So for this, you will be dividing 9.3/3.1 and 10^34/10^17 separately.

Starting with 9.3/3.1, that equals 3

Now with 10^34/10^17, remember that the rule with dividing exponents with the same base is that you are just subtracting the exponents. In this case: 10^(34 - 17) = 10^17

Now we put the two quantities together, and your answer will be 3 x 10^17, or the second option.

The length of x is option 1. 24.8.

Step-by-step explanation:

Step 1:

We determine the value of the base for the right triangle first.

According to the Pythagorean theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

Assume the base of the right triangle is y.

The hypotenuse measures 18 units while the other sides are 13 units and y units.

Step 2:

According to the Pythagorean theorem,

$18^{2} = y^{2} + 13^{2} , y^{2} = 18^{2} - 13^{2} .$

$y^{2} = 155, y = 12.44.$

So y equals 12.44 units but as y is only the base length for one of the triangles,

$x = 2y = 2 (12.44) = 24.88.$

Rounding off 24.88 we get 24.9 which is closest to 24.8.So the length of x is option 1. 24.8.

Work out the sizes of each unknown exterior angle in this polygon

goldenfox [79]

Answer:

see explanation

Step-by-step explanation:

The sum of the exterior angles of a polygon = 360°

The exterior angle to interior angle is

exterior angle = 180° - 110° = 70°

Sum the exterior angles and equate to 360

x + 2x + 70 + 2x - 50 + x + 40 = 360 , that is

6x + 60 = 360 ( subtract 60 from both sides )

6x = 300 ( divide both sides by 6 )

x = 50

Then measure of exterior angles is

x = 50°

2x = 2 × 50 = 100°

x + 40 = 50 + 40 = 90°

2x - 50 = 2(50) - 50 = 100 - 50 = 50°

For the following exercises, evaluate the function at the indicated values:

STALIN [3.7K]

Answer:

The evaluated function for the indicated values is given below.

The value of f(-3) is 20 .

The value of f(2) is 10 .

The value of f(-a) is $2|-3 a-1|$ .

The value of -f(a) is $-2|3 a-1|$ .

The value of f(a+h) is $2|3 a+3 h-1|$ .

Step-by-step explanation:

A function $f(x)=2|3 x-1|$ is given.

It is required to evaluate the function at $f(-3) ; f(2) ; f(-a) ;-f(a) ; f(a+h)$ .

To evaluate the function, substitute the indicated values in the given function to determine the output values and simplify the expression.

Step 1 of 5

The given function is $f(x)=2|3 x-1|$ .

To evaluate the function at f(-3), substitute -3 in the given function $f(x)=2|3 x-1|$\\ $f(-3)=2|3(-3)-1|$\\ $f(-3)=2|-9-1|$\\ $f(-3)=2|-10|$\\ $f(-3)=2(10)$\\ $f(-3)=20$$
