Let's assume point (5,1) to be C

according to the picture we know AC= 3 and BC=4

Applying pythagorean theorem: a^2+b^2=c^2

(AC)^2+(BC)^2=(AB)^2

3^2+4^2=(AB)^2

9+16= (AB)^2

AB^2=25

AB=5

Answer:

[tex]x = 12[/tex]

Step-by-step explanation:

1) Set up an equation that involves all of the values; the price and kg of each duck and chicken equating to 206.40.

[tex]8.50(x) + 3.60(2x + 5) = 206.40[/tex]

[tex]8.50x + 7.2x + 18 = 206.40[/tex]

2) Solve it.

[tex]15.7x + 18 = 206.40[/tex]

[tex]15.7x = 206.40 - 18[/tex]

[tex]15.7x = 188.4[/tex]

[tex]x = \frac{188.4}{15.7}[/tex]

[tex]x = 12[/tex]

Write both fractions in terms of a common denominator. In this case, it's the least common multiple of 6 and 12, which is 12 = 2•6. So multiply the first fraction by 2/2, then simplify:

[tex]\dfrac46 - \dfrac3{12} = \left(\dfrac22\times\dfrac46\right) - \dfrac3{12} = \dfrac{2\times4}{2\times6}-\dfrac3{12} = \dfrac8{12}-\dfrac3{12} = \dfrac{8-3}{12} = \boxed{\dfrac5{12}}[/tex]

Answer:

x = 39

Step-by-step explanation:

Secant and tangent line from a point outside the cirlcle,

(length of th tangent)² = length of the secant * external segment

                   26²          =  (13 + x) * 13

               [tex]\sf (13 +x)*13 = 26 *26\\[/tex]

                           [tex]\sf 13 + x =\dfrac{26*26}{13}[/tex]

                           13 + x   = 2* 26

                           13  + x = 52

                                   x = 52 - 13

                                  x = 39

Answer:

22 and 7

Step-by-step explanation:

Let x and y be the two numbers we are looking for:

The statement “their sum is 29” means x + y = 29

The statement “their difference is 15” means x - y = 15

we get this system:

x + y = 29 (1)

x - y = 15   (2)

Let’s solve it :

(1) + (2) ⇒ x + y + x - y = 29 + 15 ⇒ 2x = 44 ⇒ x = 44/2 = 22

Now we replace x by 22 in equation (1) :

22 + y = 29  ⇒ y = 29 - 22 = 7

Answer:

18.8

Step-by-step explanation:

First find the area of the rectangle, which is 4x3 (base x height) the area of the rectangle is 12.

We are given the radius as 2 for the quarter circles, and 2 quarter circles form 1 semicircle, so really we can solve for the area of one semi circle using the formula ( (pi*radius²)/2 ). Plug in the values and you should get 6.28.

Next, you add the area of the figures so 12+6.8 which is equal to 18.8.

Answer:

32

Step-by-step explanation:

Triangle angle = 180

First we add!

58 + 90 + c = 180

148 + c = 180

Now we subtract!

180 - 148 = c

32 = c

The value of the function when x = 2 will be 9. The value is obtained by putting the value 2 in the place of x.

A connection between independent variables and the dependent variable.is defined by the function. Functions help to represent graphs and equations.

The given function in the problem is;

[tex]\rm f(x) = 2x^2 - 3x + 7[/tex]

On putting x =2 we get;

[tex]\rm f(2) = 2(2)^2 - 3(2) + 7 \\\\\ f(2) = 2(4) - 3(2) + 7 \\\\ f(2) = 8 - 6 + 7 \\\\ f(2) = 9[/tex]

Hence the value of the function when x = 2 will be 9.

Answer:

45.2pi inches

Step-by-step explanation:

C=2×pi×r

since the answers already have pi we don't need to multiply it

C=2×22.6 = 45.2pi inches

Answer:

A. 22.6π

Step-by-step explanation:

Given:

22.6 inches across = diameter

What we need to find is how much ribbon do we need, so we use the formula:

C = 2πr

C = Circumference

r = radius = half diameter

Since we know the diameter, we do half of it to get the radius

22.6 ÷ 2 = 11.3

radius = 11

Now we substitute this into the formula:

C = 2πr

Substitute radius into formula

C = 2π(11.3)

Multiply 2 and 11.3

C = 22.6π

ok done. Thank to me >:3

the question requires:

the time t required.

the equation of the inverse variation.

how do find t:

first we determine how much the tank holds by multiplying 120 by 40.

the tank holds 4800 gallons.

so now to find t we can use the formula v = d/t where d is the 4800 gallons.

so: t = d/v

t = 24 minutes

now for the equation of the inverse variation.

we can say that the equation is t = d/v since t and v are inversely proportional.

note that v and t stand for velocity and time respectively.

make sure to ask if you need any further guidance!!

Answer:

t = 24

Answer:

x=3

Step-by-step explanation:

The equation is written in the form ax2+bx+c. As you can see, a=1, b=-6 and c=2. The axis of symmetry is worked out by x=−b2a.

−(−6)2(1) = 62=3

Substituted this value of x back into the equation to find the y coordinate.

y=(3)2−6(3)+2

y=9−18+2

y=−7q

So the vertex of the line is at (3,-7)

The $5000 will be taxable amount at 10% of Latonya's salary, and $14000 will be taxable amount at 28% of Latonya's salary.

It is defined as the tax rate applied on the solely earned money by a single entity.

Latonya salary per year = $50,000

If Latonya's salary will be taxed at the 10% rate, then she needs to pay tax:

[tex]= $50,000\times10\%[/tex]

[tex]=50000\times \frac{10}{100}[/tex]

[tex]= \$ 5000[/tex]

If Latonya's salary will be taxed at the 28% rate, then she needs to pay tax:

[tex]= \$50,000\times28\%[/tex]

[tex]=50000\times \frac{28}{100}[/tex]

[tex]= \$14000[/tex]

Thus, the $5000 will be taxable amount at 10% of Latonya's salary, and $14000 will be taxable amount at 28% of Latonya's salary.
