Answer:

Radius AC=12

Step-by-step explanation:

AB is a tangent to circle c so the tangent AB is perpendicular to the radius at A.

Then triangle ABC is right triangle at A.

So by Pythagoras theorem,

CB^2=AB^2 + AC^2

37^2= 35^2 + AC ^2

1369=1225 + AC^2

AC^2= 1369-1225= 144

AC=radical AC^2 =radical 144=12

Hope this helps...

(Note: ^ means power)

Answer:

AC = 12

Step-by-step explanation:

We can use the Pythagorean theorem

a^2 + b^2 = c^2

AC ^2 + AB ^2 = CB^2

AC ^2 +35^2 = 37^2

AC ^2 +1225=1369

Subtract 1225

AC^2 = 1369-1225

AC ^2 =144

Take the square root of each side

AC = sqrt(144)

AC = 12

Mal starts with 350 dollar

Each week she adds $30.

W is number of weeks Mal adds money.

S is total amount of money in her account.

=> S =30W + 350

After W = 19 weeks, Mal will have 30 x 19 + 350 = 920 dollar

[tex]\frac{1}{3}[/tex] chance.

Step-by-step explanation:

The only factors of 6 on a die is 1, 2, 3, and 6

The chance of getting 4 or 5 (not factors of 6) is [tex]\frac{2}{6} =\frac{1}{3}[/tex] chance.

(None of the options you gave is correct)

The probability of getting numbers which is not a factor of 6.

                          [tex]P(E)=\frac{2}{6}=\frac{1}{3}[/tex]

To understand more, check below explanation.

The numbers on die which is factors of 6 is,

                               1,2,3,6

So that, numbers on die which is not factor of 6 is, 4 and 5.

We have to find probability that  the score is not a factor of 6.

Total number of favorable outcomes = 2

Total outcomes = 6

Probability that  the score is not a factor of 6,

                          [tex]P(E)=\frac{2}{6}=\frac{1}{3}[/tex]

Slope-Intercept Form y = mx + b

Y = 5

Slope = -2/1

Step-by-step explanation:

Slope-Intercept Form y = mx + b

m = Slope; Rise over Run; Remember there is always an understood 1 in the denominator. If the slope is positive it goes up and to the right and if the slope is negative it goes down and to the right.

b = Y-intercept; This is where the line crosses the y-axis at. If it's positive it's above the x-axis and if negative below.

Step-by-step explanation:

Fifteen of the 100 digital video recorders​ (DVRs) in an inventory are known to be defective, the total number of non-defective DVRs will be 100-15 = 85 DVRs.

If 85 DVRs are not defective, the probability that you randomly select a DVR that is not​ defective can be expressed as:

P(non-defective DVRs) = Total number of non-defective DVRs /Total DVRs

P(non-defective DVRs) = 85/100

P(non-defective DVRs) = 17/20

Answer:

0.85

Step-by-step explanation:

Given;

Number of defective DVRs D = 15

Total number of DVRs T = 100

Number of non defective DVR N = T - D = 100 - 15 = 85

The probability of selecting a non defective DVR P(N) is equal to the number of non defective DVR divided by the total number of DVRs.

P(N) = N/T

Substituting the values;

P(N) = 85/100

P(N) = 17/20 = 0.85

Answer:

C. Slope and [tex]10.49 g/cm^3[/tex]

Step-by-step explanation:

We're missing the graph itself, but I can make an educated guess:

- Assuming x = volume and y = mass:

[tex]p = \frac{m}{v}[/tex]

density = mass/volume

x = volume = run

y = mass = rise

mass/volume = rise/run = slope

The slope of the line (assuming the graph is purely linear) represents mass/volume, which is the formula for density.

I had to Google the density of silver itself. Do the math from the graph for a more appropriate answer, as the graph may be less scientifically precise.

Answer: [tex]\frac{104}{45}[/tex]

Step-by-step explanation:

[tex]2.31^-[/tex]

Let x be equal to that.

[tex]x=2.31^-[/tex]

Multiply by 1 followed by as many zeros as repeating numbers. In this case it's just one repeating decimal, therefore, 1 followed by 1 zero or 10.

[tex]10x=2.31^-*10[/tex]

This basically moves the decimal point one number to the right.

[tex]10x=23.11^-[/tex]

Subtract the first equation from this new equation.

[tex]10x=23.11^-\\-x=2.31^-[/tex]

--------------------------

The repeating decimal is eliminated and we are left with:

23.1

- 2.3

---------

20.8

We also have 10 - 1 = 9. We are left with:

[tex]9x=20.8[/tex]

Divide by 9.

[tex]x=\frac{20.8}{9}[/tex]

To get rid of the decimal, multiply by 1 followed by as many zeros as decimals. In this case 1.

[tex]x=\frac{20.8}{9} (\frac{10}{10} )[/tex]

[tex]x=\frac{208}{90}[/tex]

Step-by-step explanation:

i know this is very late but ..

area of triangle= b*h/2

24*7/2=84

and it said the parallelogram is 5 times the area so we do

84*5=420 which is the total area of the parallelogram

now to find h we need to do

420/30=14

h=14 because 30*14=420

The required value of h is 14 cm for the given parallelogram.

A parallelogram is defined as a special type of quadrilateral that has both pairs of opposite sides parallel and equal.

The area of the triangle is (247)/2 = 84 square cm.

Since the area of the parallelogram is 5 times the area of the triangle, the area of the parallelogram is 845 = 420 square cm.

The area of the parallelogram is equal to the base (30 cm) multiplied by the height (h cm), so we can set up the equation:

30h = 420

To find the value of h, we can divide both sides of the equation by 30:

h = 420/30

h = 14 cm

Thus, the required value of h is 14 cm.

Answer:

On the right side, she used distributive property

Step-by-step explanation:

Answer:

[tex]\theta = \pm \pi \cdot i[/tex], [tex]\forall i \in \{0,2,4,...\}[/tex]

Step-by-step explanation:

The determination of the maximum can be done with the help of the First and Second Derivative Tests. The first and second derivatives of the function are, respectively:

[tex]r' = -4\cdot \sin \theta[/tex]

[tex]r'' = -4\cdot \cos \theta[/tex]

First Derivative Test

[tex]-4\cdot \sin \theta = 0[/tex]

[tex]\sin \theta = 0[/tex]

Given the periodicity of the function, there are multiple solutions. The set of solutions is represented by:

[tex]\theta = \pm \pi \cdot i[/tex], [tex]\forall i \in \mathbb{N}_{O}[/tex]

Second Derivative Test

There are multiple solutions. If [tex]i[/tex] is an odd number, then cosine is negative and output is positive, which means that associated value is an absolute minimum. Otherwise, if [tex]i[/tex] is zero or an even number, the cosine is positive and output is negative, which means that associated value is an absolute minimum. Consequently, the values of [tex]\theta[/tex] so that [tex]r[/tex] is a maximum are:

[tex]\theta = \pm \pi \cdot i[/tex], [tex]\forall i \in \{0,2,4,...\}[/tex]

The ordered pair that has a rise of -2 and a run of 3, and also lies on the same line as the point (6, 2) is: d) (9,0) and (12, -2)

The rise of the ordered pair, (9,0) and (12, -2):

Rise = change in y =  -2 - 0 = -2.

The run of the ordered pair, (9,0) and (12, -2):

Run = change in x = 12 - 9 = 3.

Answer:

Your graph will have a y intercept of (0,2) and from that point move up 2 and to the right 5 to the point (5,4) then draw a line connecting and extending beyond these two points.

Step-by-step explanation:

y = mx + b

m = slope which is rise over run

b = y intercept

y = 2/5x + 2

m = 2/5

b = 2

This means that your graph will have a y intercept of (0,2) and from that point move up 2 and to the right 5 to the point (5,4) then draw a line connecting and extending beyond these two points.

Answer:

See explanation below

Step-by-step explanation:

A system of linear equations is a system that is formed when you have two or more variables, for example:

[tex]x=2y+z\\3y-4x=7y+2z\\2y+z=4x+3y[/tex]

In this case, we have 3 equations with 3 variables in total (x, y and z). Thus, we would need to solve a system of linear equations (they are linear because none of the variables have exponents).

On the other side, a single linear equation has only one variable that we need to find, for example:

[tex]3x=\frac{5}{3}[/tex]

In this case we would just have to solve for x

[tex]3x=\frac{5}{3} \\9x=5\\x=\frac{5}{9}[/tex]

Thus, we need to solve a system of linear equations when we have more than one variable (and more than one equations) as opposed to when we have just one variable and a single equation (single linear equation)

95% of all newborn babies in the United States weigh between *2500g and 4500g*

99.7% of all newborn babies in the United States weigh between *2,000g and 5,000g*

Step-by-step explanation:

Using the Empirical Rule, it is found that 68% of all newborn babies in the United States weigh between 3,000g and 4,000g.

It states that, for a normally distributed random variable:

In this problem, the mean is of 3,500 g with a standard deviation of 500 g, hence:

3500 - 500 = 3,000 g.

3500 + 500 = 4,000 g.

Hence, 68% of all newborn babies in the United States weigh between 3,000g and 4,000g.
