find the x-intercepts, use the zero product property, r(r+7)=0

Answer:

The correct answer is [tex]11.45 cm. ^2[/tex]

Step-by-step explanation:

I just got it correct.

The approximate area of the shaded sector in the circle shown is,

⇒ 11.45 cm²

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

We have to given that;

A circle is shown in figure with diameter 5.4 cm.

Hence, Radius of circle = 5.4 / 2 = 2.7 cm

Since, Area of circle = πr²

Hence, We get;

Area of circle = πr²

Area of circle = 3.14 × 2.7²

Area of circle = 22.89 cm²

Thus, Area of shaded region of the circle is,

⇒ 22.89 cm²

⇒ 22.89/2 cm²

⇒ 11.45 cm²

Thus, The approximate area of the shaded sector in the circle shown is,

⇒ 11.45 cm²

Answer:

2y - 3x = -15

Step-by-step explanation:

Slope of the line 4x + 6y = 1 is as shown below;

Rewrite in slope intercept form;

6y = -4x+1

y = -4x/6 + 1/6

y = -2x/3 + 1/6

mx = -2/3x

m = -2/3

The slope of the line perpendicular M = -1/(-2/3)

M = 3/2

Get the x and y intercept of 2x+3y = 18

x intercept occurs when y  = 0

2x + 0 = 18

x= 18/2

x = 9

y intercept occurs when x  = 0

0 + 3y = 18

3y= 18

y = 18/3

y = 6

The line passes through the point (9,6)

Write the equation in point slope form

y - y0 = m(x-x0)

y - 6  = 3/2(x-9)

2(y-6) = 3(x-9)

2y - 12 = 3x - 27

2y - 3x = -27 + 12

2y - 3x = -15

This gives the required equation

Answer:

-3 is less than -5

Step-by-step explanation:

the bigger the negative number is, the less it has a great amount of value.

-3>-5 is correct because -3 is greater than -5

-5 is to the left of -3 on the number line is true

-3 is to the right of -5 on the number line is true as well

Answer:

4

Step-by-step explanation:

First we should simplify the formula. The simplified formula would be 1/3n+2/3. We then substitute 10 for n. (10/3)+2/3= 12/3=4.

Answer:

1: 1.5 would be 1.72 and 2 would also be 1.72.

2: Draw points at (0,1.15) (1, 1.72) (2, 2.29) (3, 2.86) Flatline Connections

Step-by-step explanation:

If Im reading it right you take 1.5 ounces and plug it into the function (it would be between 1 and 2) it would spit out 1.72 (which I'm assuming is the postage)  

It will cost

(i) $1.72 if weight is 1.5 ounces,to send a letter.

(ii)$1.72 if weight is 2 ounces, to send a letter.

first, let us find a relation between postage(dollars) and weight(ounces)

this is an equation of a straight line passing through (0,1.5) and (2,0).

y=mx+c

[tex]P(w)=\frac{1.5-0}{0-2} x + c\\\\P(w)=-0.75x+c\\\\[/tex]

since it passes through (2,0) it will satisfy the equation

therefore, c =1.5

the equation will be: [tex]P(w)=-0.75w+1.5[/tex]

after we merge both the relations, we find a single relation between cost and weight

since the cost value is 1.72 in 1 <w [tex]\leq[/tex]2

if weight is 1.5 ounces it is clearly $1.72

if weight is 2 ounces it is clearly $1.72

therefore, it will cost

(i) $1.72 if weight is 1.5 ounces,to send a letter.

(ii)$1.72 if weight is 2 ounces, to send a letter.

Answer:

FV= $123,879.85

Step-by-step explanation:

Giving the following information:

Montlhy deposit (A)= $100

Monthly interest rate (i)= 0.09/12= 0.0075

Number of periods (n)= 12*26= 312 months

To calculate the future value, we need to use the following formula:

FV= {A*[(1+i)^n-1]}/i

A= monthly deposit

FV= {100*[(1.0075^312) - 1]} / 0.0075

FV= $123,879.85

Option B

Step-by-step explanation:

Given function is,

p(x) = x²- (2√2)x + 1

We have to find the value of p(2√2).

By substituting the value x = 2√2

p(2√2) = (2√2)² - (2√2)(2√2) + 1

           = 8 - (2√2)² + 1

           = 9 - 8

           = 1

Therefore, Option B will be the correct option.

Answer:

x = 120

y = 30

Step-by-step explanation:

Given that RST is equilateral, each of its interior angles will be 60 degrees

Looking at x, it lies on a starting line with one of the interior angles of RST

The sum of angles on a straight line is 180

Thus;

x + 60 = 180

x = 180-60

x= 120

Looking at triangle RSU, the markings indicates that we have an isosceles triangle

For an isosceles triangle, the base angles are equal in value

This means that SRU is also y

Mathematically, the sum of angles in a triangle is 180

Hence;

x + y + y = 180

x + 2y = 180

120 + 2y= 180

2y = 180-120

2y = 60

y = 60/2

y = 30

Step-by-step explanation:

Your teacher probably told you the necessary fundamentals of monomials. So, I'll just teach you the things needed for this particular question.

10m^3/(10m)(m)

First, in the denominator, since that m are being multiplied and they are the same terms, their exponents add:

10m * m

10m^1 * m^1

1 + 1 = 2

10m^2

Then, since that m are now being divided, their exponents subtract:

10m^3 / 10m^2

3 - 2 = 1

10m^1

10m
