Surface area = 2(ab+bc+ac)
a=5.2 ft,  b=2.4 ft, c=3.5ft

Surface area = 2(5.2 * 2.4 + 2.4 * 3.5 + 3.5 * 5.2) =
                         2(12.48 + 8.4 + 18.2) = 
                         2 * 39.08 =
                         78.16 ≈ 78.2 ft²   ← <span>to the nearest tenth</span>

Si la amplitud del complemento de un ángulo agudo es mayor, menor o igual que la del suplemento de un ángulo agudo. ¿podes respo
Harrizon [31]

Answer:

Dados dos ángulos vecinos, ambos son complementarios si la suma de sus medidas es igual a 90° y suplementarios si esa suma de medidas es igual a 180°. Puesto que uno de los ángulos es el ángulo agudo mencionado en el enunciado, es decir, un ángulo cuya medida es mayor que 0° y menor que 90°. Entonces, el ángulo complementario debe ser inevitablemente menor que el ángulo suplementario.

Step-by-step explanation:

HELP ME I DON'T UNDERSTAND IT :(
a_sh-v [17]

Answer:

D

Step-by-step explanation:

A is (-8,8) so you would divide each 8 by 4 because 8 divided by 1/4 so you will have (-2,2)

B is (-8,4) so divide the by 1/4 which would be (-2,1)

C is (4,-4) so divide that and and you get (1,-1)

What type of conic section is represented by the parametric equations below? X=3cos(t)-1 y=3sin(t)+4
Andrei [34K]

Answer:

Circle

Step-by-step explanation:

Examples of conic sections are the circle, the ellipse, the parabola and the hyperbola. Parametric equations are used to express the x and y variables in terms of a less complicated manner using a third variable (t or θ).

The parametric equation for a circle with an equation (x-h)^2+(y-k)^2=r^2 is given by:

x=rcos(t)+h, y=rsin(t)+k

where r is the radius of the circle and (h, k) is the center of the circle.

A conic section with a parametric equations X=3cos(t)-1, y=3sin(t)+4 is a circle with center at (-1, 4) and radius of 3. The equation of the circle is:

(x + 1)² + (y - 4)² = 3²

Pls help due ASAP <br> Show workings
ElenaW [278]

Answer:

YW = 6

Step-by-step explanation:

a^2 + b^2 = c^2

x^2 + 8^2 = 10^2

x^2 + 64 = 100

x^2 + 64 - 64 = 100 - 64

x^2 = 36

√x^2 = √36

x = 6
