O A. x = 0 only
O B. X = 7 only
O c. x = 0 and x = -7
O D. x = 0 and x = 7

Answers

Answer 1

Answer:

x=0   x=7

Step-by-step explanation:

A(x) = x(x-7)

Set equal to zero

x(x-7) =0

Using the zero product property

x=0     x-7 =0

A rectangular yard is fenced in using 319 feet of custom fence Your friends really like the fence and decide to fence in their yard using the same fence.
Their yard is similar but has a scale factor of 8/5 times the size of
yours, how much fence to the nearest foot, will they have to purchase?

A) about 321 feet
B) about 510 feet
C) about 542 feet
D) about 199 feet​

Answers

We have been given that a rectangular yard is fenced in using 319 feet of custom fence Your friends really like the fence and decide to fence in their yard using the same fence.  Their yard is similar but has a scale factor of 8/5 times the size of  yours.

We are asked to find the length of fence that your friends should purchase.

Since the size of your friend's yard is [tex]\frac{8}{5}[/tex] times your yard, so your friend should purchase [tex]\frac{8}{5}[/tex] times the 319 feet.

[tex]\text{Length of fence your friend should purchase}=\frac{8}{5}\times 319\text{ ft}[/tex]

[tex]\text{Length of fence your friend should purchase}=8\times 63.8\text{ ft}[/tex]

[tex]\text{Length of fence your friend should purchase}=510.4\text{ ft}[/tex]

Upon rounding our answer to nearest foot, we will get:

[tex]\text{Length of fence your friend should purchase}\approx 510\text{ ft}[/tex]

Therefore, your friends should purchase 510 feet of fence and option C is the correct choice.

The sum of the squares of two consecutive positive odd integers is 202. Find the numbers. Please use a let statement and algebraic solution. thanks! :)

Answers

Answer:

9 and 11

Step-by-step explanation:

The sum of the squares of two consecutive positive odd integers is 202.

Let first number be x and other number is (x+2).

According to question,

[tex]x^2+(x+2)^2=202\\\\x^2+x^2+4+4x=202\\\\2x^2+4x+4=202\\\\2x^2+4x-198=0[/tex]

It is a quadratic equation. The solution of a quadratic equation is given by :

[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac} }{2a}[/tex]

We have, a = 2, b = 4 and c = -198

So,

[tex]x=\dfrac{-b+ \sqrt{b^2-4ac} }{2a}, \dfrac{-b- \sqrt{b^2-4ac} }{2a}\\\\x=\dfrac{-4+ \sqrt{4^2-4\times 2\times (-198)} }{2(2)}, \dfrac{-b- \sqrt{b^2-4ac} }{2a}\\\\x=9, -11[/tex]

So, first positive odd integer is 9 and second one is (9+2)=11

PIZZA - frequency =3 angle = a
CURRY - frequency=12 angle =b
FISH AND CHIPS- frequency =7 angle =c
KABAB-frequency =3 angle = d
OTHER-frequency=15 angle = e

Answers

Answer:

Pizza: 27°

Curry: 108°

Fish and Chips: 63°

Kabab: 27°

Other: 135°

Step-by-step explanation:

Frequency 40 = 360°

Pizza (3) = [tex]\frac{3}{40}[/tex] * 360° = 27°

Curry (12) = [tex]\frac{12}{40}[/tex] * 360° = 108°

Fish and Chips (7) = [tex]\frac{7}{40}[/tex] * 360° = 63°

Kabab (3) = [tex]\frac{3}{40}[/tex] * 360° = 27°

Other (15) = [tex]\frac{15}{40}[/tex] * 360° = 135°

27 + 108 + 63 + 27 + 135 = 360

Use vertex form to write the equation of the parabola.

Answers

Answer:

y = - 2(x - 2)² - 3

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k) = (2, - 3) , thus

y = a(x - 2)² - 3

To find a substitute (1, - 5) a point on the curve into the equation

- 5 = a(1 - 2)² - 3

- 5 = a - 3 ⇒ a = - 5 + 3 = - 2

y = - 2(x - 2)² - 3 ← equation in vertex form

Answers

Answer: 80

Step-by-step explanation:

Sin x = cos (90-x)

Like sin 30 = cos (90-30) =cos 60

So

90-x=90-80

Then

X=80

Verify your solution by finding the sum of the angles of sin and cos, it will be 90

Answer:

Step-by-step explanation:

Sin Ф = Cos (90 - Ф)

Comparing with this

Sin 80 = Cos (90 - 80) = Cos 10

So, x = 80

Find the area of the circle that contains the sector described below. Round to the nearest tenth, if necessary.

One sector has an area of 210 square centimeters and an arc measure of 30°.


_____________ cm squared

Answers

Answer:

The area of the circle is 2520 cm²

Step-by-step explanation:

The area of an arc is given by the following formula:

arc area = pi*r²(angle/360)

In this case we have the area and the angle and we want to find r, so we have:

210 = pi*r²*(30/360)

210 = pi*r²*(1/12)

210*12 = pi*r²

pi*r² = 210*12

r² = 2520/pi

r = sqrt(2520/pi)

r = 28.3221

The area of the circle that has this arc is given by:

area = pi*r²

area = pi*(28.3221)² = 2520 cm²

Step-by-step explanation:

There are 1,000 milliliters in a liter. So, if we had 1 liter, we would have 1*1,000=1,000 milliliters.

When you change the 1 liter to 34, we can just substitute 34 for 1. So, the answer is 34*1,000=34,000 milliliters, or D

Write down a mixed number between 3 3/11 and 3 2/5

Answers

Answer:

3 7/23

Step-by-step explanation:

Hope this helps.

Mixed fractions are a fraction that represents their quotient and remainder. It is a type of fraction in which the whole number part and fractional part is present.

At first, we have to find the common denominator LCD [tex]=11*5=55[/tex];

Now, [tex]\frac{36}{11}=\frac{180}{55}[/tex]  and [tex]\frac{17}{5}=\frac{187}{55}[/tex]

So, from above we get;

[tex]\frac{181}{55} , \frac{182}{55},\frac{183}{55}, \frac{184}{55} ,\frac{185}{55} ,\frac{186}{55}[/tex] as mixed fractions between given mixed fractions.

Again, we will multiply both denominator and numerator by 2, and we get;

[tex]\frac{180}{55}=\frac{360}{110}[/tex]  and [tex]\frac{187}{55} =\frac{374}{110}[/tex]

So, repeating the same step, we get;

[tex]\frac{361}{110},\frac{362}{110} ,\frac{363}{110} ,\frac{364}{110} ,\frac{365}{110},\frac{366}{110} ,\frac{367}{110} ,\frac{368}{110},\frac{369}{110} ,\frac{370}{110} ,\frac{371}{110} ,\frac{372}{110} ,\frac{373}{110}[/tex] are mixed fractions

between given mixed fractions.

What is a mixed fraction?

A fraction represented with its quotient and remainder is a mixed fraction. For example, 2 1/3 is a mixed fraction, where 2 is the quotient, 1 is the remainder. So, a mixed fraction is a combination of a whole number and a proper fraction

What is improper and mixed fractions?

A mixed fraction is one whose value is always greater than 1 and it has a whole number part and a proper fraction. For example, 325 3 2 5 is a mixed number. An improper fraction is one in which the numerator is always greater than or equal to the denominator.

One of your friends has mined gas-station data off the web and has plotted every gas station along your route along with the price of gas at that gas station. Specically they have created a list of n+1 gas station prices from closest to furthest and a list of n distances between two adjacent gas stations. Tacoma is gas station number 0 and Tijuana is gas station number n. For convenience they have converted the cost of gas into price per mile traveled in your car. In addition the distance in miles between two adjacent gas-stations has also been calculated.
