Step-by-step explanation:
2y^4 x 5y^3 = 10y^7
3gh^2 x 4g^3h^3 = 12g^4h^5
Answer:
1) 10y^7
2)12g^4h^5
Step-by-step explanation:
First just multiply numbers the rule is to add the exponents and if it doesn't show an exponent it should be 1 as an exponent so 2x5 is 10 and 4+3 is 7 so 10y^7 you do the same for the other one

Answer: 16 + 55 = 71cm^2
Step-by-step explanation:
You want to divide this figure into 2 rectangles. There are two ways to do this, but either one will give you the same answer.
First One:
It has the dimensions of 5 and 11. 5 x 11 = 55cm^2
Second One:
This one wont be straightforward like the first one. You need to find these sides manually.
7 + x = 11
x = 4
Then,
9 - x = 5
x = 4
4 x 4 = 16cm^2

If f(x) is a linear function and given f(3)=−3 and f(8)=1, determine the linear function. a.) What is the slope? (Be sure to leave your answer in reduced fraction form.) b.) What is the y-intercept? (Be sure to leave your answer in reduced fraction form.) c.) What is f(x)? f(x)=
Answer:
slope is 4/5
y intercept is -27/5
f(x) = 4/5x -27/5
Step-by-step explanation:
The slope is
f(8) - f(3)
----------------
8-3
1 - -3
------------
8-3
1+3
------------
5
4/5
We can use the slope intercept form to find the y intercept
y = mx+b where m is the slope and b is the y intercept
y = 4/5x +b
Using the point (8,1)
1 = 4/5(8)+b
1 = 32/5 +b
Subtract 32/5 from each side
5/5-32/5 = b
-27/5 = b
y = 4/5x -27/5
f(x) = 4/5x -27/5
*I WILL MARK YOU BRAINLIEST!!!!!*
Answer:
C
Step-by-step explanation:
you were told to draw a graph
f(x) or y is 4 when x less than or equal to 3. so you must draw straight horizontal line at y = 4 start from x = 3 to the left
(fx) or y is 2 when x bigger than 3. so, 3 is not included. so you must draw straight horizontal line at y = 2 start from x = 3 to the right with empty circle first (it means 3 not included)

David worked 7 1/3 hours today and planted 11 trees. It takes him about the same amount of time to plant each tree. How long did it take him to plant each tree?
Answer:
2/3 hours or 40 mins.
Step-by-step explanation:
No. of trees planted by David = 11
No. of hours worked by David to plant 11 trees = 7 1/3 hours = (7*3 + 1) /3 = 22/3
It takes him about the same amount of time to plant each tree
let time taken to plan 1 tree be x
then time taken to plan 1*11 tree = 11*x
But, given that total time taken is 22/3 hours
thus,
11x = 22/3 hours
x = 22/(3 *11) = 2/3
Thus, it took 2/3 hours to plant each tree.
As 1 hour has 60 minutes
Time taken in minutes to plant 1 tree = 2/3 *60 mins = 40 mins
It takes David 2/3 hours to plant each tree.
Since it takes David 7 1/3 hours today to plant 11 trees.
Therefore time taken to plant 11 trees = 7 1/3 hours = 22/3 hours
The time taken to plant each tree = 22/3 hours ÷ 11 trees = 2/3 hours per tree
Therefore it takes David 2/3 hours to plant each tree.

What is the product? One-eighth times three-elevenths 3 over 88 1 over 22 4 over 19 35 over 88
Answer:
[tex]\frac{3}{88}[/tex]
Step-by-step explanation:
Given
One-eighth times three-elevenths
Required
Solve
One-eighth means 1/8
Three-elevenths means 3/11
So, mathematically; the above expression is represented as thus:
[tex]\frac{1}{8} * \frac{3}{11}[/tex]
To solve this, we simply multiply the numerator and the denominator together.
After multiplying these together, the next is to check if the resulting can be simplified
If yes,we simplify it and if otherwise, we live it like that.
So,
[tex]\frac{1}{8} * \frac{3}{11}[/tex]
[tex]=\frac{1 * 3}{8 * 11}[/tex]
[tex]= \frac{3}{88}[/tex]
At this point, the fraction can't be simplified any further.
Hence,
[tex]\frac{1}{8} * \frac{3}{11} = \frac{3}{88}[/tex]

Tenga en cuenta que i = √(-1), i es el representante de un número complejo.
x = -1.129i, -0.241i, 0.241i or 1.129i.
Note that i = √(-1), i is the representative of a complex number.
Step-by-step explanation:
Pregunta correcta
¿Me pueden ayudar en esta ecuación biquadratica, por favor: 9x⁴ = —12x² - 6/9
Solución
9x⁴ = —12x² - 6/9
9x⁴ + 12x² + 6/9 = 0
multiplicar por 9
81x⁴ + 108x² + 6 = 0
Deje x² = y, entonces x⁴ = y²
81y² + 108y + 6 = 0
Resolviendo esta ecuación cuadrática
y = -0.0581 o y = -1.275
Recordemos, x² = y
x = ±√y
Si y = -0.0581
x = ± √(-0.0581) = ± 0.241i = 0.241i o -0.241i
Si y = -1.275
x = ± √(-1.275) = ± 1.129i = 1.129i o -1.129i
x = -1.129i, -0.241i, 0.241i o 1.129i.
Tenga en cuenta que i = √(-1), i es el representante de un número complejo.

Correct Question
Can you help me in this biquadratic equation, please: 9x⁴ = —12x² — 6/9
Solution
9x⁴ = —12x² — 6/9
9x⁴ + 12x² + 6/9 = 0
multiply through by 9
81x⁴ + 108x² + 6 = 0
Let x² = y, then x⁴ = y²
81y² + 108y + 6 = 0
Solving this quadratic equation
y = -0.0581 or y = -1.275
Recall, x² = y
x = ±√y
If y = 0.0581
x = ±√(-0.0581) = ±0.241
If y = -1.275
x = ± √(-1.275) = ± 1.129i = 1.129i or -1.129i
Hence x = -1.129i, -0.241i, 0.241i or 1.129i.
Note that i = √(-1), i is the representative of a complex number.

Which answer choice shows the correct calculation by using the Pythagorean Theorem for the distance of
between Elibri's apartment and Elibri's school, namely HE?
Answer:
|AC| = 4.47 units (question attached as image)
Step-by-step explanation:
The question lacks sufficient details. We wil however consider a similar example (image attached) to understand how to solve questions using Pythagoras theorem.
We will calculate for |AC| using Pythagoras theorem, we have:
|AC|² = |AB|² + |BC|²
|AC| = ?, |AB| = 4 units, |BC| = 2 units
|AC|² = 4² + 2² = 16 + 4
|AC|² = 20 ⇒ |AC| = [tex]\sqrt{20}[/tex]
|AC| = 4.472135955 ≈ 4.47
|AC| = 4.47 units
The average reading score on a certain test is given by y=0.150x +255.34 where x is the number of years past 1970 . In what year would the average reading score be 259.24 if this model was accurate
Answer:
The average was 259.24 in 1996.
Step-by-step explanation:
In order to find the year that the average, "y", is 259.24 we need to apply this value on the given expression, as done below:
[tex]259.24 = 0.15*x + 255.34\\0.15*x = 259.24 - 255.34\\0.15*x =3.9\\x = \frac{3.9}{0.15}\\x = 26[/tex]
The average was 259.24 after 26 years, therefore it was in 1996.

Answer:
68°
Step-by-step explanation:
a triangle hold 180° so 180-43=137 and G and H are almost the same value where G is 69° and H is 68°
Step-by-step explanation:
x°+43°+(x-1)°=180°(sum of all the interior angle of triangle is 180°
2x°+42°=180°
2x°=180°-42°
2x°=138°
x=138°/2°
:. x=69°
Now,
angle H= (x-1)°=69°-1°=68°
:. angle H= 68°

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar. What is the output of the function f(x) = x + 21 if the input is 4? When the input is 4, the output of f(x) = x + 21 is .
Answer:
When the input is 4, the output of f(x) = x + 21 is 25.
Step-by-step explanation:
The given function is
[tex]f(x)=x+21[/tex]
Here, x is input and f(x) is output.
We need to find the output of the given function f(x) if the input is 4.
Substitute x=4 in the given function.
[tex]f(4)=4+21[/tex]
[tex]f(4)=25[/tex]
So, the output value is 25.
When the input is 4, the output of f(x) = x + 21 is 25.

Answer:
The x-intercepts are (-2, 0) and (4, 0). I know this because it's written in intercept notation. To find the y-intercept we'll expand.
-(x + 2)(x - 4) = -x² + 2x + 8 so the y-int. is (0, 8). To find the rest we'll complete the square.
-x² + 2x + 8 = -(x² - 2x) + 8 = -(x -1)² + 1 + 8 = -(x - 1)² + 9 so the vertex is (1, 9) and the axis of symmetry is x = 1. This means that the domain is all real numbers and the range is y ≤ 9.
