Kipish [7]3 years ago

Answer:

x = -0.441 and x = -2.359

Step-by-step explanation:

The given equation is :

2(5x+7)^2-13=33

Adding 13 to both sides of the equation.

2(5x+7)^2-13+13=33+13\\\\2(5x+7)^2=46\\\\(5x+7)^2=23

So,

5x+7=\sqrt{23}\\\\5x+7=\pm4.795\\\\5x=4.795-7, 5x=-4.795-7\\\\5x=-2.205, 5x = -11.795\\\\x=-0.441, x=-2.359

So, the solution of the given equation is x = -0.441 and x = -2.359.

Determine whether the vectors u and v are parallel, orthogonal, or neither.
Komok [63]
<span>The dot product here is 10(9) + 6(5)=120
so the vectors are not orthogonal 
</span><span>u.v = |u| x |v| cos (theta) ; theta is the angle between them 

we know from above that u.v = 120 

|u| = sqrt[10^2+6^2]=11.66
|v| = sqrt[9^2+5^2]=10.29

so we know: 

theta =cos^-1 120/(11.66x10.29)
so theta = 25 degrees</span><span>

The final product of the given expression is 36 41/29

<h3>Given the expression below;</h3>

(3 2/3 * 3 3/2) * (4 2/3)

Expand using the distributive property to have;

(3 2/3 * 4 2/3) * (3 3/2 * 4 2/3)

Simplify the parenthesis to have;

(11/3 * 14/3) * (9/2 * 14/3)

154/9 * 126/6

36 41/29
