Find the area of the figure.<br><br> plz i give brainliest.
Sonja [21]

Answer:

23.5 inches^2

Step-by-step explanation:

Area of triangle = 1/2 * base * height

area = 1/2 * (5+2) * (5+4)

area = 31.5 in^2

Area of rectangle = length * breadth

area = 4 * 2

area = 8 in^2

Area of figure = area of triangle - area of rectangle

area = 31.5 - 8

area =23.5 in^2

David kicks a soccer ball off the ground and in the air, with an initial velocity of 35 feet per second. Using the formula H(t)
sesenic [268]

Answer:

Step-by-step explanation:

The function for this problem is: h(t) = -16(t)^2 + vt + s h= the height t= time v= velocity s= starting height With the information given, we know that the starting height is 0, since it was from the ground, and the velocity of the ball is 35 feet per second. Inserting the these information into the equation, we get: h(t) = -16(t)^2 + 35t Now the question asks to find the maximum height. It can be done by using a grapher to graph the maximum of the parabola. It could also be done by finding the vertex, which would be the maximum, of the graph by using x= -b/(2a), where b is equal to 35 and a is equal to -16. We get x=35/32, the x-value of where the vertex lies. You can use this value as the t-value in the previous equation to find the h-value of the vertex. When you do, you get h= 19.1 feet, or answer D.

-3.2 + (-4.6) + 5.4 = ?? please show how you got your answer
Dovator [93]
-3.2+(-4.6)+5.4
when you add a negative number it is the same as just subtracting it.
-3.2-4.6+5.4
-3.2-4.6 can be done like this: -(3.2+4.6) making it -7.8
-7.8+5.4
-7.8+5.4 can be done like this -(7.8-5.4) making the final answer-2.4

Hope this helps :)
