Step-by-step explanation:
The length of a rectangle is five time it’s width. If the perimeter of a rectangle is 84ft, find its area
Answer:
Area = 245 ft
(Width
Step-by-step explanation:
l = 5w
Where l is length and w is width.
We also know that the perimeter is 84 ft, so:
2l + 2w = 84
Now we can plug in 5w for l since we found the equality earlier:
2(5w) + 2w = 84
and then solve for w:
10w + 2w = 84
12w = 84
w = 7
so
l = 5 × 7
l = 35
The length is 35 and width is 7 so
the area of the rectangle is
[tex]7 \times 35 = 245ft [/tex]

Step-by-step explanation:
Reflect triangle ABC over the line y = 2.
Translate the image by the directed line segment from (0, 0) to (3, 2).
What are the coordinates of the vertices in the final image?
The question is an illustration of transformation, and the coordinates of the image of the triangle are (-3,7), (-2,4) and (0,6)
How to transform the triangle?The coordinates of the triangle are given as:
(-6,-1), (-5,2) and (-3,0)
When the triangle is reflected across the line y = 2 is, the new points are
(-6,5), (-5,2) and (-3,4)
Next, we translate the image of the triangle using the translation
(x,y) -> (x + 3, y +2)
So, we have:
(-6,5) => (-6 + 3, 5 + 2) = (-3,7)
(-5,2) => (-5 + 3, 2 + 2) = (-2,4)
(-3,4) => (-3 + 3, 4 + 2) = (0,6)
Hence, the coordinates of the image of the triangle are (-3,7), (-2,4) and (0,6)

2k+1 = 3k -2
k =3
every child has a 1 mom
f 7 = 3 f7= -6 this is imposible
[tex]\sf \boxed{\bold{k = 3}}[/tex]
Explanation:
If the first values of the two ordered pairs are the same, the relation is not a function.
Solve:
2k + 1 = 3k -2
2k - 3k = -2-1
-k = -3
k = 3
When k = 3, for the relation R= {(2k+1, 3), (3k-2, -6)} will not be a function.

Answer:
x=0 , x=-3
Step-by-step explanation:
Apply all exponent rules:
[tex]3^{x+3}[/tex] = [tex]3^{x}[/tex]×[tex]3^{3}[/tex]
[tex]\frac{1}{3^{x} }[/tex] = [tex](3^{x} )^{-1}[/tex]
Rewrite equation with [tex]3^{x}= u[/tex]
[tex]u[/tex] × [tex]3^{3}[/tex] + [tex]u^{-1}[/tex] - 28 = 0
Solve for u to give :
u = 1, u = 1/27
Substitute back u = [tex]3^{x}[/tex], solve for x :
[tex]3^{x}[/tex] = 1 , x= 0
[tex]3^{x}= \frac{1}{27}[/tex] , x= -3

2 in en 2x - In en 10x - In 30
x - 30
O x - 75
OX-150
X-300
Answer:
B
Step-by-step explanation:
Answer:
x=75
Step-by-step explanation:
2 * ln (e ^ ln (2x)) - ln (e ^ ln (10x)) = ln (30)
Apply exponent rules
2 * ln (2x) - ln (10x) = ln (30)
Apply log rules
2 * ln (2x) - ln (10x) = ln (30)
Apply log rule: logc(ab) = logc(a) +logc (b)
Apply exponent rules
2 * ln (2x) - ln (10x) = ln (30)
Apply log rules
2 * ln (2x) - ln (10x) = ln (30)
Apply log rule: logc(ab) = logc(a) + logc (b)
ln (2x) = ln (2) + ln (2)
2(ln (2) + ln (x)) - ln (10x) = ln (30)
Apply log rule: logc(ab) = logc(a) + logc (b)
ln (10x) = ln (10) + ln (x)
ln (2x) = ln (2) + ln (2)
2(ln (2) + ln (x)) - ln (10x) = ln (30)
Apply log rule: logc(ab) = logc(a) + logc (b)
ln (10x) = ln (10) + ln (x)
Apply log rule: logc(ab) = logc(a) + logc (b)
ln (10x) = ln (10) + ln (x)
2(ln(2)+ln(x))-(ln(10)+ln(x))=]
Expand 2(ln(2) +ln(x)
ln (x) + 2 * ln (2) - ln (10) = ln (30)
Subtract 2 * ln (2) - ln (10) from both sides
In(x) + 2ln(2) - In(10) - (2ln(2) - In
Simplify
ln (x) = ln (30) - 2 * ln (2) + ln (10)
Simplifify ln (30) - 2 * ln (2) + ln 10
ln (x) = ln (75)
Apply log rule: If logb(f(x)) = logb (g(x)) then f(x) = g(x)
x = 75
Verify Solutions: X = 75
Check the solutions by plugging them
into 2 * ln (2x) - ln (10x) = ln (30) Remove the ones that don't agree with the equation.
Plug in x =75
2 * ln (2 * 75) - ln (10 * 75) = ln (30)
2 * ln (2 * 75) - ln (10 * 75) = ln (30)
ln (30) = ln (30)

What is the arc measure of minor arc AB on circle P in degrees?
Answer:
74
Step-by-step explanation:
This is called a central angle, meaning that what ever te angle measure is, is the same to its ark measure.
So to find that inside angle measure you have to subtract 360 by 286
whitch is 74
74 is your inside angle and the angle for ark AB

x = 16

Angle1 = 80°
mAngle2 = 10°
Step-by-step explanation:
Angle 1 + Angle 2 adds up to 90°. The tiny square in the corner of the image shows you that the whole thing is 90°.
So write the equation base on that.
5x + x - 6 = 90
Combine like terms(add the x's)
6x - 6 = 90
Add 6.
6x = 96
Divide by 6.
x = 16
Fill in 16 for x to find the measures of the angles.
Angle 1 = 5x
= 5(16)
= 80°
Angle 2
= x - 6
= 16 -6
= 10°
And 80°+ 10° is 90° so that's a good check. Hope this helps!

In the diagram, a circle centered at the origin, a right triangle, and the Pythagorean theorem are used to derive the equation of a circle, x2 + y2 = r2.
If the center of the circle were moved from the origin to the point (h, k) and point P at (x, y) remains on the edge of the circle, which could represent the equation of the new circle?
A: (h + x)2 + (k + y)2 = r2
B: (x – h)2 + (y – k)2 = r2
C: (k + x)2 + (h + y)2 = r2
D: (x – k)2 + (y – h)2 = r2
Answer:
B
Step-by-step explanation:
[tex]\textsf{Let}\:(x_1,y_1)=(h,k)[/tex] → new center of the circle
[tex]\textsf{Let}\:(x_2,y_2)=(x,y)[/tex] → point on the circle
Therefore, the radius (r) is the distance between (x, y) and (h, k)
Use the distance formula:
[tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}=d[/tex]
[tex]\implies \sqrt{(x-h)^2+(y-k)^2}=r[/tex]
Square both sides:
[tex]\implies (x-h)^2+(y-k)=r^2[/tex]
Answer:
Option B
Step-by-step explanation:
Then we have to use distance formula to derive it
√(x-h)²+(y-k)²=r(x-h)²+(y-k)²=r²Option B is correct
