AB and BC are two equal chords of a circle of length 2√5 cm each. If radius of the circle is 5 cm, find the length (in cm) of the chord AC.

Answer:

4x^2+17x+15

Step-by-step explanation:

(4x-3)(x+5)

= 4x(x+5) -3(x+5)

= 4x^2+ 20x -3x + 15

= 4x^2 + 17x + 15

the range is

[tex]( - \infty \: \infty )[/tex]

Answer:

4(x-5)+(3x+15)-5x

4x-20+3x-20+15=0

collect like terms

4x-5x+3x-20+15=0

2x-5=0

2x÷2=5÷2

x=5÷2

The value of 'r' in the expression 24(34 + r) = 1200 is 16.

There are three types of basic arithmetic laws of operation.

Commutative law for addition and multiplication states,

a + b = b + a.

a×b = b×a.

Distributive law states,

a(b ± c) = ab ± ac.

Associative law states,

a + (b + c) = (a + b) + c.

Given, An expression 24(34 + r) = 1200.

First, we'll distribute LHS,

24×34 + 24×r = 1200.

816 + 24r = 1200.

24r = 1200 - 816.

24r = 384.

r = 384/24.

r = 16.

Answer:

1. B

2. D

Step-by-step explanation:

1. Lon's cost would be the $12 per basket times how many baskets he sells, in this case b plus the cost of the table. Lon's expression is 12b + 75

2. He needs a profit and the only way he could make that profit is if he sells more than 12.

20b > 12b + 75

20 (12) > 12 (12) + 75

240 > 140 + 75

240 > 215

Answer:

4/7 > x > -11/7

Step-by-step explanation:

First, add -4/3 to all parts

then divide all parts by -7/3

so, We need to separate it into two inequalities

[tex] \frac{4 - 7x}{3} > 0[/tex]

[tex] \frac{4 - 7x}{3} < 5[/tex]

then we solve for x,

[tex] \frac{4 - 7x}{3} > 0 = x < \frac{4}{7} [/tex]

[tex] \frac{4 - 7x}{3} < 5 = x > - \frac{11}{7} [/tex]

so we ended up like this

[tex]x = ( - \frac{11}{7} \frac{4}{7})[/tex]

Answer:

  y = 2x + 8

Step-by-step explanation:

You can see that the line crosses the y-intercept at 8 which is point (0, 8). From that y-intercept point you rise 2 then run 1 to get to point (2, 12), this rise over run is your slope 2/1 or simply 2.

y = mx + b

m is your slope

b is your y-intercept

y = 2x + 8
