Answer:
174 ft²
Step-by-step explanation:
Assuming you're interested in the area of the figure, you can compute it as the sum of the areas of the triangle and rectangle.
The unknown side of the triangle can be figured from the overall dimension of the rectangle and the two lengths that are not part of the triangle base:
6 ft + triangle base + 6 ft = 18 ft
triangle base = 18 ft - 12 ft = 6 ft
Then the area of the triangle is ...
A = 1/2bh = 1/2(6 ft)(4 ft) = 12 ft²
__
Of course, the area of the rectangle is the product of its length and width:
A = LW = (18 ft)(9 ft) = 162 ft²
__
The total area of the figure is the sum of these:
area = triangle area + rectangle area
area = 12 ft² +162 ft²
area = 174 ft²
Are you looking for the value of x?
We can complete the square/factor:
x^2+7x-30=0
(x+10)(x-3)=0
By the zero product property rule, we have two equations, x+10=0 and x-3=0.
So the zeroes of x are -10 and 3
Hope this helped. Comment below if this didn't make sense.
Answer:
A) increases
Step-by-step explanation:
5/x + 5
suppose x = 5; then 5/5 + 5 = 1 + 5 = 6
x = 2; then 5/2 + 5 = 2.5 + 5 = 7.5
x = 1 ;then 5/1 + 5 = 5 + 5 = 10
So when x value decreases from a large positive number to a small positive number, 5/x + 5 increases
Answer:
Reminder that is this form a(b)^x where a > 0
When b > 0 but < 1 that is a decay function
When b > 1 than its a growth function
Step-by-step explanation:
So following this you can figure out the answer
g(x)=0.3(x)
this is neither since there is no exponent (linear)
H=72(56)^t
this is growth since b = 56
A=(43)^t
this is growth since b = 43 ("a" is understood as "1")
H=5.9(0.82)^t
this is decay since b = 0.82
y=0.8(3.6)^t
this is growth since b = 3.6
f(t)=0.72(15)^t
this is growth since b = 14
A=49(8)^t
this is growth since b = 8
