Step-by-step explanation:
I think iv seen this question somewhere so did u forget to put 22?
Here is the explaination if u did...
5T -22 = 83
revenue minus expense = profit

3-2(k-2)-7(2k-3)
Answer:
- 16k + 28
Step-by-step explanation:
3 - 2(k - 2) - 7(2k - 3) ← distribute parenthesis
= 3 - 2k + 4 - 14k + 21 ← collect like terms
= - 16k + 28
Answer:28−16k
Step-by-step explanation:
3−2(k−2)−7(2k−3)
Use the distributive property to multiply −2 by k−2.
3−2k+4−7(2k−3)
Add 3 and 4 to get 7.
7−2k−7(2k−3)
Use the distributive property to multiply −7 by 2k−3.
7−2k−14k+21
Combine −2k and −14k to get −16k.
7−16k+21
Add 7 and 21 to get 28.
28−16k

d/d{cosec^-1(1+x²/2x)} is equal to
Step-by-step explanation:
[tex]\large\underline{\sf{Solution-}}[/tex]
[tex]\rm :\longmapsto\:\dfrac{d}{dx} {cosec}^{ - 1} \bigg( \dfrac{1 + {x}^{2} }{2x} \bigg)[/tex]
Let assume that
[tex]\rm :\longmapsto\:y = {cosec}^{ - 1} \bigg( \dfrac{1 + {x}^{2} }{2x} \bigg)[/tex]
We know,
[tex]\boxed{\tt{ {cosec}^{ - 1}x = {sin}^{ - 1}\bigg( \dfrac{1}{x} \bigg)}}[/tex]
So, using this, we get
[tex]\rm :\longmapsto\:y = sin^{ - 1} \bigg( \dfrac{2x}{1 + {x}^{2} } \bigg)[/tex]
Now, we use Method of Substitution, So we substitute
[tex] \red{\rm :\longmapsto\:x = tanz \: \rm\implies \:z = {tan}^{ - 1}x}[/tex]
So, above expression can be rewritten as
[tex]\rm :\longmapsto\:y = sin^{ - 1} \bigg( \dfrac{2tanz}{1 + {tan}^{2} z} \bigg)[/tex]
[tex]\rm :\longmapsto\:y = sin^{ - 1} \bigg( sin2z \bigg)[/tex]
[tex]\rm\implies \:y = 2z[/tex]
[tex]\bf\implies \:y = 2 {tan}^{ - 1}x[/tex]
So,
[tex]\bf\implies \: {cosec}^{ - 1}\bigg( \dfrac{1 + {x}^{2} }{2x} \bigg) = 2 {tan}^{ - 1}x[/tex]
Thus,
[tex]\rm :\longmapsto\:\dfrac{d}{dx} {cosec}^{ - 1} \bigg( \dfrac{1 + {x}^{2} }{2x} \bigg)[/tex]
[tex]\rm \: = \: \dfrac{d}{dx}(2 {tan}^{ - 1}x)[/tex]
[tex]\rm \: = \: 2 \: \dfrac{d}{dx}( {tan}^{ - 1}x)[/tex]
[tex]\rm \: = \: 2 \times \dfrac{1}{1 + {x}^{2} } [/tex]
[tex]\rm \: = \: \dfrac{2}{1 + {x}^{2} } [/tex]
Hence,
[tex] \purple{\rm :\longmapsto\:\boxed{\tt{ \dfrac{d}{dx} {cosec}^{ - 1} \bigg( \dfrac{1 + {x}^{2} }{2x} \bigg) = \frac{2}{1 + {x}^{2} }}}}[/tex]
Hence, Option (d) is correct.
Taylor states that 2,800,000 in scientific notation is 2.8 x 10 -6 because the number has six places to the right of the 2. Is Taylor's reasoning correct?
Scientific Notation is the way of writing a number or expressing them in a shorter or more compact way.
No, Taylor's resoning is incorrect because 2,800,000 = [tex]2.8 * 10^{6}[/tex]
From the question, we are given:
2,800,000 .
2,800,000 in scientific notation is [tex]2.8 * 10^{6}[/tex].
The reason the power is not to the negative 6 is that we are moving from the right-hand side to the left-hand side 6 times.
Therefore, Taylor's reasoning is incorrect.

Solve the equation: 3/8g + 2 = 5
Answer:
3/8g + 2 = 5
Subtract the number 2 from both sides of the equation.
3/8g = 3
Now divide 3/8 from both sides of the equation.
3/8 divided by 3/8 equals 0. 3 divided by 3/8 equals 8.
The final answer is:
g = 8
------------------------------------------------------------------------------------------
Check your answer:
3/8g + 2 = 5
Substitute 8 into the spot where the variable g was.
3/8 X 8 + 2 = 5
So our answer x = 8 is true.

5. Gardener Gary planted 21 rows of tomatoes
and squash. He planted twice as many rows of
tomatoes as rows of squash. How many tomato
plants were planted if there are 12 plants per
row?
Answer:
168
Step-by-step explanation:
first find out how many rows of squash there are
21 = x + 2x
21 = 3x
7 = x
then find out how many rows of tomatoes there are
7 × 2 = 14
if there are 12 plants per row, we can multiply
14 × 12 = 168
Gardener Gary planted 168 tomato plants
How to determine the number of yellow leaves?Let the rows of tomato be x and the rows of squash be y.
So, we have:
x + y = 21
The statement twice as many rows of tomatoes as rows of squash means that:
x = 2y
Substitute x = 2y in x + y = 21
2y + y = 21
This gives
3y = 21
Divide by 3
y = 7
Substitute y = 7 in x = 2y
x = 2 * 7
x = 14
This means that Gary planted 14 rows of tomato.
The number of tomato plants is then calculated using
Tomato plants= 14 * plants per row
This gives
Tomato plants = 14 * 12
Evaluate the product
Tomato plants = 168
Hence, Gardener Gary planted 168 tomato plants
