Answer:

The correct answer option is B. 0.21.

Step-by-step explanation:

We are to find the value of [tex]cos \theta[/tex] using the law of cosines.

We know that the formula of the cosine rule is given by:

[tex] c ^ 2 = a ^ 2 + b ^ 2 - 2 a b cos C [/tex]

So substituting the given values in the above formula:

[tex] 10.9 ^ 2 = 5.8 ^ 2 + 10.5 ^ 2 - 2 (5.8) (10.5) cos C [/tex]

[tex]118.81=33.64+110.25-121.8cosC[/tex]

[tex]118.81 - (33.64+110.25) = -121.8cosC[/tex]

[tex]118.81-143.86=-121.8cosC[/tex]

[tex]cosC=\frac{-25.05}{-121.8}[/tex]

cos C = 0.21

Step-by-step explanation:

You take the number of shirts you have and are focusing on. In this case concert (12) and divide it by the total number of shirts to get the expected.

You can use the fact when random picking of t shirts happen, the probability of picking the Concert shirt can be taken by number of concert t shirts in total number of shirt since there is no bias towards a particular t shirt except their frequency.

The frequency of  concert shirts obtained out of selected shirts compare to the expected frequency of the concert shirt as:

Option A: The frequency is 1 fewer that expected.

Suppose there are 100 fruits and 50 of them are apples and 50 other are mangoes. Then we can say that each one of the two fruit is apple and other one is mango. This 1 apple per 2 fruit is telling frequency of apples in selected 2 fruits.

Frequency is number of amount that item is present in the selected group.

The expected frequency can be obtained by seeing how many such objects are available to how many total objects.

You can think of expected frequency as how many of the considered object we expect to be present in the total amount of objects.

Thus, we have:
Expected frequency for concert shirt is 12 per 30 shirts or 4 per 10( i divided by 3) shirts or 2 per 5 shirts ( divided by 2). You can convert this to percent or probability too or ratio too like

2:5 = 2/5 = 0.4 = 40% (all four represent how many of the concert shirts are expected to be present out of amount of total shirts selected).

The frequency obtained from the selection contains 3 concert shirts out  of 10 selected shirts.

Since the expected frequency of the concert shirts per 10 shirts selected is 4, and the frequency we obtained is 3, thus. the frequency obtained is 1 fewer than the expected.

Thus,

Option A: The frequency obtained is 1 fewer than expected.

Step-by-step explanation:

You want terms that have a common ratio of 3, so the term in the summation will be 3 to some power. Only the first expression matches that requirement.

You can try different values of n to see if they fit the problem description.

  n = 1: 1(3)^0 = 1(1) = 1

  n = 2: 1(3)^1 = 1(3) = 3

  n = 3: 1(3)^2 = 1(9) = 9 . . . . . the third triangle in the set has 9 shaded triangles, as this expression predicts. Thus, we see the problem description being matched by the first answer choice shown.

Answer:

Jordan will save $16.25 each month by choosing financing through the dealership.

Step-by-step explanation:

The EMI formula is :

[tex]\frac{p\times r\times(1+r)^{n}}{(1+r)^{n}-1}[/tex]

Case 1:

p = 17500

r = [tex]6.9/12/100=0.00575[/tex]

n = [tex]5\times12=60[/tex]

Putting the values in formula;

[tex]\frac{17500\times0.00575\times(1+0.00575)^{60}}{(1+0.00575)^{60}-1}[/tex]

=> [tex]\frac{17500\times0.00575\times(1.00575)^{60}}{(1.00575)^{60}-1}[/tex]

EMI = $345.70

Case 2:

p = 17500

r = [tex]4.9/12/100=0.004083[/tex]

n = [tex]5\times12=60[/tex]

Putting the values in formula;

[tex]\frac{17500\times0.004083\times(1+0.004083)^{60}}{(1+0.004083)^{60}-1}[/tex]

=> [tex]\frac{17500\times0.004083\times(1.004083)^{60}}{(1.004083)^{60}-1}[/tex]

EMI = $329.45

So, difference per month in payments will be :

[tex]345.70-329.45=16.25[/tex] dollars

Hence, Jordan will save $16.25 each month by choosing financing through the dealership.

Answer:

Below

Step-by-step explanation:

The dish had intially 2500 bacteria. The bacteria triples every month.

So after a month the number will be 7500 =>(2500×3)

So let 2500 be the n0 and 7500 be n1

● n1 = 3×n0

Following the same way we get:

● n2= 3× n1

● n3 = 3× n2

If we kept repeating the same process we will get:

● n9 = n8 × 3

n9 is the number of Bacteria during the 10th month

let's calculate n9.

● n9 = n8 × 3

● n9 = n0 × 3^10

● n9 = 2500 × 3^10

● n9 = 147 622 500

● n9 = 1.476225 ÷ 10^8

The number of bacteria will be 147,622,500 in 10 months according to the GP.

A geometric progression (GP), sometimes known as a geometric sequence, is a series of integers that differ by a common ratio.

Given, The dish had initially 2500 bacteria. The bacteria triples every month. So after a month, the number will be (g1) = 2500 * 3 = 7500. Since data is in geometric progression where ratio (r) is 3 and first term (a) is 7500.

Hence, the nth term of GP (Tₙ)  = a * rⁿ⁻¹

10th term of Given GP (T₁₀) = 7500 * 3¹⁰⁻¹ = 147,622,500

Therefore, 147,622,500 bacteria will be there in the petri dish after 10 months

Answer:

(x−4)² + (y−5)² = 36

Step-by-step explanation:

The equation of a circle is:

(x−h)² + (y−k)² = r²

where (h, k) is the center and r is the radius.

If the center is (4, 5) and the radius is 6, then the equation is:

(x−4)² + (y−5)² = 6²

(x−4)² + (y−5)² = 36

All of the right triangles are similar by AA similarity, so corresponding side lengths are proportional. The ratio of the long leg to the short leg is the same for the two smaller triangles, for example:

  CP/AP = MP/CP

  CP/9 = 16/CP . . . . . fill in the given numbers

  CP² = 9·16 . . . . . . . multiply by 9·CP

  CP = 3·4 = 12 . . . . . take the square root

Now, you can use the Pythagorean theorem to find AC and/or CM.

  AC = √(9² +12²) = √225 = 15

  CM = √(12² +16²) = √400 = 20

In summary, CP = 12, AC = 15, CM = 20.

_____

Once you have CM, you can see these are 3-4-5 right triangles, so you can determine the other lengths by using these side ratios.

  3:4:5 = 9:12:15 = 12:16:20

_____

The altitude CP is called the "geometric mean" of AP and MP. It is the square root of their product. This is true for any right triangle, not just one with sides in the ratio 3:4:5. If you know this, you can write down your answers almost immediately. Above, we had to derive this fact using similarity.

5/6 + 3/4

Find a common denominator, aka least common multiple

So, 5/6 becomes 20/24 and 3/4 becomes 18/24

20/24 + 18/24 = 38/24 which simplifies to 19/12 or 1 7/12

Answer:

19/12 pounds which is equal to 1.583 pounds

Step-by-step explanation:

The total pounds of beans bought is a function of the amount of black beans and the amount of pinto beans. These two added together gives the amount of beans bought.

Given,

Amount of black beans = 5/6 pounds

Amount of Pinto beans = 3/4 pounds

Total pounds of beans purchased = 5/6 + 3/4

=(10 + 9)/12

= 19/12 pounds

= 1.583 pound

Option b.  sum of all areas of faces

Step-by-step explanation:

we know that

The surface area of the prism is equal to the area of its bases plus the area of its four rectangular lateral faces

so

[tex]SA=2B+PH[/tex]

where

B is the area of the base

P is the perimeter of the base

H is the height of the prism

therefore

sum of all areas of faces

Answer:

Option B would be correct.

Step-by-step explanation:

The general formula for the total surface area of a right prism is T. S. =ph+2B where p represents the perimeter of the base, h the height of the prism and B the area of the base. There is no easy way to calculate the surface area of an oblique prism in general.

To find the total surface area of a prism, you need to calculate the area of two the polygonal bases i.e. the top face and bottom face. And then calculate the area of lateral faces connecting the bases. Add up the area of the two bases and the area of the lateral faces to get the total surface area of a prism.

Therefore, it would be option B.
