Solve ln (3x + 7) = 1. Round to the nearest thousandth.

Answer:

(a) √25 rational

(b) √30 irrational

Step-by-step explanation:

Note : only perfect squares have rational roots

25 = 5² then 25 is a perfect square

            therefore √25 = 5 is a rational number

30 cannot be written in the form a² where ‘a’ I start a natural number then 30 is not a perfect square

           Therefore √30 is irrational.

Answer:

2 , 3 , 5 , 5

Step-by-step explanation:

Prime numbers are numbers that are only divisible by itself and 1.

Divide 150 by primes:

150/2 = 75

75/3 = 25

25/5 = 5

Your prime factorization will be: 2 , 3 , 5 , 5.

Check:

2 * 3 * 5 * 5

= 6 * 25

= 150

Answer:

$11.13

Step-by-step explanation:

24 cans = $38.16

divide both sides by 24 to find the cost per can, as this leaves us with 1 can on one side

24 cans / 24 = $38.16 / 24

1 can = $1.59

multiply both sides by 7 to get 7 cans of soup on one side, which is what we want

1 can * 7 = $1.59 * 7

7 cans = $11.13

Answer:

E. 40

Step-by-step explanation:

First, we can start out by stating that this is a right triangle, since it has a right angle, shown by the marker square in the corner of the triangle. The x part, is called the hypotenuse. When finding the value of the hypotenuse, we use a thing called the Pythagorean Theorem. This theorem is :

a^2 + b^2 = c^2

a is one side length, and b is the other. c is the hypotenuse. To find x, the hypotenuse, we simply plug in the values, and solve.

24^2+32^2 = c^2

576 + 1024 = c^2

1600 = c^2

40 = c

The answer is E. 40.

The probability of selecting a turkey sandwich and a bag of pretzels is 3/8.

Probability determines the likelihood that an event would happen. The odds the event occurs is 1 and the odds that the event does not occur is 0.

The probability of selecting a turkey sandwich and a bag of pretzels = number of turkey sandwiches / total number of sandwiches x number of pretziel bags / total number of bags

12/20 x 10/16 = 3/8

Answer:

( -4 , 3 )

Step-by-step explanation:

Knowing that "y" is the line going up and down and "x' is the line going left to right.

Quadrant | = ( + , + )

Quadrant || =  ( - , +)

Quadrant ||| = (- , - )

Quadrant |v = ( + , - )

Refer to image below if needed.

Hence, from the given we can conclude the following:

Quadrant || =  ( - , +)

( x , y )

x = -4

y = 3

Thus, we have:

( -4 , 3 )

Therefore, the correct answer is ( -4 , 3 )

A function assigns the values. The value of (r+s)(-2) is equal to 9.

A function assigns the value of each element of one set to the other specific element of another set.

Given the function r(x)=3x+5, while s(x)=4x, therefore, the expressions can be written as,

(r-s)(x) =r(x)-s(x) = 3x+5 - 4x = -x+5

(r*s)(x) = r(x)·s(x) = (3x+5)·(4x) = 12x² + 20x

The expression for (r+s)(x) can be written as,

(r+s)(x) = r(x)+s(x) = 3x+5+4x = 7x+5

(r+s)(-2) = 7(-2)+5 = -14+5 = 9

Hence, the value of (r+s)(-2) is equal to 9.

Answer:

87 degrees

Step-by-step explanation:

The triangle with the angles 79 and 15, we can find the last value because all angles in a triangle add up to 180. So, 180-79-15= 86 degrees for the angle of the triangle.

Because the 86 degree angle is complimentary, or when added up to the adjacent angle, is 90 degrees (we see that little box sign), that means that 90-86=4 degrees for the upper triangle in the angle that isn't the question mark. Now that we know 2 values for the top triangle, we can solve for the third value by subtracting those two from 180.

180-89-4=87 degrees. Hope this helps!

Step-by-step explanation:

If the given function is f(x)=x², the value of g(x) will be (3x)².

Each value in the domain is connected to exactly one value in the range according to the function, which is described as a specific form of relationship. They have a predetermined range and domain.

It is given that the coordinate values on the graph g (x) are (1, 9).

Now, For the given function,

g (x) = (3x)²

At point (1, 9)

g (1) = (3(1))²

g(1) = 3²

g( 1) = 9

Since, g(x) = (3x)² satisfies the given coordinate values it will be the obtained result.

Thus, the obtained function will be g(x)= (3x)².

i got 100. not sure how the other guy got 81, but what i did is compare it to a test score or a discount. if you have a total of 100 possible points on the test with every question worth 10 points and i got 9 questions right, i got a 90 percent.

let's say a shopping discount. If you got a 90% discount for a item with original price of $100, it costs $10 with "90" being the amount you took off

if 100 isn't right, i honestly have no clue lol. good luck though
