9. The sum of 10 and 7 times a number is 59. What is the
number? (Use n as the variable.)

Answers

10+7n=59
7n=59-10
7n=49
n=49/7
n=7

Answer:

7

Step-by-step explanation:

Let,

The number be = n

According to the question,

First 7 times of n = 7n

Sum of 10 and the number = 7n + 10

Said that,

The sum of 10 and 7 times of the number is 59.

Therefore,

By the problem ,

=> 7n + 10 = 59

=> 7n = 59 - 10

=> 7n = 49

[tex] = > n = \frac{49}{7} [/tex]

=> n = 7

Hence,

The required number is 7 (Ans)

Complete the equation of this circle :

Answers

Answer:

-2 , 4 , 36

Step-by-step explanation:

[tex](x - -2)^{2} + (y - 4)^{2}[/tex]

[tex](x + 2)^{2} + (y - 4)^{2} =36[/tex]

The equation of the circle with a radius of 6 and center (-3, 4) is (x + 3)² + (y - 4)² = 36.

The equation of a circle with radius r and center (h, k) is given by:

(x - h)² + (y - k)² = r²

Radius (r) = 6

Center (h, k) = (-3, 4)

Plugging these values into the equation, we have:

(x - (-3))² + (y - 4)² = 6²

(x + 3)² + (y - 4)² = 36

Therefore, the equation of the circle with a radius of 6 and center (-3, 4) is (x + 3)² + (y - 4)² = 36.

Fill in values for the table using the function

Answers

Answer/Step-by-step explanation:

Given:

f(x) = -3x + 4

✔️First row, find x when f(x) = 4:

Substitute f(x) = 4 into the equation

4 = -3x + 4

4 - 4 = -3x

0 = -3x

Divide both sides by -3

0/-3 = x

x = 0

✔️ Second row, find f(x) when x = -1:

Substitute x = -1 into the equation

f(-1) = -3(-1) + 4

f(-1) = 3 + 4

f(-1) = 7

✔️ Third row, find f(x) when x = 1:

Substitute x = 1 into the equation

f(1) = -3(1) + 4

f(1) = -3 + 4

f(1) = 1

✔️ Fourth row, find x when f(x) = 9:

Substitute f(x) = 9 into the equation

9 = -3x + 4

9 - 4 = -3x

5 = -3x

Divide both sides by -3

5/-3 = x

x = -⁵/3

A baby fish was 1.5 centimeters in length when it first hatched . The fish grew at a rate of 0.25 centimeter per week.
Which graph best shows this relationship between the length of the fish in centimeters , y, and the time in weeks, x?

Answers

If you think about I would suggest B only because it makes more sense but I might be wrong..

Hope this helped a little!

The solution is Option A.

The equation of line is y = 0.25x + 1.5 , where the slope m = 0.25

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

The initial length of the baby fish is b = 1.5 cm

The baby fish grew at a rate of 0.25 centimeter per week

So , the slope of the line m = 0.25 cm

And , equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

Substituting the values in the equation , we get

y = 0.25x + 1.5   be equation (1)

Hence , the equation of line is y = 0.25x + 1.5

Given

[tex]g(x) = 10\sqrt{x - 2[/tex]

Required

Determine the inverse function

[tex]g(x) = 10\sqrt{x - 2[/tex]

Replace g(x) with y

Swap the positions of x and y

[tex]x = 10\sqrt{y -2[/tex]

Divide through by 10

[tex]\frac{x}{10} = \sqrt{y - 2[/tex]

Square of both sides

[tex]\frac{x^2}{100} = y - 2[/tex]

Make y the subject

A 12 foot ladder leans against a building. The angle of elevation from the ground to the foot of the ladder is 46°. Find, to the nearest tenth of a foot, how far is the foot of the ladder from the building

Answers

Answer:

8.3 ft

Step-by-step explanation:

Hypotenuse is the longest side

Opposite is the side opposite the angle

Adjacent is the remaining side

Draw the triangle out, and you'll find that the hypotenuse (length of ladder) is 12ft, and that you are looking for the adjacent side (length of the foot of the ladder to the building). Rule out the opposite side (side of building) as it is not needed. The appropriate trigonometric formula is then the [tex]cos(angle) = \frac{adjacent}{hypotenuse}[/tex], rearranged to find the adjacent side is [tex]adjacent = cos(angle)*hypotenuse[/tex]  

substitute the values in and you get cos(46) x 12 = 8.335900446

To determine the molecular masses of the proteins, a standard curve is created plotting the known molecular masses of the proteins in the Precision Plus Protein Kaleidoscope prestained standards against the distance they have migrated down the gel from the base of the well.
