An angle measured 10 degrees less than the measure of its complementary angle. Find the measure of both angles
Mazyrski [523]

Answer:

The measure of the angles are 40 degrees and 50 degrees

Step-by-step explanation:

Let

x ----> the measure of one angle in degrees

y ----> the measure of the complementary angle in degrees

we know that

If two angles are complementary, then their sum is equal to 90 degrees

so

x+y=90 ----> equation A

we have that

x=y-10 ----> equation B

Substitute equation B in equation A and solve for y

(y-10)+y=90\\2y-10=90\\2y=100\\y=50

Find the value of x

x=50-10=40

therefore

The measure of the angles are 40 degrees and 50 degrees

Is the given point interior , exterior, or on the circle k (x+2)2 + (y-3)2 =18 P (8,4)
Mnenie [13.5K]
One way would be to find the distance from the point to the center of the circle and compare it to the radius

for
(x-h)^2+(y-k)^2=r^2
the center is (h,k) and the radius is r

and the distance formula is
distance between (x_1,y_1) and (x_2,y_2) is
D=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}


r=radius
D=distance form (8,4) to center

if r>D, then (8,4) is inside the circle
if r=D, then (8,4) is on the circle
if r<D, then (8,4) is outside the circle


so
(x+2)^2+(y-3)^2=18
(x-(-2))^2+(y-3)^2=(\sqrt{18})^2
(x-(-2))^2+(y-3)^2=(3\sqrt{2})^2

the radius is 3\sqrt{2}
center is (-2,3)

find distance between (8,4) and (-2,3)

D=\sqrt{(8-(-2))^2+(4-3)^2}
D=\sqrt{(8+2)^2+(1)^2}
D=\sqrt{10^2+1}
D=\sqrt{100+1}
D=\sqrt{101}




r=3\sqrt{2}≈4.2
D=\sqrt{101}≈10.04

do r<D

(8,4) is outside the circle

Slope (-3,0 2,0 3,4 )
PtichkaEL [24]

Answer:

undefined

Step-by-step explanation:

so you can just pick 2 points. use -3,0, and 2,0. so to get from -3 to 2(becusse slope is change of y over change of x) you add 5. to get from 0 to 0, you would add zero. so, 5/0=undefined. I'm not quite sure why thered 3,4. in that case it may just not be a function

The service manager of a car dealer wants to determine if owners of new cars (A) tune up their cars more frequently than owners
ivann1987 [24]

Answer:

Null hypothesis: ∪ₐ = ∪ₓ

Alternative hypothesis: ∪ₐ ≠ ∪ₓ

Step-by-step explanation:

Null hypothesis: ∪ₐ = ∪ₓ

Alternative hypothesis: ∪ₐ ≠ ∪ₓ

where ∪ₐ represents mean of sample of new cars and ∪ₓ represents mean of sample of older cars.

Using a difference in means t test will help determine if new owners tune up their cars more frequently than older car owners.
