Solve for x. Round your answer to the nearest tenth (0.1)

Marizza181 [45]

Answer:

$x\approx 7.0$

Step-by-step explanation:

Since we are given a right triangle, we can use right trigonometric ratios.

x is the opposite side to our angle. 10 is the adjacent side to it. Thus, we can use the tangent ratio:

$\displaystyle \tan(\theta^\circ)=\frac{\text{opposite}}{\text{adjacent}}$

Substitute:

$\displaystyle \tan(35^\circ)=\frac{x}{10}$

Solve for x:

$x=10\tan(35^\circ)$

Use a calculator:

$x=7.0020...\approx 7.0$

A baseball is hit with a bat and, as a result, its direction is completely reversed and its speed is doubled. If the actual cont

alexandr402 [8]

Answer:

6.7 /s.

Step-by-step explanation:

Initial velocity = u m/s

From the question, final velocity, v = - 2u m/s

Note - (the minus sign indicates that the direction was reversed and doubled)

t = 0.45

From equation of motion,

v = u + at

Acceleration, a = (v - u)/t

= (-2u - u)/0.45

= - 3u/0.45

Acceleration, a/Original speed, u = 3/0.45

= 6.7 /s

Please help me with my math I’m so bad at this

mojhsa [17]

Answer:

Step-by-step explanation:

(-9)^1/3 * (-81)^1/3

We can rewrite -81 as 9 * -9

So it can be rewritten as:

(-9)^1/3 * (9*-9)^1/3

Since they are all raised to the 1/3, we can combine the bases:

(-9*9*-9)^1/3 =

(9*9*9)^1/3, because the two negatives turn into a positive:

So this is basically:

(9^3)^1/3 = 9^1 = 9

Marianna [84]

Answer:

The location of the point is between Quadrant II and Quadrant III

Step-by-step explanation:

we know that

The abscissa refers to the x-axis and ordinate refers to the y-axis

in this problem we have

the coordinates of the point are $(-x,0)$

see the attached figure to better understand the problem

The location of the point is between Quadrant II and Quadrant III
