Answer:

La longitud de los lados congruentes =

B = 8.5cm

C = 8.5 cm

Step-by-step explanation:

El perímetro del triángulo isósceles mide 24 cm.

El lado no congruente mide 7 cm de largo.

Lados congruentes significa lados que son iguales o iguales entre sí.

El perímetro de un triángulo es =

Lado A + Lado B + Lado C

Por lo tanto,

24 = 7 cm + B + C

24 - 7 = B + C

17 cm = B + C

Los dos lados son congruentes,

B = C

Por lo tanto, 17 cm / 2

= 8.5 cm

La longitud de los lados congruentes =

B = 8.5 cm

C = 8.5 cm

Answer:

A

Step-by-step explanation:

In standard form, an ellipse's major axis is indicated by the a^{2}, b^{2} terms like this:

\frac{{(y-k)}^{2}}{a^{2}}+\frac{(x-h)^{2}}{b^{2}}, a>b

\frac{{(x-h)}^{2}}{a^{2}}+\frac{(y-k)^{2}}{b^{2}}, a>b

In the top equation, the vertical axis is primary and in the second the horizontal axis is primary. That's a bit more info than the question asked, but I thought it may be helpful to understand the answer.

Now, a co-vertex is the intersection point between an ellipse and its minor axis. On the graph of the ellipse, the b is the distance from the center to where the ellipse intersects its minor axis, so our answer is A.

If a graphical representation would be helpful, I would take a look at the Math Warehouse article on the Equation of an Ellipse in Standard Form.

Arrange the graphs in descending order (from highest to lowest) based on the values of their correlation coefficients.
Scrat [10]
Basically, the closer they fit to the imaginary line of best fit, the higher they are

the closer the dots are to the imaginary line, te higher the number

D looks the closest together so that is first
A is a little farther apart
C is farther
B is farthers
