given f (x) = 4x^2+6x+9 find (-7)

Answer:

Because y is a common variable, we can assume that they are equal to each other.

Answer: 150 deg

Step-by-step explanation:

cosine is negative in quadrants 2 and 3. the current angle, 210, is in quad 3. It will have an equal cosine value in quad 2.

that angle will be -210 degrees. in positive terms that is 360-210 = 150 degrees.

thus the answer which shows 150 degrees is correct.

Using the formula for two events not mutually exclusive, the probability of ordering either one is given as 0.8.

Since we assume that the events are not mutually exclusive, this implies that the occurrence of event B is not affected by the probability of occurrence of event A.

Then, the probability of ordering either one is the sum of their individual probabilities minus the probability of ordering both.

The probability formula is:

p (chocolate or vanilla) = p (chocolate) + p (vanilla) - p (chocolate and vanilla)

p (chocolate) = 0.6

p (vanilla) = 0.5

p (chocolate or vanilla) = 0.6 + 0.5 - 0.6 * 0.5

The solution to the integration of the function given, ∫√(5x - 1) dx, is:

[tex]\frac{2}{15}(5x-1)^{3/2} + C[/tex]

To solve the integral of:

√(5x - 1) dx

we can use a u-substitution.

Let u = 5x - 1, then:

du = 5 dx

dx = du/5

Now we can rewrite the integral in terms of u:

∫√(5x - 1) dx = ∫√u * (du/5)

Simplifying the integral:

(1/5) ∫√u du

Integrating √u:

(1/5) * (2/3) * u^(3/2) + C

Where C is the constant of integration

Substituting back u = 5x - 1:

(2/15) * (5x - 1)^(3/2) + C

We are given that side length of the cube measured 18 inches in length. She built another prism (Prism B) with the same dimensions as the cube, except she doubled its height.

When the prism is such that if we slice it horizontally at any height smaller or equal to its original height, the cross-section is same as its base, then its volume is:

V = B x h

So, the volume of the two prism A= V = B x h

V = 18 x h = 18h

Based on the information, it should be noted that the value of tan(A-B) is 234/583.

Given:

tanA = 60/11

sinB = 45/53

A and B are in Quadrant I

We can use the following identity to find tan(A-B):

tan(A-B) = (tanA - tanB)/(1 + tanA*tanB)

Substituting the given values, we get:

tan(A-B) = (60/11 - 45/53)/(1 + (60/11)*(45/53))

= (15/53)/(295/583)

Answer:

n = 10

Step-by-step explanation:

Factorial is denoted by an exclamation mark "!" placed after the number. It means to multiply all whole numbers from the given number down to 1.

Therefore, n! represents the product of all positive integers from 1 to n.

[tex]\boxed{n!=n \times(n-1) \times(n-2) \times ... \times 1}[/tex]

Given expression:

[tex]n! = (2^8)(3^4)(5^2)(7)[/tex]

The expression for n! has been given as the product of prime factors.

As n! represents the product of all positive integers from 1 to n, begin by writing out the positive integers from 1 in ascending order as the product of primes (using exponents where possible):

[tex]\begin{array}{|c|c|c|c|c|c|c|c|c|c|c|c|c|c|}\cline{1-14}\vphantom{\dfrac12}n&1&2&3&4&5&6&7&8&9&10&11&12&13\\\cline{1-14}\vphantom{\dfrac12}\sf Product\;of\;primes&1&2&3&2^2&5&3\cdot 2&7&2^3&3^2&5 \cdot 2&11&2^2\cdot 3&13\\\cline{1-14}\end{aligned}\;\;\sf etc.[/tex]

If we examine the prime products of the given expression, we can see that largest prime number 7 appears only once. Therefore, n must be less than 14, since the next time 7 appears as a prime factor is when 2 · 7 = 14.

The prime number 5 appears twice in the given expression.

From the above table, we can see that the first two times the number 5 is present is (1) on its own, and (2) as a factor of 10. Therefore, n must be equal to or more than 10.

The prime number 3 appears four times in the given expression.

From the above table, we can see that the first four times the number 3 is present is (1) on its own, (2) as a factor of 6, (3) & (4) as both factors of 9.

The 5th time prime number 3 is present is as a prime factor of 12. Therefore, n must be less than 12, else 2⁵ would be a factor of n!.

Therefore, we have determined that 10 ≤ n < 12.

As 11 is a prime number and does not appear in the given expression for n!, we can conclude that n = 10.

We can check this by calculating the given expression and 10!:

[tex]\begin{aligned}n! &= (2^8)(3^4)(5^2)(7)\\&=256 \cdot 81\cdot25\cdot7\\&=20738\cdot25\cdot7\\&=518400\cdot7\\&=3628800\end{aligned}[/tex]

Answer:

2/3=10/15

3/5=9/15

Step-by-step explanation:

In order to turn 2/3 and 3/5 using 15 as the common denominator, we must first find out how much we need to multiply the denominator by to get 15 and use that amount to also multiply the numerator. In 2/3 the 3 needs to be multiplied by 5, therefore we also multiply the 2 by 5 giving us the result of 10/15 for the 2/3 problem. For the 3/5 we use the same tactic. The 5 in 3/5 needs to be multiplied by 3 to get to 15, therefore we multiply the 3 by 3 as well to get 9/15.

Answer:

To calculate the cost of the mortgage, we need to find the total amount that Sonya will pay back over the 25-year period.

One way to do this is to use the formula for the future value of an annuity, which is:

FV = Pmt x ((1 + r)^n - 1) / r

where FV is the future value, Pmt is the periodic payment, r is the interest rate per period, and n is the number of periods. In this case, we want to find the total future value of the mortgage payments over 25 years, so we can set Pmt equal to the monthly mortgage payment, r equal to the monthly interest rate, and n equal to the total number of months in 25 years.

First, let's convert the annual interest rate to a monthly interest rate by dividing by 12:

r = 7% / 12 = 0.00583

Next, we can use an online mortgage calculator or a spreadsheet to find the monthly mortgage payment based on the loan amount, interest rate, and term. For a $65,000 mortgage at 7% for 25 years, the monthly payment is approximately $471.78.

Finally, we can plug in the values into the formula for the future value of an annuity:

FV = $471.78 x ((1 + 0.00583)^300 - 1) / 0.00583

FV ≈ $141,535.15

Therefore, the total cost of the mortgage over 25 years is approximately $141,535.15. This includes the original loan amount of $65,000 plus the interest that accumulates over the 25-year period.

The marksman hit 54% of the targets last year when expressed as a percentage, based on hitting 27 out of 50 targets from a distance of 100 yards.

From the given information, we know that a marksman hit 27 out of 50 targets last year from a distance of 100 yards.

To analyze this data, we can calculate the hit rate or success rate of the marksman. The hit rate is calculated by dividing the number of hits by the total number of attempts or trials.

Hit rate = Number of hits / Total number of attempts

In this case, the number of hits is 27, and the total number of attempts is 50.

Hit rate = 27 / 50

Simplifying the fraction, we get:

Hit rate = 0.54 or 54%

Therefore, the marksman had a hit rate of 54% last year.

This means that out of the 50 targets attempted from a distance of 100 yards, the marksman successfully hit 27 of them.

The hit rate serves as a measure of accuracy and effectiveness in target shooting. A higher hit rate indicates a higher level of skill and precision.

It's important to note that other factors such as weather conditions, visibility, and the difficulty level of the targets can influence the hit rate. Additionally, the marksman's skills may improve or vary over time, so this hit rate represents their performance specifically for the past year.

By analyzing the hit rate, we can gain insights into the marksman's accuracy and assess their proficiency in target shooting from a distance of 100 yards.
