Tangent line i think please help me find x

Alex

Answer:

x= 6.5 cm

Step-by-step explanation:

When a tangent line touches the circle, it forms a right angle triangle at that point

Apply the Pythagorean relationship in this case

Given that the height is = 20.2 cm = b

The hypotenuse is = c= x+14.7 cm

General formulae is;

a² +b² =c²

x² + 20.2² =( x+ 14.7)²

x² + 408.04= x² +14.7x+14.7x+216.09

x² + 408.04= x² + 29.4 x +216.09.........................collect like terms

x²-x² + 408.04-216.09= 29.4x

191.95= 29.4x-------------------------------divide by 29.4 t0 get x

191.95/29.4 =x

x=6.5 cm

The functions f (x) = 1/2x-3 and g(x) = -2x+ 2 intersect<br> at x = -2. True or false?

Norma-Jean [14]

9514 1404 393

Answer:

False

Step-by-step explanation:

f(-2) = (1/2)(-2) -3 = -1 -3 = -4

g(-2) = -2(-2) +2 = 4 +2 = 6

The function values are not the same at x=-2, so the graphs do not intersect there.

__

The graphs intersect at x=2.

What is the difference between

ankoles [38]

we are given

$\sum _{n=0}^4\:\left(1+3n\right)$

we can find it's sum

$\sum _{n=0}^4\:\left(1+3n\right)=(1+3*0)+(1+3*1)+(1+3*2)+(1+3*3)+(1+3*4)$

$\sum _{n=0}^4\:\left(1+3n\right)=35$

now, we can find second sum

$\sum _{i=2}^6\:\left(3i-5\right)=(3*2-5)+(3*3-5)+(3*4-5)+(3*5-5) + (3*6-5)$

$\sum _{i=2}^6\:\left(3i-5\right)=35$

so, we can see that

both sums are 35

so, their difference will be 0
