac{15}{23} \times sin ~80) \approx~39.96^\circ \approx40^\circ

z+x=60

40+x=60

x=60-40=20°

The domain of a function is?
Grace [21]
The correct answer is B) The set of all first elements of the function. Let's say you had these three points on a graph of a function: (0.9), (2.6), (4,7). The domain of these three points would be (0,2,4). The domain is just the input for which the function is defined. Hope this helps.
