Answer:
37.8 %
Step-by-step explanation:
Let CP = 100
[tex]SP =\frac{100+profit}{100}*CP\\\\=\frac{120}{100}*100[/tex]
SP = 120
New CP:
CP decreased by 10%
[tex]Decreased \ amount=\frac{10}{100}*CP\\\\=\frac{10}{100}*100[/tex]
= 10
New CP = 100- 10 = 90
New SP:
SP increased by 10%
Increase amount = [tex]\frac{10}{100}*old \ SP[/tex]
[tex]= \frac{10}{100}*120\\\\= 12[/tex]
New SP = 120 + 12 = 132
Profit = new SP - new CP
= 132 - 90 = 42
Profit percentage = [tex]\frac{Profit}{CP}*100[/tex]
[tex]= \frac{42}{90}*100\\[/tex]
= 46.67%

Step-by-step explanation:
notice how in both diagrams, there are 4 triangles with lengths a, b, c, but in each diagram the triangles are just rotated and positioned differently. if there are the same amount of triangles in both diagrams, and the have equal lengths then the area of the remaining figure, should both match up.
basically the area of the big square in Step 2, is equal to both of the shaded squares, combined area, in Step 1.

in what interval is the function f(x)=squareroot x^2+5x+4 defined
9514 1404 393
Answer:
(-∞, -4] U [-1, ∞)
Step-by-step explanation:
The quadratic expression factors as ...
x^2 +5x +4 = (x +4)(x +1)
The zeros of this expression are where these factors are zero, at x=-4 and x=-1. The product is negative when one factor is negative and the other is positive, in the region -4 < x < -1. It is non-negative elsewhere. f(x) is defined where the quadratic is not negative, on the union of intervals ...
(-∞, -4] U [-1, ∞)
Answer:
-4 <= x >= -1
Step-by-step explanation:
Find where x^2+5x+4 < 0, negative sq roots are imagingary numbers.
So factor
(x + 4) (x + 1) = 0
x = -4 and x = -1
so x must be <= -4 or x >= -1
the interval is
-4 <= x >= -1

-2.06, .9803
.67, .7486
Step-by-step explanation:
1.)
To do this one you need to standardize x by subtracting the mean and dividng by the standard deviation
(1000-3262)/1100= -2.056 which i will round to -2.06
with this as our z value use the table to find the associated probability
.9803
2.)
Same process
(4000-3262)/1100=.67
which has a probability of .7486

Answer: The equation is [tex](x+4)^2 + (y-4)^2 = 9\\\\[/tex]
Center = (-4,4)
Radius = 3
===========================================================
Explanation:
This graph shows the circle's center is at (-4, 4)
Recall in general, the center is (h,k)
So we see that (h,k) = (-4,4). More specifically: h = -4 and k = 4.
The radius of this circle is r = 3 as this is the distance from the center to any point on the edge. For example, go from (-4,4) to (-1,4).
With the h, k and r values in mind, we then say the following:
[tex](x-h)^2 + (y-k)^2 = r^2\\\\(x-(-4))^2 + (y-4)^2 = 3^2\\\\(x+4)^2 + (y-4)^2 = 9\\\\[/tex]
which represents the equation of this circle.

A new site offers a subscription that costs 28.50 for 6 months.what is unit rate price per month? show ur work
Answer:
The answer is 4.75
Step-by-step explanation:
Since six months is 28.50 then 1 month is equal to x
28.50: 6 months
x : 1 month
After this you cross multiple so u divide by 6 both side to get 4.75
6x/6: 28.50/6
x=4.75

If the point (b,15) lies on the straight line with equation Y=5x fonde the value of b ?
Answer:
b = 3
Step-by-step explanation:
Substitute the y- coordinate 15 into the equation , that is
15 = 5x ( divide both sides by 5 )
3 = x
This is the x- coordinate of the point , so b = 3

After prime factorization of 56 we get 2 × 2 × 2 × 7
√(7×7×2×2×2)
7×2√2
14√2

[tex]3(x+2)2+4(x+2)+1=0\\[/tex]
Answer:
-3
-7/3
Step-by-step explanation:
Let u=x+2
We need to now solve 3u^2+4u+1=0 for u.
I'm going to try factoring. 3u (u)=3u^2 and 1(1)=1 so I'm going to try factored form (3u+1)(u+1).
Since 3u(1)+1(u)=4u, we are done.
Since (3u+1)(u+1)=0, then either 3u+1=0 or u+1=0.
Let's solve u+1=0 by subtracting 1 on both sides which obtains for us that u=-1.
Let's solve 3u+1=0 by subtracting 1 and then dividing both sides by 3 which obtains for us u=-1/3.
Since u=x+2, we are down to just solving the following:
x+2=-1 and x+2=-1/3
Both equations require us to subtract 2 on both sides.
The solutions are
x=-1-2=-3 and x=-1/3-2=-7/3
