bearhunter [10]

4/4 is bigger than 7/8 because if u divide 4/4 it equals to 1 and 7/8 is 0.875 so which is bigget 4/4 or 7/8 4/4 i hope this helps have a nice day =)

How to solve these two problems ？

puteri [66]

8) $\theta$ is -0.896 radians

9) length of arc is 41.91 cm

Solution:

Given that,

$tan\ \theta = \frac{-5}{4}$

$\theta$ is in quadrant 4

To find: $\theta$

From given,

$tan\ \theta = \frac{-5}{4}\\\\\theta = tan^{-1} \frac{-5}{4}\\\\\theta = tan^{-1} (-1.25)\\\\\theta = -51.34$

Thus value of $\theta$ is -51.34 degrees

Convert degrees to radians

$-51.34\ degree = -51.34 \times \frac{ \pi }{180}\ radian\\\\-51.34\ degree = -0.896\ radian$

Thus $\theta$ is -0.896 radians

From given,

radius = 15.4 cm

$\theta = \frac{13 \pi }{15}$

The length of arc when angle in radians is:

$arc\ length = r \times \theta\\\\arc\ length = 15.4 \times \frac{ 13 \pi }{15}\\\\arc\ length = 15.4 \times 2.721\\\\arc\ length = 41.91$

Thus length of arc is 41.91 cm

Which expression is equivalent to -

dedylja [7]

$x^\frac{4}{3} x^ \frac{2}{3}$ Lets get started :)

Referring to the picture I have uploaded might help you
We have the same base, which in this case is x.

When multiplication occurs in the same base, we add the powers
$x^\frac{4}{3} x^ \frac{2}{3}$
↓ (I am going to perform the problem separately and then give the final answer as the power to x)
$\frac{4}{3} + \frac{2}{3}$ = $\frac{6}{3} = 2$
↓
x²

$(x^2)^ \frac{1}{3}$

The power of a power should be performed by multiplying the powers together.
2 x $\frac{1}{3}$ = $\frac{2}{3}$

$x^\frac{2}{3}$

Your final answer will be the second option

lesya [120]

Answer:

Step-by-step explanation:

8x+5=29, x=3

subtract 5 on each side

8x=24

then divide by 8 on both sides to isolate x

x=3

Question 10 of 10

Alika [10]

Answer:

D. y = -1/3x

Step-by-step explanation:

The line through the origin means the equation will be a proportion of the form y = kx. (You can also see this by looking at the answer choices.) The value of k is ...

k = y/x . . . . . divide the above equation by x

For the given point (x, y) = (-3, 1), the value of k can be seen to be ...

k = 1/-3 = -1/3

Then the equation for the line is ...

y = -1/3x . . . . matches D
