Answer:

A(x) = 6x² + 26x

Step-by-step explanation:

A(x) = 4x ( x + 10 ) - 2x ( 8 ) + [tex]\frac{2x(x)}{2}[/tex] + [tex]\frac{2x(x+2)}{2}[/tex]

A(x) = 4x² + x² + x² + 40x - 16x + 2x

A(x) = 6x² + 26x

Answer:

B) 12

Step-by-step explanation:

Given:

ΔABC ~ ΔDEC

AB ~ DE

AC ~ DC

BC ~ EC

We will just use ratios and substitute DE as x:

[tex]\frac{AB}{AC} =\frac{DE}{DC} \\\\\frac{16}{20} =\frac{x}{15} \\\\20x=240\\\\x=\frac{240}{20} \\\\x=12[/tex]

DE = 12

The measure of the side DE of the triangle DEC will be 12. Then the correct option is B.

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees. If two triangles are similar, then the ratio of the corresponding sides will remain constant.

The triangles ABC and DEC are similar triangles. Then the ratio of the corresponding sides will be the same.

DE/AB = CD/AC

From the diagram, AB = 16, AC = 20, and CD = 15. Then the measure of the side DE will be given as,

DE/16 = 15/20

DE/16 = 0.75

DE = 16 x 0.75

DE = 12

The measure of the side DE of the triangle DEC will be 12. Then the correct option is B.

Answer:

ratio of all flowers in the vase to daisies,= 11:8

ratio of roses to daisies= 3:8

Step-by-step explanation:

the total number of flowers in the vase is 11

but there are 3 roses,

therefore the number of daisies is 11-3 which is 8

the infor on the rations can be directly derived from this figures.

Step-by-step explanation:

Intersecting lines make equal opposite angles

2x + y = 50 - y

     2x = 50 - 2y

       x = 25 - y

A straight line represents 180°

4x + 6y + 2x + y + 2x + 3y = 180

                            8x + 10y = 180

                  8(25 - y) + 10y = 180

                  200 - 8y + 10y = 180

                                     2y = -20

                                       y = -10

       x = 25 - (-10)

       x = 35

Answer:

1) [tex]v=4.5[/tex]

2)[tex]c=6.3[/tex]

3)[tex]g=0.4[/tex]

4)[tex]a=17.4[/tex]

For those who have images blocked:

1) v = 4.5

2) c = 6.3

3) g = 0.4

4) a = 17.4

(a) mtan refers to the slope of the tangent line. Given f(x) = 9 + 7x ², compute the difference quotient:

[tex]\dfrac{f(x+h)-f(x)}h = \dfrac{(9+7(x+h)^2)-(9+7x^2)}h = \dfrac{(9+7x^2+14xh+7h^2)-9-7x^2}h = \dfrac{14xh+7h^2}h[/tex]

Then as h approaches 0 - bearing in mind that we're specifically considering h near 0, and not h = 0 - we can eliminate the factor of h in the numerator and denominator, so that

[tex]m_{\rm tan} = \displaystyle \lim_{h\to0}\frac{f(x+h)-f(x)}h = \lim_{h\to0}\frac{14xh+7h^2}h = \lim_{h\to0}(14x+7h) = 14x[/tex]

and so the slope of the line at P (0, 9), for which we take x = 0, is 0.

(b) The equation of the tangent line is then y = 9.

Step-by-step explanation:

Using the combination formula, it is found that there is a 0.2448 = 24.48% probability that the six claims selected will include one workers compensation claim, two homeowners claims and three auto claims.

Combination formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by:

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The desired outcomes are:

Thus:

[tex]D = C_{2,1}C_{4,2}C_{7,3} = \frac{2!}{1!1!} \times \frac{4!}{2!2!} \times \frac{7!}{4!3!} = 420[/tex]

For the total outcomes, six claims from a set of 13, thus:

[tex]T = C_{13,6} = \frac{13!}{6!7!} = 1716[/tex]

The probability is:

[tex]p = \frac{D}{T} = \frac{420}{1716} = 0.2448[/tex]

0.2448 = 24.48% probability that the six claims selected will include one workers compensation claim, two homeowners claims and three auto claims.
