Answer:
For f(x) to be differentiable at 2, k = 5.
Step-by-step explanation:
For f(x) to be differentiable at x = 2, f(x) has to be continuous at 2.
For f(x) to be continuous at 2, the limit of f(2 – h) = f(2) = f(2 + h) as h tends to 0.
Now,
f(2 – h) = 2(2 – h) + 1 = 4 – 2h + 1 = 5 – 2h.
As h tends to 0, lim (5 – 2h) = 5
Also
f(2 + h) = 3(2 + h) – 1 = 6 + 3h – 1 = 5 + 3h
As h tends to 0, lim (5 + 3h) = 5.
So, for f(2) to be continuous k = 5

HURRY PLEASE On a coordinate plane, point A is 2 units to the left and 5 units up. Point B is 5 units to the right and 5 units up. What is the distance between the points? Point A is located at the point . Point B is located at the point . The distance between the points is units.
Answer:
point A is located at (-2,5) and point B is located at point (5,5), the distance between the points is 7 units. hope this helps!
The distance between the points will be 7 units. Point A is located at the point (-2, 5). Point B is located at the point (5, 5).
What is distance between points?The formula of distance between two points is A(x₁, y₁) and B(x₂, y₂) is given by: [tex](A,B) = \sqrt{( x_{2} - x_{1} )^2 + ( y_{2} - y_{1})^2}[/tex]
We have,
Point A (-2, 5) and Point B (5, 5).
i.e.
x₁ = -2, x₂ = 5 and
y₁ = 5, y₂ = 5
Now,
Using the above mentioned formula of distance,
i.e.
Distance [tex](A,B) = \sqrt{( x_{2} - x_{1} )^2 + ( y_{2} - y_{1})^2}[/tex]
So,
Substituting values,
Distance [tex](A,B) = \sqrt{(5-(-2) )^2 + ( 5-5)^2}[/tex]
Now, simplify,
Distance [tex](A,B) = \sqrt{(7)^2 + 0}[/tex]
We get,
Distance [tex](A,B) = 7[/tex]
So, the distance between AB is 7 units.
Hence, we can say that the distance between the points will be 7 units. Point A is located at the point (-2, 5). Point B is located at the point (5, 5).

the ratio of strawberries to grapes in the fruit salad is 3:9. the ratios of strawberries to honey dew is 6:14. if there 36 grapes. how many strawberries?
Answer:
12 strawberries
Step-by-step explanation:
Represent strawberry with S, grape with G and honeydew with H
Given
[tex]S : G = 3 : 9[/tex]
S : H = 6 : 14
Required
Solve for S when G = 36
To do this, we make use of the first ratio
[tex]S : G = 3 : 9[/tex]
Substitute 36 for G
[tex]S : 36 = 3 : 9[/tex]
Convert to fractions
[tex]\frac{S}{36} = \frac{3}{9}[/tex]
[tex]\frac{S}{36} = \frac{1}{3}[/tex]
Multiply both sides by 36
[tex]36 * \frac{S}{36} = \frac{1}{3} * 36[/tex]
[tex]S = \frac{1}{3} * 36[/tex]
[tex]S = \frac{36}{3}[/tex]
[tex]S = 12[/tex]
Hence, there are 12 strawberries

Louis and Ricardo took a timed a reading test, and the results below show the number of words each student can read per minute which student reads at a faster rate ?
Answer:
Louis reads faster
Step-by-step explanation:
See attachment for complete question.
The table represents Louis data while the graph represents Ricardo's data.
To solve this question, we simply calculate the slope of the table/graph,
The slope (m) is calculated by:
[tex]m=\frac{y_2 - y_1}{x_2 - x_1}[/tex]
For Louis:
From the table, we pick any corresponding x and y values
[tex](x_1,y_1) = (2,436)[/tex]
[tex](x_2,y_2) = (6,1308)[/tex]
[tex]m_1 = \frac{1308 - 436}{6-2}[/tex]
[tex]m_1 = \frac{872}{4}[/tex]
[tex]m_1 = 218[/tex]
For Ricardo:
From the graph, we pick any corresponding x and y values
[tex](x_1,y_1) = (2,300)[/tex]
[tex](x_2,y_2) = (6,900)[/tex]
[tex]m_2 = \frac{900- 300}{6-2}[/tex]
[tex]m_2 = \frac{600}{4}[/tex]
[tex]m_2 = 150[/tex]
So, we have:
Louis: [tex]m_1 = 218[/tex]
Which means 218 words per minutes
Ricardo: [tex]m_2 = 150[/tex]
Which means 150 words per minutes

What is 75% of 800?
A; 9 3/8
B; 10.66
Answer:
it's 600
Step-by-step explanation:
that's not an option there but...
10% of 800 is 80
5% of 800 is 40
80 × 7 = 560
560 + 40 = 600
Which is the correct answer?
(Note): (if you give me a silly or absurd answer I will report you)
Step-by-step explanation:
Since N ≡ 0 (mod 2) and N ≡ 0 (mod 3),
N ≡ 0 (mod (2*3)) ≡ 0 (mod 6).
Hence when N is divided by 6,
the remainder is 0. (A)

Shiloh needs to randomly select one of the six days between Sunday and Friday. Which simulation tools could she use in this situation?
((( MULTIPLE ANSWERS))
A-a spinner divided evenly into 12 sections, with each section a different color
B-two coins
C-a six-sided number cube
D-a bag containing 12 chips in two different colors, with six of each color
E-two full suits from a standard deck of cards
Answer:
The correct answer is C. She could use a six-sided number cube.
Step-by-step explanation:
Since Shiloh has 6 options from which to choose a unique alternative, it can be stated that her eligibility ratio is 1/6. Thus, since the dice has 6 numbers and only 1 will come up face up, the option of the dice is the most appropriate to make her decision.
On the other hand, the other options do not contemplate 6 possibilities but 12, 2, 12 and 13 possibilities respectively, with different possible alternatives, which does not give an equitable distribution of possibilities between each option.
