$\text {Slope of AE = Slope of AC = } \dfrac{1}{2}$

$\text {Slope = } \dfrac{\text {change in y}}{\text {change in x}}$

$\dfrac{1}{2} = \dfrac{3}{AD}$

$AD = 3 \times 2$

$AD = 6 \text { unis}$

enyata [817]

Answer:

option A

Step-by-step explanation:

Let x be the number of television sold

and y be the number of computer sold

An electronics store makes a profit of $72 for every television sold and $90 for every computer sold.

Profit for x television is 72x

Profit of y computer is 90y

Total profit is 72x+90y

sales profit is atleast 360

so inequality becomes 72x+90y >360

graph is attached below

(5,2) lies on the shaded part, so (5,2) is our solution

(3,3) lies on the shaded part, so (3,3) is our solution

(1,4) lies on the shaded part, so (1,4) is our solution

(4,0) (2,2) (1,1) and (1,0) does not lies on the shaded part

So option A is correct

If the sin of angle x is 4/5 and the triangle was dilated to be two times big as the original, what would be the value of the di

Anon25 [30]

Given :

Sin x = 4/5

Using the rule of SOH CAH TOA,

we know that,

Sin x = opposite/Hypotenuse

So,

When the triangle is dilated, the opposite side will be dilated to 8 and the Hypotenuse will be dilated to to 10.

which means 4/5 will become 8/10

and hence,

8/10 after simplifying will be 4/5.Thus there is no change.

Hope this helped!

Brainliest is very much appreciated.
