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.

Answer: the person above me is wrong, the answers are 8:11 and 8:3

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:

(2, 2)

Step-by-step explanation:

Moving right and left is the x-axis. Moving up and down is the y-axis. Moving right would be positive and moving left would be negative. Moving down would be negative and moving up is positive. In general, look at or visualize a coordinate plane.

Answer:

196 / 10

Step-by-step explanation:

Not sure but hope it helps

To find the x-intercept, you need to see where the line intersects the x-axis, the horizontal line with numbers on it. The line intersects the x-axis at (2, 0). Therefore, the x-intercept is (2, 0).

To find the y-intercept, you need to see where the line intersects the y-axis, the vertical line with numbers on it. The line intersects the y-axis at (1, 0). Therefore, the y-intercept is (1, 0).

There are two ways to find the slope. The easiest one in my opinion is rise over run, but you can also use an equation too. I am going to be showing you the rise/run method, but you can also ask if you want the equation method as well. First of all, the line goes to the left, not the right, so we know that the slope is going to be negative. The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x). All you need to do is calculate the difference between the two points in the vertical direction (rise) and then divide it by the difference in the horizontal direction (run). I am going to choose point (1, 0) if I go up by 2 and over by 4, I'll get to the point (-4, 3) that also lands on the line. 2/4 is 1/2. Therefore, the slope is -1/2.

I hope this helps! Let me know if I got something wrong.

Answer:

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

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.

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.

(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.
