1.uhhh I don't wanna explain all of it but basically a straight line is 180 degrees and the parallel lines are important because they are the reason that 5 and 1 are equal, etc.

2. Again, parallel lines play a big role. If it helps, 3 5 and 4 are all equal angles because of the parallel lines

How can a mixed number be written as a sum?
k0ka [10]
First, write the mixed number as a sum of a whole number and a proper fraction. Then write the two parts with common denominator , and add. Once you're used to this, you can use a shortcut method: 1) Multiply the whole part by the denominator of the fractional part, and add the numerator of the fractional part.

The instantaneous rate of change of the function f(x) = −4x² − 3x + 1 at the point x = -3 is 21.

<h3>What is the instantaneous rate of change of the function at the given point?</h3>

The instantaneous rate of change is simply the change in the derivative value at a specific point.

Given the data in the question;

  • f(x) = −4x² − 3x + 1
  • Point x = -3

To determine the instantaneous rate of change of the function, first find the derivative of the function.

f(x) = −4x² − 3x + 1

Applying sum rule, with respect to x

d/dx[ -4x² ] + d/dx[ -3x ] + d/dx[ 1 ]

[ 2 × -4x¹ ] + [ 1 × -3x⁰ ] + d/dx[ 1 ]

[ -8x ] + [ -3 ] + d/dx[ 1 ]

-8x - 3 + d/dx[ 1 ]

Differentiate using constant rule

-8x - 3 + [ 0 ]

-8x - 3

f'(x) = -8x - 3

Next, plug x = -3 into the derivative and simplify.

f'(x) = -8x - 3

f'(-3) = -8(-3) - 3

f'(-3) = 24 - 3

f'(-3) = 21

Therefore, the instantaneous rate of change of the function f(x) = −4x² − 3x + 1 at the point x = -3 is 21.

Jack and Jim went biking. Jack biked for 5 1/3 hours with average speed 12 1/2 miles per hour. Jim traveled exactly 1 1/5 as far
ahrayia [7]
Given that Jack biked for 5 \frac{1}{3} hours with an average speed of  12 \frac{1}{2} miles per hour.

The distance travelled by Jack is given by

d=speed\times time \\  \\ =12 \frac{1}{2}\times5 \frac{1}{3}= \frac{25}{2} \times \frac{16}{3}  \\  \\ = \frac{200}{3} =66 \frac{2}{3} \ miles

Given that Jim travelled exactly 1 \frac{1}{5} as far as Jack did, then the distance Jim travelled is given by

d=1 \frac{1}{5} \times66 \frac{2}{3}  \\  \\ = \frac{6}{5} \times \frac{200}{3} =80

Therefore, the length of Jim's journey is 80 miles.
