find the equation of the line tangent to the graph of f at (1,4), where f is given by f(x)=2x^3-3x^2+5

Answer:

The side lengths are 84, 63 and 28

Step-by-step explanation:

The shortest side of a triangle is 13 cm.

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.

Answer:

3 : 4

Step-by-step explanation:

Given:

ratio of people who voted to total number of registered voters:

To find the approx ratio, round both numbers to the nearest hundred:

Therefore, 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

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

Answer:

Solution:

Here,the denominators are 3 and 8

We 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.

Step-2: Compare both the fractions.

Since 16/24 is greater than 12/24, 2/3 is greater than 4/8.

Answer:

If it INCREASES then it is going closer towards zero since it is negative. So subtract 8 from (-7) and you get -15

Step-by-step explanation:

it asks how many the shelf can hold which would mean you should divide :

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.
