Answer:

p, because Triangle ABC is similar to triangle EDC

Step-by-step explanation:

<h3>Given</h3>

The triangles have a common vertex C
m∠ABC = 70°
m∠BAC = p
m∠CDE = 70°
m∠CED = ?

<h3>Solution</h3>

As C is common vertex, the angles BCA and DCE are vertical angles and therefore have same measure

<u>Sum of angles of ABCΔ:</u>

70° + p + ∠C = 180°

<u>Sum of angles of ΔEDC:</u>

70° + ∠CED + ∠C = 180°

<u>Comparing the sums above we get:</u>

∠CED = p

<u>Correct option is the last one:</u>

p, because Triangle ABC is similar to triangle EDC

Write a definite integral that represents the area of the region. (Do not evaluate the integral.) y1 = x2 + 2x + 3 y2 = 2x + 12F

Svet_ta [14]

Answer:

$A = \int\limits^3__-3}{9}-{x^{2}} \, dx = 36$

Step-by-step explanation:

The equations are:

$y = x^{2} + 2x + 3$

$y = 2x + 12$

The two graphs intersect when:

$x^{2} + 2x + 3 = 2x + 12$

$x^{2} = 0$

$x_{1} = 3\\x_{2} = -3$

To find the area under the curve for the first equation:

$A_{1} = \int\limits^3__-3}{x^{2} + 2x + 3} \, dx$

To find the area under the curve for the second equation:

$A_{2} = \int\limits^3__-3}{2x + 12} \, dx$

To find the total area:

$A = A_{2} -A_{1} = \int\limits^3__-3}{2x + 12} \, dx -\int\limits^3__-3}{x^{2} + 2x + 3} \, dx$

Simplifying the equation:

$A = \int\limits^3__-3}{2x + 12}-({x^{2} + 2x + 3}) \, dx = \int\limits^3__-3}{9}-{x^{2}} \, dx$

Note: The reason the area is equal to the area two minus area one is that the line, area 2, is above the region of interest (see image).

Larry paid $4.16 for 4 tomatoes. At this same rate, how much would 7 tomatoes cost?

Anna71 [15]

The question is asking us to find how much seven tomatoes would cost. Well, to get our answer, we must first find the cost of one tomato. We are given the information that paying $4.16 for 4 tomatoes. All we have to do now is divide 4.16 by 4, to get the price of one tomato. This gives us $1.04. Now, just multiply 1.04 by 7 to get 7.28. Therefore, the price of seven tomatoes is C. $7.28. Hope this helped and have a phenomenal day!
