We know that

When we have

f(x)=ax^2 +bx+c

Here ,

a is the leading coefficient

c is the constant term

so, we can compare it with

f(x)=5x^2-7x+6

so, we get

a=5,c=6

so,

leading coefficient is 5

constant term is 6......................Answer

soldi70 [24.7K]

Answer: Stacey now bakes 36 cinnamon bagels.

Step-by-step explanation:

Given:  Each morning, Stacey makes 20 cinnamon bagels.

She has increased the number she bakes each morning by 80%.

Number of cinnamon bagels Stacey bake = 20+80% of  20

= 20+ (0.80)x 20           [To remove % , divide number by 100, So 80%=0.08]

= 20+16   [(0.80)x 20=16 ]

= 36

Hence, Stacey now bakes 36 cinnamon bagels.

Find the arc measure of AB.<br> The measure of arc AB = ______ degrees
mariarad [96]
The picture is difficult to read, but it looks like
  ∠ADB = 2x²
  ∠ACB = 10x
These two angles have equal measure, so you have
  2x² = 10x
  2x(x -5) = 0 . . . . . subtract 10x and factor
  x = 0, or x = 5

The measure of arc AB is twice the measure of either inscribed angle, so would be
  arc AB = 2×10x
  = 2×10×5
  = 100 . . . . . degrees

Arc AB is 100°.
