Answer:
y=3x−4
Step-by-step explanation:
find the tangent line to f(x)=x2−3x+5 at x=3
First, find the value of the function at the given point: y0=f(3)=5
Second, find the slope of the tangent line, which is the derivative of the function, evaluated at the point: m=f′(3)
Find the derivative: f′(x)=2x−3
Next, we evaluate the derivative at the given point to find the slope.
m=f′(3)=3
Finally, the equation of the tangent line is y−y0=m(x−x0)
Plug the values that we found, we get that y−(5)=3(x−(3))
So basically: y=3x−4

-20 ≥ z - 13
z=?
Answer:
The final answer is:
[tex]-7 \geq z[/tex]
Step-by-step explanation:
Solve the inequality:
[tex]-20 \geq z - 13[/tex]
-Add 13 both sides of the equation:
[tex]-20 +13 \geq z - 13 +13[/tex]
[tex]-7 \geq z[/tex]
So, the answer is [tex]-7 \geq z[/tex] .

So ya see, it really does peak at the given times.
The point (-3,2) lies on a circle whose equation is (x + 3)^2 + (y + 1 )^2 =r^2. Which of the following must be the radius of the circle?
Answer:
1. 3
2. A
Step-by-step explanation:
1. (-3+3)^2 + (2 + 1)^2 - r^2 = 0
0 + 9 - r^2 = 0
r^2 = 9
r = 3
2. 2x^2 + 4x + 2y^2 + 12y = - 6
Divide by 2.
(x^2 + 2x) + (y + 6y) = -3
Remember how to complete the square..
(b/2)^2
So...
(2/2) ^ 2 = 1
(6/2) ^ 2 = 9
(x^2 + 2x + 1) + (y^2 + 6y + 9) = -3 + 1 + 9 <--- You must remember to add whatever you add on the left to the right!
Now.. rewrite in standard form..
(x+1)^2 + (y+3)^2 = 7
Careful!! the circle equation is written as
(x - h)^2 + (y - h)^2 = r^2
Meaning that the radius is square root of 7. At center (-1, -3)

Answer:
It will take 7 hours for car B to catch up to Car A.
Step-by-step explanation:
So if you write the the two equations out:
[tex]Car A=70x\\Car B= 90x-140[/tex]
You'll want to assume that x is how many hours and y is how many km.
The reason car B has, -140, is because car A is in front of it by two hours and in those two hours it reached 140km. Meaning that Car B is starting at 140 km behind Car A.
If you graph these two equations out you'll realize that they intersect at the point (7, 490). Meaning that Car B caught up with Car A after 7 hours and both cars had traveled 490km.

A recipe for cookies calls for 1 cup of butter,
twice as much sugar as butter, and three times
as much flour as sugar. How many cups of
flour will you need if you halve the recipe?
(Hint: Halving an amount is the same as
dividing the amount by 2)
cups of flour
Answer:
3 cups
Step-by-step explanation:
the original recipe calls for 6 cups of flour (3 times as much as sugar. sugar is 2 cups, times 3 is 6)
half it: 6/2 = 3
Answer:
3 cups of flour.
Step-by-step explanation:
If sugar is twice as much as butter, we need 2 cups of sugar.
If flour is 3 times as much as sugar, we'll need 6 cups.
Half of 6 is 3.

(a) n is an integer.
−2 < n ≤ 3
List the possible values of n.
Then solve;
Solve 3y − 4 > 17
The possible integer values of n are:
-1, 0, 1 , 2 , and 3.
-1 to 3 are all greater than -2.
3 is the maximum since 3 is the greatest number where n is equal to it or lesser than it.
Solving the inequality: 3y - 4 > 17
3y - 4 > 17
Add 4 to both sides to move it.
3y > 17 + 4
3y > 21
Divide both sides by 3 to get the value of y.
3y/3 > 21
y > 7
The sign does not change since we did not divide or multiply by a negative.
Therefore, y is greater than 7.

3 1/2 - 4 2/5
how do i do this?
Answer:
Ok so first you would have to turn them into improper fractions which is
3 [tex]\frac{1}{2\\}[/tex] = [tex]\frac{7}{2}[/tex] and 4 [tex]\frac{2}{5}[/tex] = [tex]\frac{22}{5}[/tex]
So now that you have made them both improper fractions you have to find common denominators.
To find common denominators you must multiply both the numerator and the denominator by the same thing. Since your oposing fraction has a denominator of 5 you can know that a even number wont go in an odd number so take [tex]\frac{22}{5}[/tex] and mutiply both numbers by 2 and get [tex]\frac{44}{10}[/tex]. Then mutiply both numbers in [tex]\frac{7}{2}[/tex] by 5 to get a common denominator.
[tex]\frac{35}{10}[/tex]
[tex]\frac{35}{10} -[/tex] [tex]\frac{44}{10}[/tex] =35 - 44 = -9 so your answer is [tex]-\frac{9}{10}[/tex]
Step-by-step explanation:
A tree was 63 inches tall. Several years later it was 107 inches tall.
What was the percent increase, to the nearest hundredth, of the height of the tree? Enter the answer in the box.
percent
Answer:
69.84%
Step-by-step explanation:
percentage increase
[tex]\frac{107-63}{63} \times 100\\=\frac{44}{63} \times 100\\=\frac{4400}{63} \\=69.84/%[/tex]
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Required percentage value = a
total value = b
Percentage = a/b x 100
The percentage increase in the height of the tree is 69.84%.
What is a percentage?
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Height of the tree = 63 inches.
Height after several years = 107 inches.
Now,
The percentage increase in the height of the tree.
= (107 - 63)/63 x 100
= 44/63 x 100
= 69.84%
Thus,
The percentage increase in the height of the tree is 69.84%.
