Answer:

[tex]2 \times 3.14 \times radius[/tex]

B

Answer:

The process he should use in order to find the circumference of a circle is that he should find the radius and multiply the radius by 2 and then afterwards multiply the product by pi or 3.14. This is because the circumference of a circle is formulated as C = 2πr or C = 2(3.14)r.

Answer:

The inequality would be 4x + 9 ≥ 0

Step-by-step explanation:

You could use this inequality to solve the domain as any number can be put into this equation as long as it doesn't make what is under the square root symbol (4x + 9) negative. Therefore, you can build this inequality and solve from there if you would like.

For this case we have a function of the form [tex]y = f (x)[/tex], where:

[tex]f (x) = \sqrt {4x + 9} +2[/tex]

We must look for the domain of the function. By definition, the domain of a function is given by all the values for which the function is defined.

So, for the given function to be defined, the argument of the root must be positive, that is:

[tex]4x + 9\geq 0[/tex]

Answer:

6x-2

Step-by-step explanation:

[tex]- 4x(1-3)-(2x+2)[/tex]

When x=5 the value of the expression is 28

Now we check with each expression given in the options

Plug in 5 for x in each option

[tex]-6x-1=-6(5)-1=-30-1= -31[/tex]

[tex]-6x+2=-6(5)+2=-30+2= -28[/tex]

[tex]6x+1=6(5)+1=30+1= 31[/tex]

[tex]6x-2=6(5)-2=30-2=28[/tex]

So 6x-2 gives us 28 when x=5

Answer:

the desired result is (p + q) = (3 + 5) = 8

Step-by-step explanation:

Let's solve this system of linear equations in the usual way:  find the values of p and q.  Then find (p + q) as a numerical result.

Solve:

2p+q=11

p+2q=13

Multiply the second equation by -2:

2p + q = 11

-2p - 4q = -26

Combining these two equations results in -3q = -15, and so q must be 5.

Subbing 5 for q in the first equation, we get:

2p + 5 = 11, or 2p = 6.  Then p = 3.

Then the desired result is (p + q) = (3 + 5) = 8

The required answer is  p + q is equal to 8 by  solving systems of equations 2p+q=11 and p+2q=13. The required sum is 8.

To find the value of p + q, we can use the given system of equations:

Equation 1: 2p + q = 11

Equation 2: p + 2q = 13

We can solve this system of equations by either the substitution method or the elimination method. Let's use the elimination method:

Multiply Equation 1 by 2:

2(2p + q) = 2(11)

4p + 2q = 22 ...(Equation 3)

Subtract Equation 2 from Equation 3:

(4p + 2q) - (p + 2q) = 22 - 13

4p + 2q - p - 2q = 9

3p = 9

Divide both sides by 3 to solve for p:

p = 9 / 3

p = 3

Now substitute the value of p back into Equation 1:

2(3) + q = 11

6 + q = 11

Subtract 6 from both sides to solve for q:

q = 11 - 6

q = 5

Finally, we can find p + q:

p + q = 3 + 5

p + q = 8

Therefore, p + q is equal to 8 solving systems of equations 2p+q=11 and p+2q=13. The required sum is 8.

Answer:

7.1 inches

Step-by-step explanation:

An Isosceles right triangle is one with two sides equal and the angles equal too.The angles in this case are 45°

For this question, to get the hypotenuse, you apply the Pythagorean relationship where the legs will be represented by a and b where as the hypotenuse will be represented by c.

[tex]a^2+b^2=c^2\\[/tex]

Given;

One leg = 5 inches, but you know that in this triangle, the two sides are equal, hence the other side/leg is 5 inches.

Lets take one side of the triangle as a=5 inches

The other side as b=5 inches

The hypotenuse as c=?

Apply the expression;

[tex]a^2+b^2=c^2\\\\5^2+5^2=c^2\\\\25+25=c^2\\\\50=c^2\\\\c=\sqrt{50} =7.071[/tex]

Answer:

x²+y²=16

Step-by-step explanation:

the general equation for a circle is given as :

(x−h)²+(y−k)²=r²

where (h, k) is the coordinate of the center of the circle and r is the radius

in this case h=0, k=0 and r = 4

equation becomes

x²+y²=4²

or

x²+y²=16

Answer: Last option.

Step-by-step explanation:

The equation of a circle in Center-radius form is:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

Where the center is at the point (h,k) and "r" is the radius.

If the center of this circle is at the origin, means that:

[tex]h=0\\k=0[/tex]

Since the radius is 4, then:

[tex]r=4[/tex]

Now we need to substitute these values into the equation of the circle.

[tex](x-0)^2+(y-0)^2=(4)^2[/tex]

Simplifying the equation, we get:

[tex]x^2+y^2=16[/tex]

This matches with the last option.

Answer:

To test whether or not a number is divisible by 4 is to check to see if the number that’s made from the final two digits of the original number is itself divisible by 4. If it is, then the entire number is divisible by 4 too.

The correct answer is (5,-2).

Answer:

D

Step-by-step explanation:

Answer:

Step-by-step explanation:

(1) y = 4x + 5 and (2) y = 4x - 5

substitute (1) to (2):

4x + 5 = 4x - 5         subtract 4x from both sides

5 = -5      FALSE (no solution)

(1) y = 4x + 5 and (2) 2y = 8x + 10

substitute (1) to (2):

2(4x + 5) = 8x + 10          divide both sides by 2

4x + 5 = 4x + 5         subtract 4x from both sides

5 = 5   TRUE (infinitely many solutions)

(1) y = 4x + 5 and (2) y = x + 5

substitute (1) to (2):

4x + 5 = x + 5         subtract 5 from both sides

4x = x          subtract x from both sides

3x = 0         divide both sides by 3

x = 0

Put it to (2):

y = 0 + 5 = 5

One solution (0, 5)

(1) y = 4x + 5 and (2) y = 8x + 10

substitute (1) to (2):

4x + 5 = 8x + 10       subtract 5 from both sides

4x = 8x + 5       subtract 8x from both sides

-4x = 5           divide both sides by (-4)

x = -1.25

Put it to (1):

y = 4(-1.25) + 5 = -5 + 5 = 0

One solution (-1.25, 0)

[tex]\frac{540}{x} =\frac{92}{100}[/tex]

Cross multiply...

92x = 540 * 100

92x = 54000

Isolate x by dividing 92 to both sides...

92x/92 = 54000/92

The answers are:

[tex]AbsoluteError=20mhz[/tex]

[tex]RelativeError=2.5(Percent)[/tex]

To solve the problem we need to remember that the absolute error is the difference between the expected value and the measured value, also, to calculate the relative error we first need to calculate the absolute error, and then, divide it by the expected measure.

So, calculating we have:

[tex]AbsoluteError=Expected-MeasuredValue\\\\AbsoluteError=800mhz-820mhz=-20mhz[/tex]

We can see that we obtained a negative value, however, when we are working with "absolute" values, the negative symbol is discarded, so, we have that:

[tex]AbsoluteError=20mhz[/tex]

Now, to calculate the relative error, we need to use the following formula:

[tex]RelativeError=\frac{AbsoluteError}{ExpectedValue}*100\\\\RelativeError=\frac{20}{800}*100=0.025*100=2.5(Percent)[/tex]

So, we have that the relative error is equal to 2.5%.

Hence, we have that:

[tex]AbsoluteError=20mhz[/tex]

[tex]RelativeError=2.5(Percent)[/tex]

Have a nice day!

Absolute error is 20 MHz and relative error is 2.5%.

Absolute error: Absolute error is the difference between the measured value and the actual value. In this case, the absolute error is 820 MHz - 800 MHz = 20 MHz.

Relative error: Relative error is the ratio of the absolute error to the actual value. The relative error can be calculated as (820 MHz - 800 MHz) / 800 MHz = 0.025 or 2.5%.

Step-by-step explanation:

Slope = (-2 - 0)/(4 - 0) = -1/2, b = 0

So

y = -1/2 x

Answer:

C

Step-by-step explanation:

By observation, we can see that the slope of the graph is negative (i.e the graph goes from top left to bottom right) hence the number attached to the x-term must be negative. We can see that E and F have positive x-terms, hence these cannot be correct.

Now we are left with A, B, C, D as possible choices.

you are given that point (4, -2) is on the line, hence when x = 4, y must = -2.

Use this knowledge to test each of A, B, C, D to see which one gives y = -2 when we try x = 4

When x = 4

A) -[tex]\frac{1}{4}[/tex] (4) = -1 ≠ -2 (wrong)

B) -2 (4) = -8 ≠ -2 (wrong)

C) -[tex]\frac{1}{2}[/tex](4) = -2 (correct)

D) -4(4) = -16 ≠ -2 (wrong)

Answer:   [tex]\bold{\dfrac{1}{19}}[/tex]

Step-by-step explanation:

Let x represent the quantity of yellow cubes

Yellow: x

Blue: three times yellow --> 3x

Green: five times blue --> 5(3x) = 15x

Yellow + Blue + Green = Total cubes

    x      +   3x  +    15x   =       19x

[tex]Probability=\dfrac{yellow}{total}=\dfrac{x}{19x}=\large\boxed{\dfrac{1}{19}}[/tex]

The probability of Sarah taking out a yellow cube from the bag is 0.7 or 5/7.

The fraction of favorable outcomes of an event to the total number of outcomes of the event is said to be the probability. The fraction can also be written in the simplest form.

P(E)= n(E)/n(S) where E -event, n(E) - favorable outcomes and n(S) is the total outcomes.

It is given that a bag contains blue cubes, yellow cubes, and green cubes.

Consider the number of blue cubes = n

So, the number of yellow cubes = 3 times as many as blue cubes

                                                     = 3n

Then, 5 times as many as green cubes = blue cubes

⇒ number of green cubes = n/5

Then the total number of cubes in the bag

= n + 3n + n/5

⇒ [5n + 15n + n]/5

⇒ 21n/5

Then the probability of taking out a yellow cube = (possible outcomes of a yellow cube)/(total number of cubes)

⇒ [tex]\frac{(3n)}{(21n/5)}[/tex]

⇒ 15n/21n

⇒ 5/7

∴ The probability of taking out a yellow cube = 5/7 = 0.7.
