Answer:

x= -7

Step-by-step explanation:

We need to solve the following root equation:

\sqrt[3]{x-1} + 2 = 0

1. First, we need to add minus two to both sides of the equation:

\sqrt[3]{x-1}= -2

2. Elevate each side of the equation to the power of 3:

x-1= -8

3. Solve for 'x':

x= -8 + 1

x= -7

Therefore, the result is:

x= -7✔️

Suppose a projectile is fired from a cannon with velocity v0 and angle of elevation θ. The horizontal distance Rθ it travels (in
jolli1 [7]

Answer:

0.25 rad to the nearest hundredth radian

Step-by-step explanation:

Here is the complete question

Suppose a projectile is fired from a cannon with velocity vo and angle of elevation (theta). The horizontal distance R(θ) it travels (in feet) is given by the following.  

R(θ) = v₀²sin2θ/32

If vo=80ft/s what angel (theta) (in radians) should be used to hit a target on the ground 95 feet in front of the cannon?

Do not round any intermediate computations, and round your answer(s) to the nearest hundredth of a radian.

(θ)= ?rad

Solution

R(θ) = v₀²sin2θ/32

If v₀ = 80 ft/s and R(θ) = 95 ft

θ = [sin⁻¹(32R(θ)/v₀²)]/2

= [sin⁻¹(32 × 95/80²)]/2

=  [sin⁻¹(3040/6400)]/2

=  [sin⁻¹(0.475)]/2

= 28.36°/2

= 14.18°

Converting 14.18° to radians, we have 14.18° × π/180° = 0.2475 rad

= 0.25 rad to the nearest hundredth radian

The probability of event A occurring is 50%, and the probability of event B occurring is 25%. Events A and B are nonsimultaneous
Misha Larkins [42]

Answer:

The probability of event A occurs but event B does not occur = P(A)* Probability of event B does not occur = 0.375

Step-by-step explanation:

The probability of event A occurring = 50% = 0.5

The probability of event B occurring = 25%  = 0.25

Events A and B are non simultaneous events.

The probability of event B does not occur = 1 - P(B)

= 1- 0.25

= 0.75

So the probability of event A occurs but event B does not occur = P(A)* Probability of event B does not occur

= 0.5*0.75

= 0.375

Thank you.

4 + 6x + 5 = 7x Could someone help me? Thanks :) And could you also show how u did it
matrenka [14]

Answer:

x=9

Step-by-step explanation:

combine like terms

4+6x+5=7x

4+5=9

9+6x=7x

to get 6x with 7x subtract 6x from both sides as its positive

6x-6x=0

7x-6x=x

9=x

x=9
