Answer:

Correct option: 3

Step-by-step explanation:

When we have a crossing of two chords in a circle, there is a property that relates the angles in the intersection point and the arcs defined in the circle. From this property, we have that:

mAEC = (1/2) * (mAC + mBD)

Using the values of mAEC = 58° and mAC = 72°, we have that:

58 = (1/2) * (72 + mBD)

116 = 72 + mBD

mBD = 116 - 72

mBD = 44°

Correct option: 3

Answer:

$6.48

Step-by-step explanation:

First you divide do the $1.60 and the 10% discount which will bring you to $1.44 and then you times $1.44 and 4 1/2 to get $6.48.

Answer: £6.48

Step-by-step explanation:

1.6 after 10% discount = 1.44

For 4 1/2 pounds it is 1.44 x 4 1/2 =

6.48

the right answer is {3,4}

In case of intersection, we have to list the elements which are common in both sets.Here, 3 and 4 are present in both sets.

The discriminant is 76

Step-by-step explanation:

The equation needs to be in the form

ax^2 +bx +c =0

3x^2 - 6 = 2x

Subtract 2x from each side

3x^2 -2x - 6 = 0

The discriminant is

b^2 - 4ac

a = 3  b = -2  c = -6

Step-by-step explanation:

Answer: Yes

Step-by-step explanation:

In order to form a triangle, the sum of two sides must be GREATER than the third side.

a + b > c    &      a + c > b      &     b + c > a

5 + 2 > 4    &      5 + 4 > 2     &     4 + 2 > 6

Answer:

B: 48 cm^2

Step-by-step explanation:

Area of triangle= 1/2 bh

There are two triangles in the problem.

h = 8

b = 12

1/2 (12) (8) = 48 cm^2

Answer:

3 inches

Step-by-step explanation:

25*20*h=750

500h=750

h=1.5

Height*2 = length of one of the cut corners

1.5*2=3

Therefore, 3 inches

Answer:

5 in

Step-by-step explanation:

x = number of in cut from each side

V = 750

V=lwh

l = 25 -2x

w = 20-2x

h =x

V = (25-2x)(20-2x)x

(25-2x)(20-2x)x = 750

4x^3-90x^2+500x-750=0

Answer:

2 seconds

Step-by-step explanation:

1 minute 18 seconds is 78 seconds. 78 divided by 2 is 39, so it lost 2 seconds per day.

In 39 days we have 3369600 seconds in total

And according to question we lost, 1 minute and 18 seconds, i.e., in total 78 seconds

So, in 1-day the clock will be lost

= 78/39 seconds

= 2 seconds

pyramid with triangular base

The solid which is a triangular pyramid is A pyramid with triangular base.

A pyramid is a three dimensional solid shape which has a flat base which is polygonal in shape and it has a triangular flat lateral faces, which joins at a point called vertex.

There are many kinds of pyramids like triangular pyramid, square pyramid, right pyramid etc.

Triangular pyramid has the base of the pyramid in triang7ular shape.

So there will be three lateral triangular faces where each of them has one side on the base.

So a triangular pyramid has a triangular base.

Hence the triangular pyramid has a triangular base.

Answer:

The (single) solution is (1, 1).

Step-by-step explanation:

The second equation tells us that y = 6x-5.  Substitute this 6x - 5 into the first equation, as follows:  -x - 5(6x - 5) = -6

Then -x - 30x + 25 = -6.  Combining like terms, we get -31x = -31, so that x = 1.  Subbing this result into the second equation, we find y:  y = 6(1) - 5 = 1.  The solution is (1, 1).

your answer is C

x=

x/2

Step-by-step explanation:

If the function f(x)=2x then the inverse function is  f⁻¹(x) =x/2.

A relation is a function if it has only One y-value for each x-value.

The given function is f(x)=2x.

y=2x

Interchange the variables.

x=2y

Now solve for y

y=x/2

Replace y with f⁻¹(x) to show the final answer.

f⁻¹(x) =x/2

Hence, if the function f(x)=2x then the inverse function is  f⁻¹(x) =x/2.
