What is the surface area of the square pyramid?

hearts:stars

the ratio

Answer:

$4,555

Step-by-step explanation:

According to the scenario, calculation of the given data are as follows,

Total deposit (P) = $2,500

Annual interest (r) = 12%

Time period (t) = 5 years

We can calculate the balance after 5 years if compounded continuously by using following formula,

FV = P[tex]e^{rt}[/tex]

By putting the value, we get

FV = $2,500 × [tex]e^{(0.12 * 5)}[/tex]

= $2,500 ×[tex]e^{.60}[/tex]

= $2,500 × 1.822

= $4,555

Answer:

b. 106 sq.cm

Step-by-step explanation:

A=L×W

A1= 2(5×8) = 2(40) = 80

A2= 2(1×8) = 2(8) = 16

A3= 2(5×1) = 2(5) = 10

Total area = 80 + 16 +10 = 106 sq. cm

Answer:

Read explanation, you gotta know how

Step-by-step explanation:

Step 1: What I do is pretty much find where you want the dot to be, which in this case is between the 2 and the 4.

Step 2: right now the dot is all the way to the right, so we gotta move it to the left.

Step 3: start moving the dot to where you want it to be (inbetween the 2 and the 4) and make sure to count how many times you move the dot Left, until you reach the point you want it to be.

step 4: now you have the dot where you want it to be, and you counted how many times you moved the do to get there (Should look like this now= 2.437) you dont need the zeros anymore because 2.43700000 is the same as 2.437.

Step 5: add the scientific notation thing which is (Number) x 10^ (the amount of times you moved the dot to the left)

Step 6: now you have the answer which is 2.347 x 10^8 (dont just skip all the explanation to do this, If you learn how you wont need to waste your points asking the same question again.)

Answer:

d. Electronic Tango, Tango Fusion, Argentine Tango and more

Step-by-step explanation:

In the figure,

height of triangle = 10m

base of triangle/Diameter of circle = 14m

radius = 7m

Area of triangle = 1/2 × b × h

= 1/2 × 14 × 10

= 7 × 10

= 70m²

Area of semi-circle = 1/2 × pi × r²

= 1/2 × 3.14 × 7²

= 76.93m²

Area of the figure = 70 + 76.93 = 146.93m²

Answer:

the object is in the air on the time interval (0.24 sec, 6.51 sec)

Step-by-step explanation:

The object is 'in the air' for all t such that h> 0.  We need to find the roots of h = -16t^2 + 108t - 25 = 0.  From the graph we see that both t values are positive.  Once we find them, we subtract the smaller t from the larger t, which results in the length of time the object is in the air.

Use the quadratic formula to find the roots of h(t).  The coefficients of t are {-16, 108, -25}, and so the discriminant b^2 - 4ac is

108² - 4(-16)(-25) = 11664 - 1600 = 10064, whose square root is 100.32.

Then the quadratic formula x = (-b ± √[b² - 4ac)/(2a) becomes

      -108 ± 100.32       108 ± 100.32

t = ---------------------- = --------------------- = 3.375 ± 3.135

             2(-16)                      32

or t = 6.51 or t = 0.24  (both times expressed in seconds).

So, again, the object is in the air on the time interval (0.24 sec, 6.51 sec)

People firstly believe that the planets move in a circular orbit until Newton came up with his hypothesis by inventing calculus so that we could understood and calculated planetary orbits and their accuracy.

Explanation:

Everyone assumed the planets were perfect circles until Newton came up with an idea. Slowly people would make maps of the orbits that added circles on circles, and they could never really explain about the movement of the planet. They simply say that planets move on circles but they lacked the math to explain or prove it. Then Newton came up with an idea of inventing calculus so that we could understood and calculated planetary orbits and their accuracy.

Firstly people used their observations and say that the orbits looked like circles, then they developed their models and did the math, and proposed their hypothesizes which were wrong, until Newton came along and tried to match a model that used elliptical orbits and invented the math that allowed him to make predictions with it. His model worked for most planets.

However he could not explain about the planet Mercury for instance since it was a very strange orbit. Then after the Einstein's theory of General Relativity he could also explain very deeply about it.

Scientists and Astronomers made hypothesizes that there was another planet orbiting too close to the sun to see with telescopes, called Vulcan, that explained mercury's orbit before Einstein's theory. Then long after we had telescopes which was good enough to see if there was a planet orbiting closer to the sun than mercury.

Answer:

You save $266. The television costs $2394.

Step-by-step explanation:

10% off the original price is $266. The television is 10% off, meaning the new price is 90% of the original price. Therefore, you can subtract $2660 - $266 or multiply 90% × $2660.

ANSWER: 1 SOLUTION

Step 1: Subtract 2x-1 from both sides.

x2−(2x−1)=2x−1−(2x−1)

x2−2x+1=0

Step 2: Factor left side of equation.

(x−1)(x−1)=0

Step 3: Set factors equal to 0.

x−1=0 or x−1=0

x=1

Answer:

x=1

Answer:

7. 60%

Step-by-step explanation:

Step-by-step explanation:

The exact question is as follows :

Given - The student who traveled to 3 states visited 6 new states during a vacation.

To find - Does increasing the 3 to 6 change the​ median? If​ so, how?

Proof -

Yes,

If we increase the 3 states to 6 states, it changes the median

Because

The median of the first 3 states is the middle state.

For example -

If we have 3 states X, Y, Z

Then the median is the state Y

Now,

The median of 6 states is the average of the 2 middle states.

For example -

If we have 6 states

X, Y, Z, U, V, W

Then

The median is not explicit.

Median is the average of the two middle states, Z and U.

And

Average of Z and U =  half of the sum of Z and U.

i.e.  (Z + U)/2.

And we can see that,

Median of 3 States is not equal to Median of 6 states

i.e. Y is not equal to (Z + U)/2.

So,

We can say that,

Increasing the state 3 to 6 changes the​ median.

Answer:

a = 4[tex]\sqrt{5}[/tex]

Step-by-step explanation:

pythagorean theorem:

a² + 8² = 12²

a² + 64 = 144

a² = 80

a = [tex]\sqrt{80}[/tex]

a = [tex]\sqrt{4}[/tex]·[tex]\sqrt{4}[/tex]·[tex]\sqrt{5}[/tex] which simplifies to be 4[tex]\sqrt{5}[/tex]

Answer:

y = -3

Step-by-step explanation:

-3 (y-5) = 24

divide both sides by negative 3
