Number of parts = 1 + 4 = 5
Sum of all parts = $1000
Each part =
= 1000 ÷ 5
= $200
Money the man got =
= 200 × 1
= $200
Money the woman got =
= 200 × 4
= $800
The womans has $800 as her share .
Total parts = 2 + 1 + 1 = 4 parts
Sum of all parts = 800
Each part = 800 ÷ 4
Each part = 200
Then ,
The woman gets =
= 200 × 2
= $400
Her mother gets =
= 200 × 1
= $200
Her daughter gets =
= 200 × 1
= $200∴ Her daughter receives $200 .
Determine the range of the function.
y=1/4x^2 - 5
a.All real numbers.
b.All integers less than or equal to -5.
c.All integers greater than or equal to -5.
d.All real numbers greater than or equal to -5.
Answer:
[tex]Solution: f(x)\ge-5\\Interval:[-5,\infty)[/tex]
Step-by-step explanation:
Equation: [tex]\frac{1}{4} x^2-5 = y[/tex]
1). [tex]\frac{1}{4} x^2-5 = y[/tex] →[tex]\frac{x^2}{4}-5=y[/tex]
2). [tex]\frac{x^2}{4}-5=y[/tex] ∴ [tex]a=\frac{1}{4}, b=0, c=-5[/tex]
3). [tex]x_v=-\frac{b}{2a}[/tex]
[tex]=-\frac{0}{2(\frac{1}{4})}[/tex]
[tex]=0[/tex]
4). now plug [tex]x_v[/tex] into [tex]y_v[/tex]
[tex]y_v=\frac{0^2}{4}-5[/tex]
[tex]=-5[/tex]
5). Minimum (0,-5) ∴ [tex]f(x)\ge-5[/tex]

A class of 28 students has four more than two times as many
boys as girls. How many of the students are girls?
Answer:
there are 8 girl students
Step-by-step explanation:
28-4= 24
28 divided by 3 is 8
8x2=16
16+4=20
20+8= 28
therefore... there are 8 girls in the class
The width of a rectangle is 5 times the length. If the perimeter is 72, find the dimensions of the rectangle.
Answer:
l=6
b=30
Step-by-step explanation:
b=5l
perimeter= 72
2(l+b)= 72
l+b= 36
l+5l= 36
6l= 36
l= 6
b=5l= 6*6= 30

Step-by-step explanation:
All others have higher factors than 4
Answer:
B,(4,8) &C,(8,12)
Step-by-step explanation:
A,(2,4)=2=2
4=2^2(GCF of 2&4 is 2)
B,(4,8)=4=2^2
8=2^3(GCF of 4&8 is 4)
C,(8,12)=8=2^3
12=2^2*3(GCF of 8&12 is 4)
D,(8,16)=8=2^3
16=2^4(GCF of 8&16 is 8)
E,(12,24)=12=2^2*3
24=2^3*3(GCF of 12&24 is 12).

=======================================================
Explanation:
f(x) is continuous when x >= 1. The only discontinuity for f(x) is when x = 0, but 0 is not part of this interval.
f(x) is positive for any valid x value in the domain since x^6 is always positive. In general, x^n is positive for all x when n is any even number.
f(x) is decreasing. You can see this through a table of values or through a graph. For anything in the form 1/(x^k), it will be a decreasing function because x^k gets larger, so 1/(x^k) gets smaller, when x goes to infinity.
--------------------
The conditions to use the integral test have been met. So we have to see if [tex]\displaystyle \int_1^{\infty}f(x)dx[/tex] converges or not.
Let's integrate and find out
[tex]\displaystyle \int \frac{1}{x^6} dx = \int x^{-6} dx\\\\\\ \displaystyle \int \frac{1}{x^6} dx = \frac{1}{1+(-6)}x^{-6+1}+C\\\\\\ \displaystyle \int \frac{1}{x^6} dx = \frac{1}{-5}x^{-5}+C\\\\\\ \displaystyle \int \frac{1}{x^6} dx = -\frac{1}{5}*\frac{1}{x^5}+C\\\\\\ \displaystyle \int \frac{1}{x^6} dx = -\frac{1}{5x^5}+C\\\\[/tex]
So we have
[tex]\displaystyle g(x) = \int f(x) dx\\\\\\\displaystyle g(x) = \int \frac{1}{x^6} dx\\\\\\\displaystyle g(x) = -\frac{1}{5x^5}+C\\\\\\[/tex]
Meaning that,
[tex]\displaystyle \int_{a}^{b} f(x) dx = g(b)-g(a)\\\\\\\displaystyle \int_{a}^{b} \frac{1}{x^6} dx = \left(-\frac{1}{5b^5}+C\right)-\left(-\frac{1}{5a^5}+C\right)\\\\\\\displaystyle \int_{a}^{b} \frac{1}{x^6} dx = -\frac{1}{5b^5}+\frac{1}{5a^5}\\\\\\[/tex]
If we plug in a = 1 and apply the limit as b approaches positive infinity, then the expression [tex]-\frac{1}{5b^5}+\frac{1}{5a^5}[/tex] will turn into [tex]\frac{1}{5}[/tex]
Therefore,
[tex]\displaystyle \int_{1}^{\infty} \frac{1}{x^6} dx = \frac{1}{5}\\\\\\[/tex]
Because this integral converges, this means the series [tex]\displaystyle \sum_{n=1}^{\infty}\frac{1}{n^6}[/tex] also converges as well by the integral test.

What is X- y= 3 in a graph
Answer:
You must first put the equation into slope-intercept form (y = mx + b). To do this, subtract x from both sides to isolate y. Then, since y will be negative, divide each side by -1, resulting in y = x - 3. Since a 1 is understood to be in front of the x, the slope is 1
How to graph:
x-0 y- -3 or (0,-3)
x- 3 y-0 or (3,0)
