I need the slope of this graph
shtirl [24]

Answer:

3/2

Step-by-step explanation:

Pick two points on the graph

(-1,2) and (3,8)

We can use the slope formula

m= ( y2-y1)/(x2-x1)

   = ( 8-2)/(3 - -1)

   = (8-2)/(3+1)

   = 6/4

  = 3/2

Two sides of an acute triangle measure 5 inches and 8 inches. The length of the longest side is unknown.
nordsb [41]

The greatest whole possible whole number length of the unknown side is 9 inches

<em><u>Solution:</u></em>

Two sides of an acute triangle measure 5 inches and 8 inches

The length of the longest side is unknown

We have to find the length of unknown side

The longest side of any triangle is a hypotenuse

<em><u>For a acute triangle we know:</u></em>

If c is the longest side of a acute triangle, a and b are other two sides of a acute triangle then the condition that relates these three sides are given as:

c^2

Here in this sum,

a = 5 inches

b = 8 inches

c = ?

Substituting we get,

c^2< 5^2+8^2\\\\c^2 < 25 + 64\\\\c^2 < 89\\\\c < 9.4

On rounding to nearest whole number,

c < 9

Hence, to the greatest whole possible whole number length of the unknown side is 9 inches

If f(1) = 13 and f '(x) ≥ 3 for 1 ≤ x ≤ 3, how small can f(3) possibly be?
tangare [24]

Answer:

The answer to this question is 19.

Step-by-step explanation:

Given that :

f(x)=13.

f'(x)=3.   1 ≤ x ≤ 3.

Integrate

∫f'(x) dx=∫3 dx

f(x)=3x+c        1 ≤ x ≤ 3.

f(1)= 3+c  

c=13-3 =10.

f(x)=3x+10  1 ≤ x ≤ 3.

now ,

f(3)=3(3)+10=19.

So f(3) is at least 19.

Answer:

m (slope) = 37

Step-by-step explanation:

use the slope-line formula, y2 - y1/x2 - x1

put in coordinates (5, 20) for x1 and y1

put in coordinates (4, -17) for x2 and y2

simplify
