Answer:

Step-by-step explanation:

f"(x)=2

integrating

f'(x)=2x+c

f'(1)=2+c=4

c=4-2=2

f'(x)=2x+2

integrating

f(x)=2x^2/2+2x+a

f(x)=x^2+2x+a

f(2)=-2

(2)^2+2(2)+a=-2

4+4+a=-2

a=-2-8=-10

f(x)=x^2+2x-10

Answer:

1)An angle bisector is basically the division of an angle into two equal parts, so you should just draw a line in the middle after you found the angles using the compass

2) parallel lines is a pair of lines that never intersect, and are always the same distance apart. you should use the compass to draw a 90-degree angle at the end of the line XY, and use the straightedge to draw a line that is parallel to the line XY.

Answer:

see attached diagram

Step-by-step explanation:

Angle Bisector

The angle bisector bisects the angle into two equal angles.

Measure the angle EDF (I've measured this as 115°)

Divide this by 2:  115 ÷ 2 = 57.5°

Measure an angle of 57.5° from point D on the line DF and draw a line.

Parallel lines

Measure two lines of equal length from points X and Y at an angle of 90° to the line XY.  Join the points for the parallel line.

The angle bisector and parallel line are shown in red on the attached diagram.

Answer:

in the space of x we'll equate it to 5-y

2(5-y)+3y=12

10-2y+3y=12

-2y+3y=12-10

y=2

subt y into first equation (x=5-y)

x=5-2

Step-by-step explanation:

»f(x) = 7x² - 3x + 7

»f(2) = 7(2)² - 3(2) + 7

»f(2) = 7(4) - 6 + 7

»f(2) = 28 - 6 + 7

»f(2) = 29

Answer:

∠ ACD = 130°

Step-by-step explanation:

∠ ABC = 180° - 120° = 60° ( adjacent angles on a straight line )

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ ACD is an exterior angle of the triangle , then

∠ ACD = 70° + 60° = 130°

The length of side MP in circle Q is 4.36.

A circle is the locus of a point such that its distance from a fixed point known as the center is always constant.

From the circle:

∠OMP = 90° (angle in a semicircle)

Hence using Pythagoras theorem:

OP² = MP² + MO²

10² = 9² + MP²

MP = 4.36

The length of side MP in circle Q is 4.36.

The width of the rectangular field is 50[tex]\sqrt{2}[/tex] yards.

Step-by-step explanation:

Use the Pythagorean Theorem to solve this problem: a^2+b^2=c^2

a^2 + 115^2 = 135^2

a^2 + 13225 = 18225

(Subtract both sides by 13225)

a^2 = 5000

Take the square root of both sides.

Answer:

24 is gonna be the awnser

Answer:

Step-by-step explanation:

x² - 7x - 18 = 0

Product = -18

Sum = -7

Factors = 2 , (-9)    {2*(-9) = -18  & 2 +(-9) = -7}

x²  + 2x - 9x - 18 = 0

x(x + 2) - 9(x + 2) = 0

(x +2)(x - 9)= 0

x + 2 = 0    ; x - 9 = 0

   x = -2     ; x  = 9

x = -2 , 9

Based on the price that Robin bought the watch and the price he sells it, his percentage loss is 30%.

This can be found by the formula:

= (Selling price - Purchase price) / Purchase price x 100%

Solving gives:

= (56 - 80) / 80 x 100%

= 24 / 80 x 100%

= 30%

In conclusion, Robin suffered a 30% loss.

The monthly payment for a one-year loan = $1,081.00

The higher the period of time, the lesser the monthly payment of a loan.

Claire needs to borrow $12,000 from a local bank with an interest of 8.1% which is,

8.1/100 × $12,000 =$972

This means after one year she will pay back;

$12,000 + $972 = $12,972

Therefore, monthly payment for a year loan = 12972/12

= $1,081.00
