5 feet 11 inches plus 3 feet 5 inches equals 8 feet 16 inches, but there is 12 inches in a foot, and 16 inches - 12 = 4 inches, add the one foot you took away to 8. The answer is 9 feet 4 inches.

2 = f/8 Solve the equation.

MaRussiya [10]

Answer:

f = 16

Step-by-step explanation:

Isolate the variable, f. Note the equal sign, what you do to one side, you do to the other. Multiply 8 to both sides of the equations:

2 = (f/8)

2(8) = (f/8)(8)

f = 2 * 8 = 16

f = 16 is your answer.

Find equation of set of points pieces that its distance from the point 3, 4, -5 and -2, 1, 4 are equal.

Gnesinka [82]

Answer:

Step-by-step explanation:

Suppose we a point $P(x,y,z)$ such that its distance from either the point $A(3,4,-5)$ or $B(-2,1,4)$ is the same.

Using this information we can formula:

distance AP = distance BP

first, let's find the distance from AP, using the distance formula.

$r = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2 + (z_1 - z_2)^2}$

$AP = \sqrt{(3 - x_2)^2 + (4 - y_2)^2 + (-5 - z_2)^2}$

similarly, we can find the distance BP

$BP = \sqrt{(-2 - x_2)^2 + (1 - y_2)^2 + (4 - z_2)^2}$

since both distances are exactly the same we can equate them

$AP = BP$

$\sqrt{(3 - x_2)^2 + (4 - y_2)^2 + (-5 - z_2)^2} = \sqrt{(-2 - x_2)^2 + (1 - y_2)^2 + (4 - z_2)^2}$

we can simplify it a bit squaring both sides, and getting rid of the subscripts.

$(3 - x)^2 + (4 - y)^2 + (-5 - z)^2 = (-2 - x)^2 + (1 - y)^2 + (4 - z)^2$

what we have done here is formulated an equation which consists of any point P that will have the same distance from (3,4,-5) and (-2,1,4).

To put it more concretely,

This is the equation of the the plane from that consists of all points (P) from which the distance from both (3,4,-5) and (-2,1,4) are equal.

Help me find x please

Sedaia [141]

Answer:

$\displaystyle 13 = x$

Step-by-step explanation:

All three angles in an equilateral triangle are equivalent, and they sum up to 180°, so each angle measures 60°:

60° = [8x - 44]°

+ 44° + 44°

____________

$\displaystyle \frac{104°}{8} = \frac{[8x]°}{8} \\ \\ 13° = x$

I am joyous to assist you anytime.

Given that sin? x + cos2x = 1

Pachacha [2.7K]

Answer:

the answer is

$\frac{ \sqrt{23} }{5}$

cause sin²x= 2/25

so cos²x would be 1-2/25= 23/25

then cos x is what I wrote as the answer
