Derive the equation of the parabola with the focus
is (-7,5) and the directrix of y=-11

Answers

so, notice, the focus point is at -7, 5, and the directrix is at y = -11.

keep in mind that the vertex is half-way between those two fellows, and the distance from the vertex to either one of them is "p" units, check the picture below.

with that focus point and that directrix, the half-way over the axis of symmetry will be -7, -3, that's where the vertex is at, and notice the distance "p", is 8 units.

since the parabola is opening upwards, "p" is positive 8.

[tex]\bf \textit{parabola vertex form with focus point distance}\\\\ \begin{array}{llll} 4p(x- h)=(y- k)^2 \\\\ \boxed{4p(y- k)=(x- h)^2} \end{array} \qquad \begin{array}{llll} vertex\ ( h, k)\\\\ p=\textit{distance from vertex to }\\ \qquad \textit{ focus or directrix} \end{array}\\\\ -------------------------------\\\\ \begin{cases} h=-7\\ k=-3\\ p=8 \end{cases}\implies 4(8)[y-(-3)]=[x-(-7)]^2 \\\\\\ 32(y+3)=(x+7)^2\implies y+3=\cfrac{1}{32}(x+7)^2 \\\\\\ y=\cfrac{1}{32}(x+7)^2-3[/tex]

Form a seven-letter word by mixing up the letters in the word FIXTURE.
How many ways can you do this if no vowel is isolated between two consonants?

Answers

There are 4 consonants and 3 vowels. If the vowels can't be isolated between two consonants then the vowels would have to be right next to each other. Let's consider the vowels as a group so that they can be arranged in 3!=6 ways and the consonants 4!=24 ways. So:
6x24=144ways

You have the main rule: no vowel is isolated between two consonants.

The word FIXTURE consists of 4 consonants and 3 vowels.

There are such possible cases:

1. Formed word begins with three vowels and ends with 4 consonants.

The number of such words is [tex]3!\cdot 4!=6\cdot 24=144.[/tex]

2. Formed word begins with two vowels and ends with one vowel (between them stand all consonants).

The number of such words is [tex]3\cdot 2!\cdot 4!=6\cdot 24=144.[/tex]

3. Formed word begins with one vowel and ends with two vowels (between them stand all consonants).

The number of such words is [tex]3\cdot 2!\cdot 4!=6\cdot 24=144.[/tex]

4. Formed word begins with with 4 consonants and ends with 3 vowels.

The number of such words is [tex]3!\cdot 4!=6\cdot 24=144.[/tex]

5. In total 144+144+144+144=576 different words.

Solve the inequality and graph its solution: 2t + 1 > 9 or –18 > 5t – 3

Answers

Final answer:

To solve the inequality and graph its solution, solve the two separate inequalities: 2t + 1 > 9 and -18 > 5t - 3. The solution is t > 4 or t < -3.6. Graph the solution by plotting the points 4 and -3.6 on a number line, and shading the area to the right of 4 and the left of -3.6.

Explanation:

To solve the inequality and graph its solution, we need to solve the two separate inequalities:

1) 2t + 1 > 9

2) -18 > 5t - 3

For the first inequality, we can subtract 1 from both sides and divide by 2 to obtain t > 4.

For the second inequality, we can add 3 to both sides and divide by 5 to obtain t < -3.6.

Thus, the solution to the original inequality is t > 4 or t < -3.6.

To graph the solution, we would plot the points 4 and -3.6 on a number line, and shade the area to the right of 4 and the left of -3.6.

Final answer:

To solve the inequalities 2t + 1 > 9 and –18 > 5t – 3, we must solve each separately, and since it's an 'or' inequality, we combine the solution sets. The solutions are t > 4 and t < -3. Graphically, these solutions represent non-overlapping shaded regions on a number line.

Explanation:

To solve the inequality 2t + 1 > 9 or –18 > 5t – 3, we need to consider them separately as each inequality represents a different solution set.

For the first inequality:

Subtract 1 from both sides to obtain 2t > 8.Divide by 2 to isolate t, yielding t > 4.

For the second inequality:

Add 3 to both sides to get –15 > 5t.Divide by 5, which flips the inequality because we are dividing by a positive number, resulting in t < –3.

We interpret these results as two separate conditions:

t > 4: This suggests that t is any value greater than 4.t < –3: This suggests that t is any value less than -3.

Since the original statement uses 'or', the solution set includes all the values that satisfy either inequality. Therefore, graphically, we would show these on a number line with a shaded region to the right of 4 and another shaded region to the left of -3. The areas do not overlap because there are no t values that can simultaneously be greater than 4 and less than -3.

can someone help me with number 4

Answers

Let m = the number of member tickets.
Let n = number of nonmember tickets.
Let c = total cost

m number of member tickets cost 10m.
n number of nonmember tickets cost 24n.

The total cost is the sum of the two expressions.

c = 10m + 24n

Now we replace m w2 and n with 4, and we evaluate the expression.

c = 10m + 24n

c = 10(2) + 24(4)

c = 20 + 96

c = 116

Quadrilateral ABCD is inscribed in this circle. What is the measure of angle C? Enter your answer in the box
https://static.k12.com/nextgen_media/assets/8120449-SUM_CR_GMT_SemB_06_UC_DP100_864_003.jpg

Answers

1. The sum of the opposite angles of the quadrilateral ABCD that is inscribed in the circle, is 180°. Therefore, the sum of all the angles is 360°.

2. As you can see, m∠B=(2x-1)° and m∠D=(3x-59)° are opposite angles, then:

m∠B+m∠D=180°

3. When you substitute the values of m∠B and m∠D into m∠B+m∠D=180°, you obtain:

m∠B+m∠D=180°
(2x-1)+(3x-59)=180°

4. You must clear the "x", as below:

(2x-1)+(3x-59)=180°
5x-60=180
x=48°

5. Now, you can find the value of m∠A, m∠B and m∠D:

m∠A=2x+4
m∠A=2(48)+4
m∠A=100°

m∠B=2x-1
m∠B=2(48)-1
m∠B=95°

m∠D=3x-59
m∠D=3(48)-59
m∠D=85°

6. Therefore, the value of m∠C is:

m∠A+m∠B+m∠C+m∠D=360°
m∠C=360-m∠A-m∠B-m∠D
m∠C=360°-100°-95°-85°
m∠C=80°

What is the measure of angle C?

The answer is: 80°

Zach has 53 flowers to plant. he wants to plant them in groups of 10s and 1s. zach can plant 10 flowers in each flower box. He can plant 1 flower in each pot. Zach only wants to plant a group of ten flowers in each box. Is there any way that zach could plant all 53 flowers using boxes only? Explain your answer.

Answers

No, he can not use boxes only

Solution:

we are given that

Zach has 53 flowers to plant.

He wants to plant them in groups of 10s and 1s.

zach can plant 10 flowers in each flower box.

Zach only wants to plant a group of ten flowers in each box.

We have been asked to find Is there any way that zach could plant all 53 flowers using boxes only?

since zach can plant 10 flowers in each flower box. so in 5 boxes he can plant

50 flowers.

Now we have 3 left. These 3 can be planted in pot.

But he wants to use boxes only with 10 flowers in each box.

So its not possible to plant all 53 flowers using boxes only.

The enrollment in college a may be modeled by y = 0.051x + 0.470, and the enrollment in college b may be modeled by y = –0.041x + 1.850, where x is the number of years since 1990 and y is the enrollment in thousands. when will the two colleges have the same enrollment and what is that enrollment?

Answers

The first equation represents the enrollments of college A
The second equation represents the enrollments of college B
if you let two equation equal to each other, you can understand them as the enrollments of college A and college B at "x" year.

0.051x + 0.470 = -0.041x + 1.850
0.051x + 0.041x = 1.850 - 0.470
0.092x = 1.38
x = 1.38/0.092 = 15 years from 1990, 1990 + 15 = 2005
both equations represents the enrollments, but for specific the year of 2005, they have the same enrollments. You can either plug 2005 in the first or second equation, the answer will come out the same.
y = 0.051(2005) + 0.470 = 102.745 thousands of enrollments. It's awkward to say it this way, you can multiply 102.745 by 1000.
==> 102.725 * 1000 = 102725 enrollements
===================================================================
The year of 2005 college A and college B both have the same enrollments of 102725.

In year 2005, both the colleges have same enrollments and the total number of enrollments are 1235 students.

What is Two Variable linear Equation?

An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.

Here, given relation between enrollment year and total number of enrollment

y = 0.051x + 0.470 ..............(i)

y = -0.041x + 1.850 ................(ii)

On comapring eq. (i) and eq. (ii), we get

0.051x + 0.470 = -0.041x + 1.850

0.051x + 0.041x = 1.850 - 0.470

0.092x = 1.380

x = 1.380 / 0.092

x = 15

put the value of x in equation (i), we get

y = 1235

Thus, In year 2005, both the colleges have same enrollments and the total number of enrollments are 1235 students.

Rich is driving from Philadelphia to Pittsburgh at 70 mph and Michelle is driving from Pittsburgh to Philadelphia at 65 mph. If Philadelphia and Pittsburgh are 305 miles apart how long will it take rich and Michelle to meet?

Answers

Answer:

2 7/27 hours, about 2 hours 15 minutes, 33 seconds

Step-by-step explanation:

You want to know how long it takes for Rich and Michelle to meet if they start 305 miles apart and are driving toward each other. Rich is driving 70 mph, and Michelle is driving 65 mph.

Closing speed

The speed at which they are moving toward each other is ...

70 mph + 65 mph = 135 mph

Meeting time

That means they will reduce their separation distance to zero after ...

time = distance / speed

time = (305 mi)/(135 mi/h) = 2 7/27 h

It will take 2 7/27 hours, about 2.26 hours, for Rich and Michelle to meet.
