Answer:
[tex]\frac{8}{\left(-x+2\right)^2}[/tex] & [tex]x = 1, x = 3[/tex]
Step-by-step explanation:
I'm sure you are familiar with the product rule,
If y = u*v => dy/dx = u * dv/dx + v * dy/dx <----- product rule
In this case:
[tex]u=3x+2,\:v=\left(2-x\right)^{-1},\\=>\frac{d}{dx}\left(3x+2\right)\left(2-x\right)^{-1}+\frac{d}{dx}\left(\left(2-x\right)^{-1}\right)\left(3x+2\right)[/tex]
Now remember the sum rule:
[tex]\frac{d}{dx}\left(3x+2\right) = \frac{d}{dx}\left(3x\right)+\frac{d}{dx}\left(2\right),\\\frac{d}{dx}\left(3x\right) = 3,\\\frac{d}{dx}\left(2\right) = 0\\\frac{d}{dx}\left(3x+2\right) = 3[/tex]
For this second bit we apply the chain rule:
[tex]\frac{d}{dx}\left(\left(2-x\right)^{-1}\right) = -\frac{1}{\left(2-x\right)^2}\frac{d}{dx}\left(2-x\right),\\\frac{d}{dx}\left(2-x\right) = -1,\\\\=> -\frac{1}{\left(2-x\right)^2}\left(-1\right)\\=> \frac{1}{\left(2-x\right)^2}[/tex]
If we substitute these values back into the expression...[tex]\frac{d}{dx}\left(3x+2\right)\left(2-x\right)^{-1}+\frac{d}{dx}\left(\left(2-x\right)^{-1}\right)\left(3x+2\right)[/tex]
...we get the following:
[tex]3\left(2-x\right)^{-1}+\frac{1}{\left(2-x\right)^2}\left(3x+2\right)[/tex]
The rest is just pure simplification:
[tex]3\left(2-x\right)^{-1}+\frac{1}{\left(2-x\right)^2}\left(3x+2\right)\\= \frac{3}{-x+2}+\frac{3x+2}{\left(-x+2\right)^2}\\= \frac{3\left(-x+2\right)}{\left(-x+2\right)^2}+\frac{3x+2}{\left(-x+2\right)^2}\\\\= \frac{3\left(-x+2\right)+3x+2}{\left(-x+2\right)^2}\\\\= \frac{8}{\left(-x+2\right)^2}[/tex]
Now let's equate this to equal 8 for the second bit and solve for x:
[tex]\frac{8}{\left(-x+2\right)^2}=8,\\\frac{8}{\left(-x+2\right)^2}\left(-x+2\right)^2=8\left(-x+2\right)^2,\\8=8\left(-x+2\right)^2,\\\left(-x+2\right)^2=1,\\x = 1, x = 3[/tex]

Find the measure of the following angles.
Answers
Answer:
[tex] m\angle A = 79\degree[/tex]
[tex] m\angle B = 112\degree[/tex]
Step-by-step explanation:
ABCD is a cyclic Quadrilateral.
Opposite angles of a cyclic quadrilateral are supplementary.
Therefore,
[tex] m\angle A + m\angle C = 180\degree[/tex]
[tex] m\angle A + 101\degree = 180\degree[/tex]
[tex] m\angle A = 180\degree-101\degree[/tex]
[tex] \red{\bold {m\angle A = 79\degree}} [/tex]
[tex] m\angle B + m\angle D = 180\degree[/tex]

mary says that the expression a/2 has no terms because there are no plus or minus signs explain whether her reasoning is correct
Answers
Answer:
No, her reasoning is wrong
Step-by-step explanation:
Her reasoning is not correct because for one the expression clearly has a term. a/2 is a term on its own. So she concluding that a/2 isn't a term is quite wrong. Again, her basis for conclusion being that there exists no addition or subtraction signs makes the equation not being a term wrong, as well. Even though there isn't and subtraction nor addition sign, it does not stop it from being any less of a term

Step-by-step explanation:
3.12 * 10^8
=========
2.6 * 10^5
Start by doing 3.12 / 1.6 = 1.2 and that is the correct number of sig digs.
Now get the power on the 10. When dividing, the powers subtract.
10^(8 - 5)
10^ 3

The computation of the number of second would be
In the case when the ball would hit the ground, the ball height would be zero
So the following equation would be

Answers
Answer:
A and D and E
Step-by-step explanation:
Substitute the variable(in this case) t for 3, then use the order of operations to simplify(PEMDAS), which will give you 33 for both expressions. To see if two expressions are equivalent, you need to substitute the variable for an odd number AND an even number, so next, substitute the variable t for the number 6, which will give you 51 for both expressions. That means the expressions are equivalent

5 cm
12 cm
Answers
9514 1404 393
Answer:
A) (3 cm x 4 cm ÷ 2) x 3 cm
Step-by-step explanation:
The volume is the product of the area of the triangular bases and the distance between them.
Each right triangular base has a width of 3 cm and a height of 4 cm. Its area will be given by ...
A = (1/2)bh
A = (1/2)(3 cm)(4 cm) = (3 cm × 4 cm) ÷ 2
__
The distance between the triangular bases is marked at the left side of the diagram as 3 cm. So, the volume is ...
V = Bh
V = (3 cm × 4 cm ÷ 2) × 3 cm . . . . . matches choice A
There aren't any more steps. The answer starts by saying how the volume is computed. Then it shows how to find the numbers that go into that computation. Finally, it puts all that together in the form that is required to match an answer choice.
It might also be useful for you to draw the net to scale on a piece of paper, cut it out, and fold it along the lines to actually make a triangular prism. A little hands-on is always helpful in math. It only takes 5 or 10 minutes and can give you great insight into both prisms and nets.

3&4. using the diagrams, is there enough information given to prove that the triangles are congruent? if so, state the theorem you would use
5&6. name the third congruence statement that is needed to prove that ABC is congruent to XYZ using the given theorem
Answers
Answer:
3. There is enough information to prove that ΔABC and ΔDEF are congruent using the Angle-Side-Angle (ASA) congruency theorem
4. More information is required to prove that ΔGFH and ΔJKL are congruent
5. ∠B ≅ ∠Y
6. ∠A ≅ ∠X
Step-by-step explanation:
3. In triangle ΔABC, and triangle ΔDEF, we have;
Corresponding angles ∠A and ∠D are congruent
Corresponding angles ∠C and ∠F are congruent
Corresponding side in between the given angles [tex]\overline{AC}[/tex] and [tex]\overline{DF}[/tex] are congruent
Therefore ΔABC is congruent to ΔDEF by the Angle-Side-Angle (ASA) rule of congruency
4. The corresponding angles ∠F and ∠J in triangle ΔGFH and triangle ΔJKL are congruent as well as the corresponding adjacent sides to the given angles and the corresponding opposite sides to the given angles are congruent, however, there is not enough information to prove that the two triangles are congruent
The included angles, ∠H and ∠L between the sides congruent corresponding sides should be congruent or the other adjacent sides [tex]\overline{FG}[/tex] and [tex]\overline{JK}[/tex] to the congruent angles ∠F and ∠J should be congruent for the triangles ΔGFH and ΔJKL to be congruent
5. Given [tex]\overline{AC}[/tex] ≅ [tex]\overline{XZ}[/tex], ∠C ≅ ∠Z, using the Angle-Angle-Side, AAS, rule of congruency, we have;
The angles adjacent to ∠C and ∠Z, and opposite to [tex]\overline{AC}[/tex] and [tex]\overline{XZ}[/tex], which are B and ∠Y are congruent
Therefore, we have;
∠B ≅ ∠Y using AAS rule of congruency
6. Using Angle-Side-Angle, ASA, rule, given;
[tex]\overline{AC}[/tex] ≅ [tex]\overline{XZ}[/tex], ∠C ≅ ∠Z, then the angles on the other side of [tex]\overline{AC}[/tex] and [tex]\overline{XZ}[/tex] which are ∠A and ∠X should be congruent, we have;
∠A ≅ ∠X
Keith mowed his aunt's yard 12 times. Each time, he mowed for 1.75 hours and he earned $8.40 per hour. How much money, to the nearest cent, did Keith earn mowing his aunt's yard?
Answers
Answer: $176.40
Step-by-step explanation:
Keith mowed the yard 12 times.
Each time he mowed took 1.75 hours.
The number of hours he took in total is therefore:
= 12 * 1.75 hours
= 21 hours
He gets paid $8.40 for every hour he works. For the 21 hours therefore, he would earn:
= 8.40 * 21 hours
= $176.40
write an equation of the form y equals MX for the line shown below if appropriate use the decimals for the slope 2.5 0.0
Answers
Answer:
y = 2.5x
Step-by-step explanation:
The equation of line WX is y = −2x − 5. Write an equation of a line perpendicular to line WX in slope-intercept form that contains point (−1, 1).
y = 1 over 2 x − 3 over 2
y = − 1 over 2 x − 3 over 2
y = 1 over 2 x + 3 over 2
y = negative 1 over 2 x + 3 over 2
Answers
Answer:
third option
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 2x - 5 ← is in slope- intercept form
with slope m = - 2
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-2}[/tex] = [tex]\frac{1}{2}[/tex] , then
y = [tex]\frac{1}{2}[/tex] x + c ← is the partial equation
To find c substitute (- 1, 1) into the partial equation
1 = - [tex]\frac{1}{2}[/tex] + c ⇒ c = 1 + [tex]\frac{1}{2}[/tex] = [tex]\frac{3}{2}[/tex]
y = [tex]\frac{1}{2}[/tex] x + [tex]\frac{3}{2}[/tex] ← equation of perpendicular line
