To answer this question, we need to remember that a ratio is a comparison of two or more units. We can also need to have into account that these units must be in the same units.

We have one of the quantities is 6ft, the other is equal to 78 inches. We can convert 6ft to its equivalent in inches, or 78 inches into its equivalent in feet. Then, we have:

[tex]6ft\cdot\frac{12in}{1ft}=72in[/tex]Then, we can conclude that the ratio of 6feet (72 inches) to 78 inches is equivalent to:

[tex]\text{Ratio}=\frac{72in}{78in}=\frac{12}{13}\Rightarrow Ratio=\frac{12}{13}[/tex]Help me asp please!!

A group of friends were working on a student film. They spent all their budget on equipment and props. They spent $369 on equipment and 55% of the total budget on props. What was the total budget for their student film

**Answer: t = 820**

**Step-by-step explanation:**

**1) Set up the equation**

369 + 55%t = t

**2) Simplify the percentage**

369+ 0.55t = t

**3) Minus 0.55 t on both sides**

369 = 0.45t

**4) Set t by itself.**

**t = 820**

what is the arc measure of ct in radians? what is the arc length in feet?

We will determine the arch lenght (In radians) as follows:

*First: We transform the measure of the angle from degrees to radians, that is:

[tex]\theta=80\cdot\frac{\pi}{180}\Rightarrow\theta=\frac{4\pi}{9}[/tex]*Second: We find the arc length:

[tex]s=r\theta\Rightarrow s=(13.2)(\frac{4\pi}{9})[/tex][tex]\Rightarrow s=\frac{88}{15}\pi[/tex]So, **the arc length for CT is 88pi/15 radians.**

*Third: We find its measure in feet:

[tex]s\approx18.43[/tex]So, **the arch length for CT in feet is approximately 18.43 feet.**

Create a data set that has 4 values with a mode of 3, a median of 6, and a meanof 10

We are to create a data set of 4

that is a, b, c, d

mode means a number that occur the most

Median means the middle number

Mean means the average number

in the set, we must have a mode of 3

3, 3,

to get a median of 6, we need a number when we add to three and divide by 2 will give us 6

the number is 9

3 + 9 / 2

12/ 2 =

3, 3 , 9, d

the last number is d and it is unknown

since means is 10

mean = summation of all the numbers in the data set / the total number

the total number is 4

mean = 10

10 = 3 + 3 + 9 + d / 4

cross multiplication

10 x 4 = 3 + 3 + 9 + d

40 = 6 + 9 + d

40 = 15 + d

isolate d

d = 40 - 15

d = 25

therefore, the data set with a mode of 3, median of 6 and a mean of 10 are

3 , 3 , 9, 25

How do I solve this problem?By using the pythagorean identities.

Given the equation:

[tex]\sin ^2x(\csc ^2x-1)[/tex]Using the Pythagorean identities

so,

[tex]\csc ^2x-1=\cot ^2x[/tex]so, the equation will be:

[tex]\begin{gathered} \sin ^2x\cdot\cot ^2x \\ \\ =\sin ^2x\cdot\frac{\cos ^2x}{\sin ^2x} \\ \\ =\cos ^2x \end{gathered}[/tex]Write the domain and range of g as intervals or unions of intervals

It's important to know that **empty circles** refer to open intervals or parenthesis.

In this case, we observe that the first interval of the domain is (-1, 1) and the second interval of the domain is (2, 5), so the whole domain would be the union of these two intervals.

[tex]\text{Domain}=(-1,1)\cup(2,5)[/tex]To obtain the range, let's observe the y-values. The function goes from y = -5 to y = 3, so the range would be

where:

r is the radius

A space shuttle is moving in a straight line and is traveling at a constant speed. It takes 3 hours to get from A to B and 1 hour to get from B to C. Relative to a suitable set of axes, A is the point (4,-1,7) and B is the point (16,-10,10). Find the coordinates of C.

We will solve as follows:

First: We will use the i, j, k vector notation to describe each point as a vector:

[tex]A=4i-j+7k[/tex][tex]B=16i-10j+10k[/tex]Now, we have that the time it takes to get from A to B is 3 hours (t1). And the time it takes from B to C is 1 hour (t2).

Second: We determine the speed from A to B:

[tex]v=\frac{B-A}{t_1}\Rightarrow v=\frac{(16-4)i+(-10+1)j+(10-7)k}{3}[/tex][tex]\Rightarrow v=\frac{12i-9j+3k}{3}\Rightarrow v=4i-3j+k[/tex]Third: We now determine the value of C:

[tex]C=B+vt_2\Rightarrow C=(16+4)i+(-10-3)j+(10+1)k[/tex][tex]\Rightarrow C=20i-13j+11k[/tex]So, we would have that the coordinates of C are:

[tex]\begin{gathered} x\rightarrow(-\frac{1}{2})^-;f(x)\rightarrow\infty \\ x\rightarrow(-\frac{1}{2})^+;f(x)\rightarrow-\infty \\ x\rightarrow\infty;f(x)\rightarrow\frac{1}{2} \\ x\rightarrow-\infty;f(x)\rightarrow\frac{1}{2} \end{gathered}[/tex]The graph of the function is as follows:

Write a function to model the geometric sequence in the table. n: (1 2 3 4 5)a: (75 15 3 3/5 3/25)a) f(n) = 75 (1/5) nb) f(n) = 75 (1/5) n-1c) f(n) = 1/5 (75) nd) f(n) = 1/5 (75) n-1

First let's find the ratio of the sequence, by dividing one term by the term before:

[tex]\begin{gathered} \text{second term: 15} \\ \text{first term: 75} \\ ratio=\frac{15}{75}=\frac{1}{5} \end{gathered}[/tex]So the ratio is 1/5 and the first term is 75.

Now, we can use the following formula for the nth term of a geometric sequence:

[tex]a_n=a_1\cdot q^{n-1}[/tex]Where q is the ratio and a1 is the first term. So we have:

[tex]a_n=75(\frac{1}{5})^{n-1}[/tex]Substituting an by the function f(n), we have:

[tex]f(n)=75(\frac{1}{5})^{n-1}[/tex]So **the correct option is b)**

The **two-tangent theorem** states that if two **tangents** are drawn from a circle to meet at a point outside the circle, then the **tangent segments** are congruent to each other, that is they have equal lengths.

Segments LK and LM are **tangent segments** drawn to meet at the external point L. This means, the length of Lk and the length of LM would be equal to each other.

LK = 4x - 2

LM = 3x + 3

LK = LM

**To Find - **

How many positive real zeroes does f(x) have =?

**Step-by-Step Explanation -**

We have

f(x) = x⁵ - 4x³ + 7x² + 3x - 5

where the signs of coefficients are:

+ - + + -

We can see there are three changes in the sign in f(x).

So, from

Descarte's rule,

there are either 3 0r 1 positive real roots

Now,

f(-x) = -x⁵ + 4x³ + 7x² - 3x - 5

Signs: - + + - -

So, here f(-x) has two sign changes.

From this we can conclude there is at least 1 real root and either 4, 2 or 0 imaginary roots.

**Final Answer - **

**Positive real zeroes f(x) have = **

**Minimum = 1**
