Two segments  that are tangent to a circle from the same external point are of equal length.
9)   2x²=8x
2x²-8x=0
x(2x-8)=0
x=0,
2x-8=0
x=4  can be
2*4²=8*4=32

10)  y=y²/7
y²/7- y=0
y(y/7 -1)=0
y=0,
y/7 - 1=0
y/7=1 
y=7 can be
y=y²/7= 7

a car travels along a straight road heading east for one hour, then traveling for 30 minutes on another road that leads northeas
My name is Ann [436]

Answer:

55.96 miles

Step-by-step explanation:

Distance = Speed X time

Car first moved east for 1 hr , distance = 40 x 1 = 40 miles

Car then moved north-east for 30 min, distance = 40 x 0.5 = 20 miles

From trigonometry,

sin 45 = \frac{y}{20} ; y = 20 sin 45 ; y= 14.14 miles

cos 45 = \frac{x}{20} ; x = 20 cos 45 ; x = 14.14 miles

using Pythagoras theorem;

z^{2} = y^{2} + (40+x)^{2}

    = 14.14^{2} + (40+14.14)^{2}

     = 3131.08

z^{2} = \sqrt{3131.08}

z = 55.96 miles

While mining, John found a large metal bar that contained 15 pounds of zinc. John also determined that the bar was 60% zinc. Wha
finlep [7]

Answer:

The total weight of the metal bar in pounds is 25 pounds

Step-by-step explanation:

Now, we have a metal bar which has a content of 60% zinc corresponding to 15 pounds.

Mathematically, let’s say the total weight of the metal composite is x pounds. It is 60% of this that is 15 pounds which is the content of the zinc

Mathematically;

60/100 * x = 15

60x = 15 * 100

60x = 1500

x = 1500/60

x = 25 pounds
