Answer:

(5x^2+2)(3x - 1)

Step-by-step explanation:

Factor 15x^3-5x^2 + 6x – 2 by grouping

15x^3 - 5x^2 + 6x - 2

In grouping method we group first two terms and last two terms

(15x^3 - 5x^2) + (6x - 2)

Take out GCF from each group

5x^2(3x - 1) + 2(3x - 1)

Now we factor out 3x-1

(5x^2+2)(3x - 1)

Below is the graph of y=b^x. Find b.
omeli [17]
Y = <span>b^x

when x = 1
y = b^1
y  = b

Therefore, the value of b is the same as the value of y when x =1
From the graph,
When x = 1, y = 0.5
Therefore, b = 0.5


To confirm this

From the graph,

When x = -1, y = 2
Since </span>y = b^x<span>
2 = </span>b^-1
2 = 1/b
2b = 1
b = 0.5

When x = -2, y = 4
Since y = b^x
4 = b^-2
4 = 1/(b^2)
b^2 = 1/4
b = √(1/4)
b = 1/2
b = 0.5

Therefore, it is conformed that b = 0.5

Can a remainder in a division problem equal the divisor
Rufina [12.5K]

Find the area of the blue shaded region. Round your answer to the nearest hundredth.
SSSSS [86.1K]

Answer:

173.01

Step-by-step explanation:

To area of a sector or portion of a circle is found using:

A = \frac{N}{360} \pi r^2

Substitute N = 50 and A = 27.93.

It becomes 27.93 = \frac{50}{360} \pi r^2\\27.93 = 0.139 \pi r^2\\200.94 = \pi r^2

The area of the entire circle is 200.94. The area of the blue part of the circle can be found by subtracting the red section from the entire circle.

200.94 - 27.93 = 173.01
