What is the area of the rectangle?

What is the area of the triangle?

Rectangle explanation:

If the Base and Height of the rectangle is 2, then we just have to multiply, and we get 4 as our answer.

Triangle explanation:

The area of the scalene triangle can be calculated using different formulas, Using base and height: (1/2) × base × height. Using Heron's formula: √s(s−a)(s−b)(s−c) s ( s − a ) ( s − b ) ( s − c ) , where where a, b, c are the sides and s is the semi-perimeter, s = (a + b + c)/2.

And I used just that formula to find my answer!

If you found my answer helpful, mark me brainliest! Have a great day!

You are buying shirts for an organization. You have $120 to spend. The number of short-sleeved shirts y you buy after buying x l

The given equation is ⇒ y = -1.2 x + 24

Part A : Graph the equation.

To graph the equation, substitute with values of x then find y

The attached figure represents the table to graph the equation and the graph of the equation.

=============================================

Part B : x-intercept

To find x-intercept substitute with y = 0 and solve for x

∴ 0 = -1.2 x + 24

∴ 1.2 x = 24

∴ x = 24/1.2 = 20

x-intercept is at point (20,0)

==================================================

Part C : y-intercept

To find y-intercept substitute with x = 0 and solve for y

∴ y = -1.2 * 0 + 24

∴ y = 24

∴ y-intercept is at point (0,24)

Determine the longest interval in which the given initialvalue problemis certainto have a unique twicedifferentiable solution. D

AlekseyPX

Answer:

t_o = 3, so solution exists on (0,4).

Step-by-step explanation:

Use Theorem

Divide equation with t(t — 4).

y''+[3/(t-4)]*y'+ [4/t(t-4)]*y=2/t(t-4)

p(t)=3/t-4—> continuous on (-∞, 4) and (4,∞)

q(t) = 4/t(t-4) —> continuous on (-∞,0), (0,4) and (4, ∞)

g(t) = 2/t(t-4)—> continuous on (-∞, 0), (0,4) and (4,∞)

t_o = 3, so solution exists on (0,4).

Your answer would be x = -15.8994.

To get this, you first add 7 to each side making the equation -4.818 = x/3.3

Then, you would need to multiply each side by 3.3 to get x by itself.

Your answer would be -15.8994.
