Suppose a spider moves along the edge of a circular web at a distance of 3cm from the center.

1 answer:

7 0

When we say southwest, we refer to the direction of the spider by which it is directly 45° downward in Quadrant III. In other words, it is 225° from the positive x-axis. The values are obtained by multiplying the given radius by the sine and cosine of the angle.
x-coordinate = (3 cm)(cosine 225°) = -2.12 cm
y-coordinate = (3 cm)(sine 225°) = -2.12 cm
Therefore, the coordinate of the spider is,
(-2.12, -2.12)

Solve the equation by using the Square Root Property.<br><br><br><br> 16x2 + 16x + 4 = 81

Maslowich

Answer:

$x = \dfrac{7}{4}, x = \dfrac{-11}{4}$

Step-by-step explanation:

We are given the following equation in the question:

$16x^2 + 16x + 4 = 81$

We have to find the solution of the equation using square root property.

We can solve the equation as:

$16x^2 + 16x + 4 = 81\\(4x)^2 + 2(4x)(2) + (2)^2 = 81\\\text{Identity: }(a+b)^2 = a^2 + b^2 + 2ab\\\Rightarrow (4x+2)^2 = 81\\ \Rightarrow (4x+2) = \sqrt{81}\\ \Rightarrow (4x+2) = \pm 9\\ \Rightarrow (4x+2) = 9, (4x+2) = -9\\\Rightarrow 4x = 7, 4x = -11\\\Rightarrow x = \dfrac{7}{4}, x = \dfrac{-11}{4}$

is the required solution of the equation.

Answer:

Step-by-step explanation:

Because it says that Alex wants to spend exactly $30 so you want to have 30 as the total ( = 30 )

and it says 18 plus, you only add 18 one time ( 18 + )

and then it says 0.12 per mile, so you need to do something times 0.12 + 18 and get exactly 30. so you do ( 0.12x ) in this case we're not solving it we're just doing the equation so it's just 0.12x instead of a specific number

Put it all together and you get 18 + 0.12x = 30

Hope this helps dude
