X^8 = ()^2

x^8 = (x^4)^2

x^8 = x^8

inside the parethesis is x^4

[Find all the missing side and angles of this triangle]

nydimaria [60]

Step-by-step explanation:

We have AB = 7, Angle ABC = 70°

and Angle ACB = 90°.

Angle BAC = 180° - 70° - 90° = 20°

(Sum of angles in a triangle = 180°)

Using Trignometry,

AC = 7sin70° = 6.58.

BC = 7cos70° = 2.39.

A triangular flag has an area of 493 square meters and a height of 17 meters. What is the length of the base

ahrayia [7]

Answer:

$\frac{984}{17}$ or around 57.88

Step-by-step explanation:

We can find the base length by using the formula for the area of a triangle.

$A=\frac{bh}{2}$

Plug in the values that we know, the area and the height, and solve for $b$ .

$493=\frac{17b}{2}$

$984=17b$

$b=\frac{984}{17}So the base is [tex]\frac{984}{17}$ or about 57.88 if you round to the nearest hundredth.

Recall that a reinforcement beam will extend from one strut to the other when the two struts are 2 feet apart. Algebraically det

Karo-lina-s [1.5K]

Answer:

Here is the full question:

Another plan to secure the roller coaster involves placing two concrete struts on either side of the center of the leg of the roller coaster to add reinforcement against southerly winds in the region. Again, using the center of the half-circle as the origin, the struts are modeled by the equations and . A vertical reinforcement beam will extend from one strut to the other when the two cables are 2 feet apart.

Graph the two struts on the model of the roller coaster. Take a screenshot of your graph and paste the image below, or sketch a graph by hand.

Recall that a reinforcement beam will extend from one strut to the other when the two struts are 2 feet apart.

(a) Algebraically determine the x -value of where the beam should be placed.

(b) Explain where to place the beam

Step-by-step explanation:

Find attached the graphing calculator.

(a) The x-value where the beam should be placed is x = -4

(b) The beam should be placed directly above 4 feet from the center.
