(X^2-1)(x^2-49)
So for the first one take
X^2=1
X=1
The second
X^2=49
X=7
X=7,1

$(x^2-49)(x^2-1) = (x-7)(x+7)(x-1)(x+1) = 0, so x = 7, x = -7, x = 1, x = -1.$

For the given central angle, determine the distance traveled along the unit circle from the point (1,0). 57

aliina [53]

Answer: (a)- $0.99\ \text{units}$

Step-by-step explanation:

Given

Central angle is $57^{\circ}$

The radius of the unit circle is $1\ \text{unit}$

Arc length is given by

$\Rightarrow l=\dfrac{\theta}{360^{\circ}}\times 2\pi r$

Put the values

$\Rightarrow l=\dfrac{57}{360}\times 2\pi \cdot1\\\\\Rightarrow l=0.99\ \text{units}$

If you look at a state map with a representative fraction scale of 1:500,000; the straight-line distance between two cities is e

Leya [2.2K]

Answer:

Step-by-step explanation:

The scale factor is given as 1:500,000

i.e. original 500,000 is represented as 1 inch in the map

Hence if 12.7 inches on the map, this is a question of direct variation

So actual distance = 12.7(500000) = 6350000

SOLVE FOR X. pls i need help

Lyrx [107]

X=8
Set up proportions would give you: 10/3x+1 = 22/7x-1
With that in mind, cross multiply, which would give you: 10(7x-1) = 22(3x+1).
Turns into: 70x -10 = 66x+22. Then just solve for x
