- 1 <= sin (a) <= 1

-2+5*(-1)<= -2+5sin(pi/12)(x-2)<= -2 +5*(1)

the minimum value of y is

y = - 2 + 5 * ( - 1 ) = - 7

hope this would help you

Answer:

$\Large \boxed{-7}$

Step-by-step explanation:

We can find the minimum of the function by plotting the function on the graph.

$\displaystyle \mathrm{y=-2+5 \cdot sin(\frac{\pi }{12}(x-2) )}$

The minimum value is the y value of the lowest point on the graph.

Evaluate the exponential expression: (2x)2nd power −3y2nd power =___, if x = 5 and y = 3.

ANSWER

A. 73

EXPLANATION

The given expression is

$(2{x})^{2} - 3{y}^{2}$

We substitute x=5 and y=3 to obtain:

$(2 \times 5)^{2} - 3{(3)}^{2} = {10}^{2} - 3 \times 9$

This simplifies to,

$= 100 - 27$

$= 73$

The correct choice is A.

Find the value of x. Picture below

Wittaler [7]

Here a right angled triangle given. We know that one angle of a right angled triangle is 90°.

As the sum of three angles of a triangle is 180°, so we can say the sum of other two angles of a right angled triangle is (180-90)° = 90°.

Here in the figure the other two angles given $(2x)^o$ and $(x+15)^o$ . Sum of these two angles is 90°.

So we can write the equation as,

$(2x)+(x+15) = 90$

We have to remove the parenthesis now.

$2x+x+15 = 90$

Now we will add the like terms. Here x and 2x are like terms. By adding them we will get,

$3x+15 = 90$

To solve it for x, now we have to move 15 to the other side by subtracting it from both sides.

$3x+15-15 = 90-15$

$3x= 90-15$

$3x= 75$

Now to get x, we have to move 3 to the other side, by dividing it to both sides.

$(3x)/3 = (75)/3$

$x = (75)/3$

$x = 25$

We have got the required value of x.

The solution is x= 25.

Please help and add explanation:)

Anni [7]

Answer:

Step-by-step explanation:

The above image shows two triangles. if we look at the top triangle, we notice it's two sides are equal (16 and 16). We therefore have an isosceles right triangle.

looking the second triangle, we notice that one side is 39, the other 40. Since these are the two sides joined at the point of intersection for the two images, and since 39 does not equal 40, the second triangle cannot be an isosceles right triangle. We conclude that the two triangles are not similar.

Which of the following is not an integer? 36 0 -22 0.75

Marta_Voda [28]

Answer:

$\Huge \boxed{\mathrm{0.75}}$

Step-by-step explanation:

Integers are whole numbers.

Integers include all negative and positive whole numbers. Zero is also included as an integer.

36 is a positive whole number. 36 is an integer.

0 is a whole number. 0 is an integer.

-22 is a negative whole number. -22 is an integer.

0.75 is not a whole number. 0.75 is not an integer.
