Answer:
cuberoot(a) - 1/tenthroot(a)
Step-by-step explanation:
The applicable rule of exponents seems to be ...
(a^b)^c = a^(bc)
a^-b = 1/a^b
__
Expressing all radicals using rational exponents, we want to simplify ...
[tex]a^{\frac{1}{3}}-(a^{\frac{2}{5}})(a^{-\frac{1}{2}})\\\\=a^{\frac{1}{3}}-a^{\frac{4-5}{10}}\\\\=a^{\frac{1}{3}}-a^{-\frac{1}{10}}=\boxed{\sqrt[3]{a}-\dfrac{1}{\sqrt[10]{a}}}\\\\=\boxed{\sqrt[3]{a}-\dfrac{\sqrt[10]{a^9}}{a}}[/tex]
__
We have shown two simplified expressions. You can choose the one that matches your requirements. Sometimes we don't want any radicals in the denominator.

The side of a square was reduced by 3 in and the other side was enlarged by 5 in. The area of a new rectangle is 9 square inches. Find the side of a square
Answer:
4
Step-by-step explanation:
Give the other guy a 5 star my dude lol
The square has a property of having all the sides equal. The rectangle on the other hand has its opposite sides equal. The larger side of the rectangle is called length and the smaller side is called breadth. The area of rectangle is the product of length and breadth i.e.
[tex]\rm Area\:of\:rectangle = Length\: \times Breadth[/tex]
The side of square for the given question is [tex]4\rm \: inches[/tex].
Calculation:Let the side of square be [tex]\rm x[/tex]
Given:
Area of rectangle is 9 square inches.
Side of square is reduced by 3 and other side is enlarged by 5. Therefore, dimensions of the rectangle will be:
[tex]\rm Breadth = x - 3\\\\Length = x + 5[/tex]
[tex]\rm Area\:of\:rectangle = Length\: \times Breadth\\\\9 = (x + 5)(x -3)\\\\9 = x^2 + 5x -3x -15 \\\\9 = x^2 +2x - 15 \\\\0 = x^2 +2x-15-9\\\\0 = x^2+2x-24\\\\[/tex]
On factoring the equation:
[tex]\begin{aligned} \rm x^2 + 2x -24 &= 0\\\\x^2 + 6x - 4x - 24 &= 0\\\\x(x+6)-4(x+6) &= 0\\\\(x+6)(x-4)&=0\end[/tex]
On equating [tex]\rm (x +6)[/tex] and [tex](x-4)[/tex] with 0 we get:
[tex]x = -6\\\\x=4[/tex]
Since side of square cannot be negative, [tex]x = 4[/tex] is the only correct value.
Therefore the side of square is [tex]4 \:\rm inches[/tex].

Math help!
Answer:
14.42cm and 59 degrees
Step-by-step explanation:
Use the pythagorean theorem to find the length of AB
24^2 + AB^2 = 28^2 ---> 14.42
Do arcsin(24/28) to get 59 degrees since 24 is the opposite and 28 is the hypotenuse.

Domain or range and function or not
Answer:
This is a function.
domain = [1, 6]
range = [1, 4]
Step-by-step explanation:
A relation that maps elements from one set (domain) into another set (input) is called a function only if each element of the domain is mapped into only one element in the range.
For a function y = f(x) the domain is the set of the possible x-values, and the range is the set of the possible y-values.
In this case we can see that the possible values of x is the interval [1, 6]
Where we have a closed interval because we have black dots, meaning that these values are included in the sets.
We also can see that the range is the interval [1, 4]
And we also can see that all the x-values are mapped into only one y-value, then this is a function.

Answer:
530.66 square cm
Step-by-step explanation:
A=pi*r^2
A=pi*13^2
A=530.66
Answer:
A = 530.91 [tex]cm^2[/tex]
Step-by-step explanation:
The formula to find the area of a circle is ([tex]A = (pi)r^2[/tex]), where ([tex]A[/tex]) represents the area of the circle, ([tex]pi[/tex]) represents the value ([tex]3.1415...[/tex]), and ([tex]r[/tex]) represents the radius of the circle. Use this knowledge, and substitute in the given information, to solve for the area of the circle.
[tex]A = (pi)r^2\\\\A = (3.1415)(13)^2\\\\A = (3.1415)169\\\\A = 530.91[/tex]
The drawing shows a heart-shaped figure. The heart is composed of a square and two semicircles. The semicircles have the center in the middle of two of the sides.
a) Set up a formula to calculate the area of the heart.
Answer:
Area = πx² + x² or x²(π + 1)
Step-by-step explanation:
The area of the heart = area of a circle + area of the square
Note:
1. The 2 semicircles makes 1 full circle
2. The diameter of the circle = the side length of the square
Thus:
Area of the heart = πr² + s²
Where,
r = x
s = x
Formula for area of the heart = π(x²) + x² = πx² + x²
Area = x²(π + 1)

A tank was filled with 225L 156 ml of water
on the first day and 106 L 215ml of water on
the second day. 38 L 162ml of water used by
the family members. Find out how much
water is still left in the tank?
Answer:
There are 293 liters and 209 milliliters of water left in the tank.
Step-by-step explanation:
Since a tank was filled with 225L 156 ml of water on the first day and 106 L 215ml of water on the second day, and that 38 L 162ml of water were used by the family members, to find out how much
water is still left in the tank, the following calculation must be performed:
(225,156 + 106,215) - 38,162 = X
331,371 - 38,162 = X
293.209 = X
Thus, there are 293 liters and 209 milliliters of water left in the tank.
Jada walks up to a tank of water that can hold up to 10 gallons. When it is active, a drain empties
water from the tank at a constant rate. When Jada first sees the tank, it contains 7 gallons of water.
Three minutes later, the tank contains 5 gallons of water.
Type your answers in the boxes below.
C. How many minutes before Jada arrived was the water tank completely full?
Answer:
3 minutes and 30 seconds
Step-by-step explanation:
7-5 = 2
3/2 = 1.5 gallons that empty per each minute
1.5 times 3 (minutes) = 4.5 gallons emptied
Remaining gallons to empty = 0.5
0.5 gallons to empty will take 30 seconds

Answer:
A. Distance KL = 7.36 m
B. Height ML = 4.25 m
C. The maximum height is 6.96 m
Step-by-step explanation:
A. Determination of distance KL
Hypothenus = KM = 8.5 m
Angle θ = 30°
Adjacent = KL =?
Cos θ = Adjacent / Hypothenus
Cos 30 = KL / 8.5
0.866 = KL / 8.5
Cross multiply
KL = 0.866 × 8.5
KL = 7.36 m
Thus, the distance is 7.36 m
B. Determination of height (ML)
Hypothenus = KM = 8.5 m
Angle θ = 30°
Opposite = ML =?
Sine θ = Opposite /Hypothenus
Sine 30 = ML /8.5
0.5 = ML / 8.5
Cross multiply
ML = 0.5 × 8.5
ML = 4.25 m
Thus, the height is 4.25 m
C. Determination of the maximum height.
Hypothenus = KM = 8.5 m
Angle θ = 55°
Opposite = ML =?
Sine θ = Opposite /Hypothenus
Sine 55 = ML /8.5
0.8192 = ML / 8.5
Cross multiply
ML = 0.8192 × 8.5
ML = 6.96 m
Thus, the maximum height is 6.96 m

plz help oml
Answer:
5y-6
Step-by-step explanation:
the mathematical statement below are all linear inequalities in two variables EXCEPT:
a.)3y<10-2y
b.)2x-y>6
c.)3x-5y_>15
d.)23_<3m-2n
Answer: Option a: 3y < 10 - 2y
Step-by-step explanation:
A linear inequality is something that can be written as:
y > a*x + b
or
y < a*x + b
So we need to see which inequality of the given ones CAN'T be written in this way.
a) 3*y < 10 - 2*y
Here we can see that we have only one variable, so this can not be a linear inequality.
b) 2*x - y > 6
We can rewrite this as:
y < -6 + 2*x
Then this is a linear inequality.
c) 3x-5y ≥ 15
This can be rewritten as:
y ≤ (3/5)*x - 15/5
Then this is a linear inequality.
d) 23 ≤ 3m - 2n
This can be rewritten as:
m ≥ (2/3)*b + 23/3
This is a linear inequality.
Then the option that is not a linear inequality in two variables is option a.
