Answer:
[tex]y = 4[/tex]
Step-by-step explanation:
First, find the derivative of f:
[tex]\displaystyle \begin{aligned} f'(x) & = \frac{d}{dx}\left[ 2x^3 - 3x^2 + 5\right] \\ \\ & = 6x^2 - 6x \\ \\ & = 6x(x-1)\end{aligned}[/tex]
Find the instantaneous slope at x = 1:
[tex]\displaystyle \begin{aligned} f'(1) & = 6(1)((1)-1) \\ \\ &= 0 \end{aligned}[/tex]
From the point-slope form, find the equation of the line:
[tex]\displaystyle \begin{aligned}y - y_1 & = m(x-x_1) \\ \\ y - (4) & =(0)(x-(1)) \\ \\ y & = 4 \end{aligned}[/tex]
In conclusion, the equation of the tangent line is y = 4.

Answer:
The mode if 5, because 5 occurs 8 times, which is more than any other numbers occurring more than once. The median is 6, and this is because when you line up the numbers in order and cross them off to find the middle number, it is 6. I rounded to the mean to about 6.4. I got this by adding all of the numbers up, or by doing 12 + 40 +18 +7, etc, and got the total of 165. Because there is a total of 26 data points, I divided those numbers and got 6.3461, which ends up rounding to 6.4.

Solve for x.
−7x−15<6
Answer:
x > -22/7
Step-by-step explanation:
Given inequality:
- 7x - 15 < 6
adding 15 to both sides:
==> -7x - 15 + 15 < 6 + 16
==> -7x < 22
dividing both sides by 7:
==> -x < 22/ 7
multiplying both sides by -1
(anytime you multiply the inequality by -1 you must flip the inequality sign– replace the "<" with ">")
==> x > -22/7
Which is greater 2/3 or 4/8?
Answer:
Solution:
Here,the denominators are 3 and 8
Multiples of 3=3,6,9,12,15,18,21,24.....Multiples of 8=8,16,24,32,40......Same smallest number=24We have,3×8=24 and 8×3=24.
Now,
[tex] \displaystyle{ \frac{2}{3} = \frac{2 \times 8}{3 \times 8} = \frac{16}{24} }[/tex]
[tex] \displaystyle \frac{4}{8} = \frac{4 \times 3}{8 \times 3} = \frac{12}{24} [/tex]
Since,16>12,
So,
[tex] \displaystyle \: \frac{16}{24} > \frac{12}{24} [/tex]
i.e.
[tex] \displaystyle \frac{2}{3} > \frac{4}{8} [/tex]
Method of cross product:
[tex] \displaystyle \: \frac{2}{3} \: or \: \frac{4}{8} [/tex]
[tex] \displaystyle2 \times 8 = 16 \: \: \: \: \: > \: \: \: \: \: 3 \times 4 = 12[/tex]
[tex]16 > 12[/tex]
[tex] \displaystyle \therefore \: \frac{2}{3} > \frac{4}{8} [/tex]
[tex] \displaystyle{Thus,the \: fraction \: \frac{2}{3} \: is \: greater \: than \: the \: fraction \: \frac{4}{8} . }[/tex]
Step-by-step explanation:
[tex] \frak \green{BrainlyFairy}[/tex]
Solution:
Step-1: Make the denominators of both fractions the same.
2/3 and 4/8=> 2 x 8/3 x 8 and 4 x 3/8 x 3=> 16/24 and 12/24Step-2: Compare both the fractions.
16/24 and 12/24 = 2/3 and 4/8=> 16/24 > 12/24Since 16/24 is greater than 12/24, 2/3 is greater than 4/8.

Solve. The perimeter of a triangle is 50 centimeters. Find the lengths of its sides, if the longest side is 8 centimeters longer than the shortest side, and the remaining side is 3 centimeters longer than the shortest side.
Answer:
The side lengths are 84, 63 and 28
Step-by-step explanation:
The shortest side of a triangle is 13 cm.
How to estimate the shortest side of a triangle?Let x be the longest side
y be the shortest side
z be the other side
x + y + z = 50 ...........(1)
x = y + 8 ...........(2)
z = y + 3 ............(3)
Replace x with y+8 in equation 1
Replace z with y + 3 in equation 1
To estimate the value for y,
(y+8) + y + (y+3) = 50
Simplifying the above equation, we get
3y + 11 = 50
3y = 50-11
3y = 39
y = 39/3
y = 13 cm
Therefore, the shortest side of a triangle is 13 cm.

There are 1213 registered voters in Paul's village. During the last election 887 people actually voted. Which of the following is approximately the ratio of the number of the people who voted to the total number of registered voters in the village?
Answer:
3 : 4
Step-by-step explanation:
Given:
1213 = total number of registered voters887 = people who votedratio of people who voted to total number of registered voters:
To find the approx ratio, round both numbers to the nearest hundred:
887 ≈ 9001213 ≈ 1200Therefore, 887 : 1213 ≈ 900 : 1200
The greatest common factor of 900 and 1200 is 300,
so we can reduce the ratio further by dividing both sides by 300:
⇒ 900 : 1200 = 3 : 4
