Answer:

y = -3

Step-by-step explanation:

5(y+2/5) = -13

distributive property ( 5 x y is 5y, 2 divided by 5 is 0.4 x 5 is 2.)

5y + 2 = -13

take away 2 from both sides (2 is currently positive, so doing opposite)

5y + 2 - 2 = -13 - 2

divide by 5 on both sides

5y = -15

y = -3

Answer:

5

Step-by-step explanation:

to find the mean you have to add up all the numbers so

1+8=9

9+3=12

12+2=14

14+8=22

22+8= 30

and then you divide by the amount of numbers which is 30 / 6 = 5

The time it would take for the bacteria to reach 1119 is 5.83 hours

Given the function:

[tex]Pt= P_0e^k^t[/tex]

To find the exponential growth;

80 = [tex]50e^k^*^3[/tex]

[tex]k= 1.6/3\\k= 0.533[/tex]

If there is a constant growth, then to get to 1119:

1119= [tex]50e^0^.^5^3^3^*t[/tex]

3.8 = 0.533*t

t= 5.83 hours

Therefore, it would take 5.83 hours for the bacteria to increase to 1119.

The degrees of freedom in a regression model is 2 if the model that has 10 observations and 7 independent variables.

The amount of rows of training data used to fit the model equals the degrees of freedom.

Total observation = 10

Number of independent variables = 7

Degree of freedom for regression = 10 – 7 - 1

= 2

Thus, the degrees of freedom in a regression model is 2 if the model that has 10 observations and 7 independent variables.

Answer:

The Graph is included Bellow...

Step-by-step explanation:

This function will start at (0,2) and proceed to the right (based on its family function of √x) and since it has been shifted up 2 from f(x) then we will move two units up.

The domain can be considered the range from right to left that the function is restricted in. In this case, it starts at -2 (Which the function doesn't reach) and will stop at 7.

So the Graph you are looking for will start at (0, 2) and proceed to the right until (7, 4.6) ish. I have included a table to help your graph it!

The curve is an ellipse having (-1,4) as center and half-axis (2 and 6)

Answer:

3(x + 4)(x - 5) = 3x² - 3x - 60.

Step-by-step explanation:

3(x + 4)(x - 5)

Combine x + 4 and x - 5 using FOIL, or first, outer, inner, last.

F: x * x = x²

O: x * -5 = -5x

I: x * 4 = 4x

L: 4 * -5 = -20

3(x² - 5x + 4x - 20)
Simplify inside the parenthesis.

3(x² - x - 20)

Distribute the 3 into the equation.

3x² - 3x - 60

The option that is the functions is graphed below is known as option A = Y= (x+4) -2.

The function graphed above is Y=|x+4|-2 because  when you solve for the graphs,  the number in the x-axis is always changed or turned to  the other side and there one can see that it would be -4 would be +4, and +4 and also -4.

Note that

Y = (x+4) -2.

x = (0 + 4) - 2

x = 4-2

x =2

Therefore, plug x into the equation.

Y = (x+4) -2.

= ( 2 + 4) - 2

= (6) -2

= 4

Therefore, The option that is the functions is graphed below is known as option A = Y= (x+4) -2.

"Segment MP is a diameter of circle O. Circle O is shown. Line segment M P is a diameter. Line segment N O is a radius. Angle N O P is 150 degrees.

Which equation can be used to find mArc M N?

mArc M N + 150 = 180, mArc M N + 150 = 360, mArc M N – 150 = 180, mArc M N – 150 = 360"

The Equation m Arc(MN) + 150  = 180 is used to find mArc MN. Thus, the correct option is A.

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

It is Given:

Segment MP is the diameter of circle O. Circle O is shown.

Line segment M P is a diameter.

Line segment N O is a radius.

∠NOP = 150°

We need to Find the Equation for m Arc MN

We already know the Diameter subtends 180° as it is the half of Circle 360°

∠NOP = 150°  

∴ m(Arc NP) = 150°

The measure of an arc is the measure of its central angle

Therefore,

m Arc Diameter = 180°

m Arc(MN) + m Arc(NP)  = 180

m Arc(MN) + 150  = 180

Therefore, the Equation m Arc(MN) + 150  = 180 is used to find mArc MN.

Thus, the correct option is A.

Answer:

AC = BC = 5

AB = 5√2

∠A = ∠B = 45

∠A = 90

Step-by-step explanation:

AC = 5 ( Reason : 5 squares are present in between A and C )

Similarly,

BC = 5

By Pythagoras theorem,

(AB)² = (AC)² + (BC)²

        = 5² + 5²

        = 2 * 5²

(AB)² = 2 * 5²

AB = 5√2

Since, sides AC and BC are equal,

∠A = ∠B = 45

Since, AC is perpendicular to BC,

∠A = 90

Answer:  -∞ < x < ∞

Step-by-step explanation:

      The domain is all the x-values, or inputs, of a function. The range is the y-values, or outputs, of a function.

       In this case, we are looking for the x-values of the function. Since the function will keep going "out forever" in both directions, the answer should be the fourth option;

             - ∞ < x < ∞

The first step that we must take to solving this problem is to fully understand what the problem statement is asking from us and what is given us to solve the problem.  Looking at the problem statement, we can see that they are asking us to determine what the domain of the function is in the graph that was provided.  However, first of all, let us define what domain is.

Looking back at our problem, we can see that this is similar to the example that was provided in the definition.  We can see that the parabola reaches out to both positive and negative infinity in the x-direction but at a slope. Although we can only see it reach -2 and 6 we know that the parabola continues going on even after that.  

Therefore, looking at the options that were provided option D, -∞ < x < ∞ would be the best fit as it showcases that x reaches from negative infinity to positive infinity.

The zeroes of the given polynomial is 1 and -6.

A polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables.

Here, given equation;

          f(x) = (x - 1)(x + 6)

for finding the zeros of the equation we need to put.....f(x) = 0

           0 = (x - 1)(x + 6)

     x - 1 = 0      or       x + 6 = 0

     x = 1          or    x = -6

Thus, The zeroes of the given polynomial is 1 and -6.
