The length of the third leg is

STEP-BY-STEP EXPLANATION:

The figure given is a right-angled triangle.

To find the third length of the triangle, we need to apply Pythagora's theorem

It states that

[tex]\begin{gathered} (Hypotenuse)^2=(opposite)^2+(adjacent)^2 \\ \end{gathered}[/tex]

The third length of the triangle is the hypotenuse because it is the longest

[tex]\begin{gathered} (Hypotenuse)^2=4^2+2^2 \\ (Hypotenuse)^2\text{ = 16 + 4} \\ (Hypotenuse)^2\text{ = 20} \\ \text{ Take the squareroots of both sides} \\ \text{ }\sqrt[]{(Hypotenuse)^2\text{ }}\text{ = }\sqrt[]{20} \\ \text{Hypotenuse = }4.472 \\ \text{Hypotenuse }\approx\text{ 4.5} \end{gathered}[/tex]

Hence, the length of the third leg is 4.5

4.5 is the answer to the question

which equation has a solution of x = 4

Answers

Answer

Option B is correct.

Only the equation, 3x + 9 = 21, has a solution of x = 4.

Explanation

We are told to pick the equation(s) with x = 4 as a solution from the equations,

5x - 8 = 44

3x + 9 = 21

4x = 24

x - 10 = -8

The step to solving this is to insert x = 4 and check if that is consistent with the given equation.

Option A

5x - 8 = 44

If x = 4

5(4) - 8 = 44

20 - 8 = 44

12 ≠ 44

Hence, this is not an answer

Option B

3x + 9 = 21

If x = 4

3(4) + 9 = 21

12 + 9 = 21

21 = 21

Hence, this is an answer for this question.

Option C

4x = 24

If x = 4

4(4) = 24

16 ≠ 24

Hence, this is not an answer to this question.

Option D

x - 10 = - 8

If x = 4

4 - 10 = -8

-6 ≠ -8

This is also not an answer to this question.

Hope this Helps!!!

Using the compound interest formula, determine the total amount paid back and the monthly payment. Buying a $6000 used sedan taken out with $500 paid up front and the rest borrowed at 8.3%annual interest compounded daily (365 days per year) over 2 years.

Answers

The final value of an investment or loan with compound interest is given by:

[tex]FV=P(1+\frac{r}{m})^{m\cdot t}[/tex]

Where P is the initial value (principal or loan), r is the annual interest rate, t is the duration of the investment/loan, and m is the number of compounding periods per year.

The following values are given in the problem:

P = $6000 - $500 = $5500

r = 8.3% = 0.083

t = 2 years

m = 365

Applying the formula:

[tex]FV=5500(1+\frac{0.083}{365})^{365\cdot2}[/tex]

Calculating:

[tex]FV=5500(1+0.0002273926)^{730}[/tex]

FV = $6493.03

The total amount paid back is $6493.03

This is equivalent to an approximate monthly payment of:

[tex]R=\frac{$ 6493.03 $}{24}=270.54[/tex]

The monthly payment is approximately $270.54

CJ loves Girl Scout cookies. He eats 3 cookies per hour. After 5 hours, there are 24 cookies left in the box. Write an equation in slope intercept form. Determine how many hours it will take CJ to eat the entire box of cookies.

Answers

To solve this problem: y will represent the number of cookies, and x the number of hours.

To find the number of cookies that CJ eats per hour, we multiply 3 (since he eats 3 per hour) by x (the number of hours)

Since there we only 24 cookies left in the box, we will need to substract 3 by the number of hours that have passed, from 24 to find the number of cookies "y":

[tex]y=24-3(x-5)[/tex]

This equation represents that the number of cookies "y" is equal to the 24 cookies that where left after 5 hours, and to that we substract 3 (which is the number of cookies per hour) by total number of hours that have passed since those 5 hours (x-5) because 5 hours that have already passed we substract them from x.

We need to simplify that equation to represent in slope-intercept form:

[tex]\begin{gathered} y=24-3x+15 \\ y=-3x+39 \end{gathered}[/tex]

Now we need to determine the number of hours it would take to finish the cookies. So we are looking for the value of x, that makes y=0:

[tex]0=-3x+39[/tex]

solving for the number of hours x:

[tex]\begin{gathered} -3x=-39 \\ x=-\frac{39}{(-3)} \\ x=13 \end{gathered}[/tex]

It would take 13 hours for CJ to eat the entire box of cookies.

The center of a circle and a point on the circle are given. Writecenter: (3,2), point on the circle: (4,3)

Answers

Given:

The center of the circle is the point ( 3, 2 )

And the point on the circle is ( 4, 3 )

To write the equation of the circle, we need to find the radius

The radius = the distance between the center and the point on the circle

so, the radius is the distance between ( 3, 2) and ( 4, 3)

So,

[tex]\begin{gathered} r=d=\sqrt[]{(x_2-x_1)^2+(y_2-y_1)^2} \\ r=\sqrt[]{(4-3)^2+(3-2)^2^{}}=\sqrt[]{1+1}=\sqrt[]{2} \end{gathered}[/tex]

The general equation of the circle is:

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

Where (h, k) is the coordinates of the center of the circle, r is the radius

So,

[tex]\begin{gathered} (h,k)=(3,2) \\ r=\sqrt[]{2} \end{gathered}[/tex]

so, the equation of the circle will be:

Step 1:

We shall state the formula for calculating Z-score.

[tex]\begin{gathered} Z=\frac{X-\mu}{\sigma} \\ \text{Where X}=5\text{00 ( for lower limit) and X=550 for upper limit.} \\ \mu=400 \\ \sigma=50 \end{gathered}[/tex]

Step 2:

We shall substitute the above values in the formula.

[tex]\begin{gathered} \frac{500-400}{50}\leq P(Z)\leq\frac{550-400}{50} \\ \\ \frac{100}{50}\leq P(Z)\leq\frac{150}{50} \\ \\ 2\leq P(Z)\leq3 \end{gathered}[/tex]

Step 3:

We shall read the respective probabilities from the Z score distribution tables.

From the Z-score tables,

P(3) = 99.9 %

P(2) = 97.7 %

To check if Triangles ABE, ADE, and CBE are congruent, let us compute for the distance of each line using the Distance Formula,

[tex]\text{ }d\text{ = }\sqrt[]{(x_2-x_1)^2\text{ + (}y_2-y_1)^2}[/tex]

Where,

d = Distance

(x1, y1) = Coordinates of the first point

(x2, y2) = Coordinates of the second point

Let's compute the distance of the following lines:

Triangle ABE: Lines AB, AE, and BE

Triangle ADE: Lines AD, AE, and ED

Triangle CBE: Lines CE, CB, and BE

For Triangle ABE,

[tex]\text{ d}_{AB}\text{ = }\sqrt[]{(-1-(-4))^2+(3-(-1))^2}\text{ = }\sqrt[]{(-1+4)^2+(3+1)^2}[/tex][tex]\text{ d}_{AB}\text{ = }\sqrt[]{(3)^2+(4)^2}\text{ = }\sqrt[]{9+\text{ 16}}\text{ = }\sqrt[]{25}[/tex][tex]\text{ d}_{AB}\text{ = 5}[/tex][tex]\text{ d}_{AE}\text{ =}\sqrt[]{(1-\text{ }(-1))^2+(0\text{ - }(-4))^2}\text{ = }\sqrt[]{(1+1)^2+(0+4)^2}[/tex][tex]\text{ d}_{AE}\text{ = }\sqrt[]{(2)^2+(4)^2}\text{ = }\sqrt[]{4\text{ + 16}}[/tex][tex]\text{ d}_{AE}\text{ =}\sqrt[]{20}[/tex][tex]\text{ d}_{BE}\text{ = }\sqrt[]{(1\text{ - (}3))^2+(0\text{ - (-1)})^2}\text{ = }\sqrt[]{(1-3)^2+(0+1)^2}[/tex][tex]\text{ d}_{BE}=\text{ }\sqrt[]{(-2)^2+(1)^2}\text{ = }\sqrt[]{4\text{ + 1}}[/tex][tex]\text{ d}_{BE}\text{ = }\sqrt[]{5}[/tex]

For Triangle ADE, let's compute for the distance of line AD and ED since we already got the distance of line AE.

[tex]\text{ d}_{AD}\text{ = }\sqrt[]{(-1-(-1))^2+\text{ (}1\text{ - }(-4))^2}\text{ = }\sqrt[]{(-1+1)^2+(1+4)^2}[/tex][tex]\text{ d}_{AD}\text{ = }\sqrt[]{(0)^2+(5)^2}\text{ = }\sqrt[]{25}[/tex][tex]\text{ d}_{AD}\text{ = 5}[/tex][tex]\text{ d}_{ED}=\text{ }\sqrt[]{(-1\text{ - (}1))^2+(1-0)^2}\text{ = }\sqrt[]{(-1-1)^2+(1)^2}[/tex][tex]\text{ d}_{ED}\text{ = }\sqrt[]{(-2)^2_{}+(1)^2}\text{ = }\sqrt[]{4\text{ + 1}}[/tex][tex]\text{ d}_{ED}\text{ = }\sqrt[]{5}[/tex]

For Triangle CBE, let's compute for the distance of line CE and CB since we already got the distance of line BE.

In summary,

Triangle ABE:

[tex]AB=\text{ 5, AE = }\sqrt[]{20}\text{ and BE = }\sqrt[]{5}[/tex]

Triangle ADE:

[tex]\text{ AD = 5, AE = }\sqrt[]{20}\text{ and ED = }\sqrt[]{5}[/tex]

Triangle CBE: CE, CB, and BE

[tex]\text{ CB = 5, CE = }\sqrt[]{20}\text{ and BE = }\sqrt[]{5}[/tex]

The sides of the three triangles shown in the grid are congruent based on the SSS Rule of Triangle.

Thus, the statement that meets our evaluation is:

D. Triangle ABE, ADE and CBE are all congruent.

Solve the equation for all real solutions. 9z^2-30z+26=1

Answers

Weare given the following quadratic equation, and asked to find all its real solutions:

9 z^2 - 30 z + 26 = 1

we subtract "1" from both sides in order to be able to use the quadratic formula if needed:

9 z^2 - 30 z + 26 - 1 = 0

9 z^2 - 30 z + 25 = 0

we notice that the first term is a perfect square:

9 z^2 = (3 z)^2

and that the last term is also a perfect square:

25 = 5^2

then we suspect that we are in the presence of the perfect square of a binomial of the form:

(3 z - 5)^2 = (3z)^2 - 2 * 15 z + 5^2 = 9 z^2 - 30 z + 25

which corroborates the factorization of the trinomial we had.

Then we have:

(3 z - 5)^2 = 0

and the only way such square gives zero, is if the binomial (3 z - 5) is zero itself, which means:

3 z - 5 = 0 then 3 z = 5 and solving for z: z = 5/ 3

Then the only real solution for this equation is the value:

z = 5/3
