d1i1m1o1n [39]

Answer:

2500

Step-by-step explanation:

let a represent the number of people that had swine flu on the 8th of May

a increased by 37.6% on the 9th of May. The 37.6% increase is equal to 3440

the equation that can be used to represent this is:

a x 1.376 = 3440

to find a, divide both sides by 1.376

a = 2500

In the figure CD is the perpendicular bisector of AB . If the length of AC is 2x and the length of BC is 3x - 5 . The value of x
Dennis_Churaev [7]

Answer

Find out the value of x .

To proof

SAS congurence property

In this property two sides and one angle of the two triangles are equal.

in the Δ ADC and ΔBDC

(1) CD = CD (common side of both the triangle)

(2) ∠CDA = ∠ CDB = 90 °

( ∠CDA +∠ CDB = 180 ° (Linear pair)

as given in the diagram

∠CDA  = 90°

∠ CDB = 180 ° - 90°

∠ CDB = 90°)

(3) AD = DB (as shown in the diagram)

Δ ADC ≅ ΔBDC

by using the SAS congurence property .

AC = BC

(Corresponding sides of the congurent triangle)

As given

the length of AC is 2x and the length of BC is 3x - 5 .

2x = 3x - 5

3x -2x =5

x = 5

The value of x is 5 .

Hence proved

Which equation can be simplified to find the inverse of y = 2x ^ 2 ?
Rama09 [41]

Answer:

D)x = 2y ^ 2

Step-by-step explanation:

y = 2x ^ 2

To find the inverse exchange x and y

x = 2 y^2

Then solve for y

Divide by 2

x/2 = 2y^2 /2

x/2 = y^2

Take the square root of each side

±sqrt(x/2) = y
