Answer:
Equation:
(5x)° + (x - 6)° = 90
OR
5x + x - 6 = 90
x = 16
m
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

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)

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]
Stephen bought a package of stickers for $0.50. His brother bought 4 times as many packages. How much did his brother spend? (3 points) a $2.00 b $2.25 c $2.50 d $3.00
a $2.00
Step-by-step explanation:
0.50 x 4 = 2
If he bought 4 times as many, then take the price times 4.
Answer:
$2.00
Step-by-step explanation:
Stephen bought 1 package for $0.50. His brother bought 4 times as many (4 * 1 packages). Which means his brother bought 4 packages.
If each package costs $0.50 then we simply multiply the price with the amount of packages he bought:
4 * $0.50. Lets get rid of the dollar sign, so it doesn't distract us.
I'm not sure if you studied about floating point numbers yet, but I assume you did.
4 * 0.50 =?
We have two numbers after the floating point, but for the sake of simplicity we can get rid of it too and just multiply 4 * 50 and then put the floating point back into the number after the first two digits (because we removed it after two digits 0.50)
Anyway 4 * 50 = 200
We add the floating point and get:
2.00
Therefore his brother spent $2.00 after we add the dollar sign back in

For what value of k will the relation R= {(2k+1, 3), (3k-2, -6)} not be a function?

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.

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)
True

Solve for u to give :
u = 1, u = 1/27
