Answer:

An equation of the circle with centre (5,7) and radius 2 is [tex]\mathbf{(x-5)^2+(x-7)^2=4}[/tex]

Option A is correct.

Step-by-step explanation:

A circle in the xy-plane has centre (5,7) and radius 2. Which of the following is an equation of the circle.

The equation of circle is of form: [tex](x-h)^2+(x-k)^2=r^2[/tex] where (h,k) is centre and r is radius.

We have centre (5,7) so, we have h = 5 and k = 7

We have radius = 2 so, r = 2

Putting values in the equation and finding the required equation:

[tex](x-h)^2+(x-k)^2=r^2\\(x-5)^2+(x-7)^2=(2)^2\\(x-5)^2+(x-7)^2=4[/tex]

So,  an equation of the circle with centre (5,7) and radius 2 is [tex]\mathbf{(x-5)^2+(x-7)^2=4}[/tex]

Option A is correct.

Answers

Answer:

Width=22, Length=27, Area= 594

Step-by-step explanation:

Let the width if the rectangle be represented by x

If the length is 5 more than the width

Length =x+5

The perimeter is given by

2(x)+2(x+5)=98

2x+2x+10=98

4x=88

x=22

Width=22

Length=27

Area= 22*27=594

Angie wants to make a special cake for her family, but the recipe is in all metric measures. The recipe calls for 708 milliliters (ml) of milk. If 16 cups of milk = 3785.4 ml, how many cups of milk should Angie use for the cake? Round your answer to the nearest cup.

Answers

Answer:

theres some balls in my mouth

Step-by-step explanation:

Answer:

3 cups or 2.99254101 cups

Step-by-step explanation:

16 cups = 3785.4 mL

Convert 708 Milliliters to Cups

To calculate 708 Milliliters to the corresponding value in Cups, multiply the quantity in Milliliters by 0.0042267528198649 (conversion factor). In this case we should multiply 708 Milliliters by 0.0042267528198649 to get the equivalent result in Cups:

708 Milliliters x 0.0042267528198649 = 2.9925409964644 Cups

708 Milliliters is equivalent to 2.9925409964644 Cups.

How to convert from Milliliters to Cups

The conversion factor from Milliliters to Cups is 0.0042267528198649. To find out how many Milliliters in Cups, multiply by the conversion factor or use the Volume converter above. Seven hundred eight Milliliters is equivalent to two point nine nine three Cups.

Definition of Milliliter

A milliliter (also written "millilitre", SI symbol ml) is a non-SI metric system unit of volume which is commonly used as liquid unit. It is equal to 1/1000 liter, or one cubic centimeter, therefore, 1ml = 1/1000 L =1 cm3.

Definition of Cup

The cup is an English unit of volume, most commonly associated with cooking and serving sizes. It is traditionally equal to half a liquid pint in either US customary units or the British imperial system but is now separately defined in terms of the metric system at values between 1⁄5 and 1⁄4 of a liter. Because actual drinking cups may differ greatly from the size of this unit, standard measuring cups are usually used instead. In the United States, the customary cup is half of a liquid pint or 8 U.S. customary fluid ounces. One customary cup is equal to 236.5882365 millilitres.

The answer is 2.99254101 cups (rounded to the nearest cup it is 3 cups!)

Answer:

Step-by-step explanation:

-5x + y = 1

Subtract yy from both sides.

-5x=1-y

−5x=1−y

x=-\frac{1-y}{5}

x=−

1−y

-10x+2y=-2

Factor out the common term 22.

2(5x+y)=-2

2(5x+y)=−2

2 Divide both sides by 22.

5x+y=-1

5x+y=−1

3 Subtract yy from both sides.

5x=-1-y

5x=−1−y

4 Divide both sides by 55.

x=\frac{-1-y}{5}

Step-by-step explanation:

if f(a) means when x = a, the value of f(a) would be the evaluated value.

[tex]f(6) = ...[/tex]

That means when x = 6, the value of y would be... As shown in the graph. The value of y is - 1 when x = 6.

[tex] \boxed {f(6) = -1}[/tex]

From the graph, when x = 2, y =-4. Therefore

[tex] \boxed {f(2) = - 4}[/tex]

The last problem. f(x) is defined as function f or function of x which equal to y-term.

[tex]f(x) = y[/tex]

Therefore when f(x)= -4 or y = - 4. The value of x would be

[tex]f(x) = - 4 \\ \boxed {x = 2,4,8, 10}[/tex]

Note that y = b where b is a constant will be a horizontal line graph. The line intercepts the graph of polynomial 4 points.

Two students are reading a book. Keith reads 6 pages a day. Tameka reads 5 pages a day, but he starts sooner and has already read 15 pages. Write a system of equations to represent the situation, using d for days and p for pages.

Answers

Answer:

P = 6d ; P = 5d + 15

Step-by-step explanation:

Given that :

Keith = 6 pages per day

Tameka = 5 pages per day

Tameka has already read 15 pages

If d = Number of days ; p = pages read

Keith :

Pages read, p = pages read per day * Number of days, d

P = 6d

Tameka :

Pages read, p = (pages read per day * Number of days, d) + pages read already

P = 5d + 15

The system of equations to represent the number of pages read per day by Keith and Tameka, using d for days and p for pages are,

[tex]\\P=6d[/tex]

[tex]P=5d+15[/tex]

What is the system of equation?

A system of equation is the set of equation in which the finite set of equation is present for which the common solution is sought.

Two students are reading a book.  Keith reads 6 pages a day. Equation for Keith, where d for days and p for pages can be given as,

[tex]P=6\times d\\P=6d[/tex]

Tameka reads 5 pages a day, but he starts sooner and has already read 15 pages. The equation for Tameka, where d for days and p for pages, can be given as,

[tex]P=5\times d+15\\P=5d+15[/tex]

Hence, the system of equations to represent the number of pages read per day by Keith and Tameka, using d for days and p for pages are,

[tex]\\P=6d[/tex]

Answers

Answer:

$8 ; 66 cents

Step-by-step explanation:

Worth of penny, dimes and Nickel in cents and dollars

Nickel, n = 5 cents = $0.05

Dimes, d = 10 cent = $0.1

Penny, p = 1 cent = $0.01

386(0.01) + 58(0.05) + 19(0.1)

$3.86 + $2.9 + $1.9

= $8.66

Katie invested a total of ​$4000​, part at 2​% simple interest and part at 3​% simple interest. At the end of 1​ year, the investments had earned ​$90 interest. How much was invested at each​ rate?

Answers

Answer:

$3000

$1000

Step-by-step explanation:

the formula for simple interest = principal x time x interest rate

let the amount invested in the 2% investment be a

let the amount invested in the 3% investment be (4000 - a)

(a x 0.02 x 1) + ([4000 - a] x 0.03 x 1) = $90

0.02a + 120 - 0.03a = 90

Collect like terms and solve for a

0.01a = 30

a = $3000

The amount invested in the 3% investment be (4000 - a)  = $4000 - $3000 = $1000
