Please help me 15 point

Answer:

7, 10.5, 14  

because you have to keep adding 3.5 like from 3.5 you add another 3.5 to get the 7.

Answer:

We conclude that:

f(a) + 5 = a² + 8a - 5

Step-by-step explanation:

Given

The function is given by

f(x) = x²+8x-10

To determine

f(a)+5

In order to determine f(a)+5, first, we need to determine f(a).

Now substitute x = a in the function f(x) = x²+8x-10

f(a) = (a)² + 8(a) - 10

f(a) = a² + 8a - 10

Thus,

f(a) + 5 = (a² + 8a - 10) + 5

f(a) + 5 = a² + 8a - 5

Therefore, we conclude that:

f(a) + 5 = a² + 8a - 5

The area of the circle: pi times radius squared soo

radius 2cm divided by 2 equals 1 cm so pi times radius squared 3.14 × 1 squared so ur answer is 3.14

Answer:

A. end up at exactly 0 feet of elevation.

Step-by-step explanation:

This is because, at a depth of 20 feet, their position is -20 feet below the water surface. If they rise by 20 feet, we add 20 feet to their current position to reach their new position.

So, -20 feet + 20 feet = 0 feet.

So, their new elevation will end up at exactly 0 feet of elevation.

Answer:

Infinitely many solutions

Step-by-step explanation:

These equations are the same. The only difference being one is written in fractions and the other is in decimals. Since they are the same, they will have infinitely many solutions.

Answer: what is the question

Step-by-step explanation:

Answer:

[tex]P(X=2) = 0.1047[/tex]

Step-by-step explanation:

Represent the probability of hitting the target with H.

So:

[tex]H = \frac{1}{8}[/tex]

Represent the probability of not hitting the target with T.

So:

[tex]T = 1 - H[/tex]

[tex]T =1 - \frac{1}{8}[/tex]

[tex]T =\frac{7}{8}[/tex]

Required

Probability of exactly 2 hits in 5 tries

This probability is a binomial probability and will be calculated using:

[tex]P(X=x) = ^nC_x H^xT^{n-x}[/tex]

In this case:

[tex]x = 2[/tex] i.e 2 hits

[tex]n = 5[/tex] i.e. 5 attempts

So, we have:

[tex]P(X=2) = ^5C_2 H^2T^{5-2}[/tex]

[tex]P(X=2) = ^5C_2 H^2T^3[/tex]

Apply combination formula:

[tex]P(X=2) = \frac{5!}{(5-2)!2!} H^2T^3[/tex]

[tex]P(X=2) = \frac{5!}{3!2!} H^2T^3[/tex]

[tex]P(X=2) = \frac{5*4*3!}{3!2*1} H^2T^3[/tex]

[tex]P(X=2) = \frac{5*4}{2} H^2T^3[/tex]

[tex]P(X=2) = 10* H^2T^3[/tex]

Substitute values for H and T

[tex]P(X=2) = 10* (\frac{1}{8})^2(\frac{7}{8})^3[/tex]

[tex]P(X=2) = 10* \frac{1}{64}*\frac{343}{512}[/tex]

[tex]P(X=2) = \frac{3430}{32768}[/tex]

[tex]P(X=2) = 0.1047[/tex]

Hence, the probability of 2 hits in 5 tries is 0.1047

Answer:

Mean    μ = 5.75

Standard deviation  σ = 2.1041

Step-by-step explanation:

Step(i):-

Given that the size of the sample 'n' = 25

Given proportion p= 23% = 0.23

Let 'X' be the random variable in a binomial distribution

Mean    μ = np = 25 × 0.23 = 5.75

Step(ii):-

Standard deviation

          σ = √npq

         σ = [tex]\sqrt{25 X 0.23 X0.77}[/tex]

        σ = 2.1041

Step-by-step explanation:

18x³y⁴ = 2 * 3 * 3 * x³ * y⁴

24x²y⁵ = 2 * 2 * 2 * 3 * x² * y⁵

GCF = 2 * 3 * x² * y⁴ = 6x²y⁴

18x³y⁴ + 24x²y⁵ = 6x²y⁴(3x  + 4y)

Answer: 6x^2 - 9x + 3

Step-by-step explanation:

first, i multiplied the parentheses.

3x x 2x - 3x - 3 x 2x - 3 x (-1)

then, i calculated/multiplied it.

6x^2 - 3x - 6x + 3

finally, i collected the like terms.

6x^2 - 9x + 3

Answer:

6x^2-9x+3

Answer

Step-by-step explanation:

Answer:

The correct answer is C. President Wilson included resolutions specifically about European territories in his Fourteen Points because territorial disputes among European nations were a major reason the war began in the first  place.

Step-by-step explanation:

The Fourteen Points were the pacifist plan devised by President Woodrow Wilson at the end of World War I, with the aim of avoiding tensions between the former European combatants of the conflict and thus achieve a lasting peace between nations, framed in the League of Nations as supranational entity. Basically, the Fourteen Points sought to avoid the imposition of excessive sanctions on the defeated, as well as the obtaining of great benefits by the winners, so as not to break the territorial status quo prior to the war and thus avoid generating tensions in the future.

Answer:

C.) Territorial disputes among European nations were a major reason the war began in the first place.

Answer:

The total purchase price is $370.97.

Step-by-step explanation:

Given;

price of the 35-mm camera, =  $259.99

price of the wide-angle lens = $89.99

TAX rate = 6% = 0.06

The total purchase price = 0.06($259.99 + $89.99) + ($259.99 + $89.99)

The total purchase price = $20.99 + 349.98

The total purchase price = $370.97

Therefore, the total purchase price is $370.97.

Answer:

[tex]y = 4x - 12[/tex]

Step-by-step explanation:

The equation of a line has the following format:

[tex]y = mx + b[/tex]

In which m is the slope and b is the y-intercept(value of x when y = 0).

In this question:

Slope 4, which means that [tex]m = 4[/tex].

So

[tex]y = 4x + b[/tex]

Contains point (1,-8).

This means that when [tex]x = 1, y = -8[/tex]. We replace this into the equation to find b. So

[tex]y = 4x + b[/tex]

[tex]-8 = 4(1) + b[/tex]

[tex]b = -12[/tex]

So

[tex]y = 4x - 12[/tex]

f(x)=11x+12

Step-by-step explanation:

it shows that the intercept is around halfway between 0 and 20, and the plots are not exactly at the 10s marks, if you look- June is supposed to be 6, but it’s closer to 66. since 6*11=66, i’d say 11x+12 is the answer.

Answer:

The answer is below

Step-by-step explanation:

Trigonometric functions are functions used in right angled triangles to relate an angle in the triangle to the ratio of two side. The most common trigonometric functions are the sine, the cosine, and the tangent.

Some trigonometric identities are:

secθ = 1/ cosθ, cosecθ = 1 / sinθ, tanθ = sinθ / cosθ, cotθ = 1 / tanθ = cosθ / sinθ.

Hence simplifying the question:

[tex]\frac{sin\theta}{cos\theta tan\theta} =\frac{sin\theta}{cos\theta *\frac{sin\theta}{cos\theta} }\\\\=\frac{sin\theta}{sin\theta}\\\\=1[/tex]
