Answer:

I think its 15^-7

Step-by-step explanation:

you can forget about the one and just look at the 15 and 7 which you get 15^-7

The fraction (1/15)⁷ can be written as 15⁻⁷ after using the properties of the integer exponent.

In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.

It is given that:

The number expression is:

= (1/15)⁷

As we know, from the definition of the integer exponent;  integer exponents are exponents that should be integers. It may be a positive or negative number.

After using the properties of the integer exponent:

= (15⁻¹)⁷

= 15⁻⁷

Thus, the fraction (1/15)⁷ can be written as 15⁻⁷ after using the properties of the integer exponent.

Answer: The length of the fence will be 150 feet

Step-by-step explanation:

The question is asking you to find the hypotenuse of a rectangle with a length of 120 feet and a width of 90 feet. To find the hypotenuse we will need to use the formula   a^2 + b^2 = c^2

120 feet will be a

90 feet will be for b  

this is because a and b are the two legs of the rectangle.

120^2 + 90^2 = c^2

14400 + 8100 = c^2

22500 = c^2

   c =√22500

 c= 150

Answer:

y = 9.38

Step-by-step explanation:

8/x = x/3

x^2 = 24 = 2(sq rt 6)

using the pythagorean theorem:

x^2+8^2 = y^2

y^2 = 24+64 = 88

y = 9.38

The new c term be 49 for completing the square.

x² - 14x + 49

= x² - 2 * x * 7 + 7²

= ( x - 7) ²

Hope it will help :)

Answer:

49

Step-by-step explanation:

What two numbers add to the middle term and multiply to the last term? 49 doesnt fit in to 14 at all so we know that one of the factors is 7. since the middle term is -14, you would add -7 to -7 to get that. so we know the factors of the middle term are -7 and -7, so all you have to do is multiply them together. It would be positive 49.

Answer:

Step-by-step explanation:

Length (L)= 2x - 3 cm

Breadth (b) = x + 7 cm

Area of the rectangle

= L * b

= ( 2x - 3)(x+ 7)

= 2x(x + 7) - 3(x + 7)

= 2x² + 14x  - 3x - 21

=( 2x² + 11x - 21) cm²

Answer:

[tex]2x^{2}[/tex] + 11x -21 [tex]cm^{2}[/tex]

Step-by-step explanation:

Area of a rectangle = Length × Width

= (2x-3)(x+7)

Multiply 2x with x, 2x with +7, -3 with x and -3 with +7

= [tex]2x^{2}[/tex] + 14x - 3x - 21

= [tex]2x^{2}[/tex] + 11x -21 [tex]cm^{2}[/tex]

B: Ellipse

Step-by-step explanation:

Just put in the equation on desmos. An ellipse will pop-up

The conic section is represented by the following equation –5x^2 + 9xy + 5y^2 + 6x – 4y + 11 = 0 is  circle.

We have given that the equation of the equation is,

–5x^2 + 9xy + 5y^2 + 6x – 4y + 11 = 0

The general formula of the circle is

[tex]ax^2+2xy+by^2+2fx+2gy+c=0[/tex]

Compare the given equation with the general formula of the circle so we get the equation of the circle

Therefore the equation of the circle is  –5^+ 9xy + 5y^2 + 6x – 4y + 11 = 0

Answer:

5,240 literate

1310 illiterate

Step-by-step explanation:

-ratio of literate : illiterate is 1:4

-add the numbers in the ratio (4+1=5)

-divide total population by 5 (6,550/5= 1,310)

-multiply the outcome by 4 to find the number of literate people (1,310*4=5,240 people)

-subtract the number of literate people from total population to find number of illiterate people (6,550-5,240= 1,310 people).

Answer:

There is not an actual question here, so i will answer this in a general way.

The initial height of the tree is 4 ft.

We know that every 5 weeks, the tree grows 2 ft

Then the rate at which the tree grows can be calculated as:

R = (how much it grows)/(in how much time)

Then:

R = (2 ft)/(5 weeks) = 0.4 ft/week

This means that the tree grows 0.4 feet per week.

Then we can write the equation:

H(w) = 4ft + (0.4ft/week)*w

Where w is the number of weeks since John planted the tree.

So if we want to know the height of the tree in a particular week, like week 3, we just need to replace w by 3 weeks in the above equation:

H(3 weeks) = 4ft + (0.4 ft/week)*(3 weeks)

                   = 4ft + 1.2 ft = 5.2 ft

Answer:

  a) 22

  b) 18

Step-by-step explanation:

a) In order for 198k to be a perfect square, all of its integer factors must be squares. 3² is already a factor. To make the other factors be squares, need to multiply by 2 and 11. That is, k = 2×11 = 22. Then we will have ...

  198k = 2×3²×11 × (2×11) = 2²×3²×11² = (2×3×11)²

  k = 22

__

b) The factors that are different in the two numbers are 11 and 5. The factors that are the same are 2×3² = 18.

  18 is the greatest common factor of 198 and 90
