Answer:
51.08 in.²
Step-by-step explanation:
S.A = (l x b) + (l × h) + (b × h)
= (8.2 in. × 3.4 in.) + (8.2 in. × 2 in.) + (3.4 in. × 2 in.)
= 27.88 in.² + 16.4 in.² + 6.8 in.²
= 51.08 in.²
Answer:
The answer is 54.23489
Step-by-step explanation:
Hope this helps
Perimeter = (2*length) + (2*width)
326 = (2*length) + (2*75)
326 - 150 = 2*length
2*length = 176
length = 176 / 2
length = 88
So we see the leading coefient is positive (the 3 in the 3x^2 is positive) so the paraobola opens upward
so for it to have 2 x intercepts, we must have the vertex below the x axis
we must have the y value of the vertex negative
so
a hack is this
to move a function up c units, add c to whole function
also
for
y=ax^2+bx+c
the x value of the vertex is -b/2a
the y value is found by subsituting that value for x
so
y=3x^2+7x+m
x value of vertex is
-7/(2*3)=-7/6
if we sub it in
y=3(-7/6)^2+7(-7/6)+m
y=49/12-49/6+m
we want the y value to be less than 0
so
0>49/12-49/6+m
0>49/12-98/12+m
0>-49/12+m
49/12>m
so it will have 2 x intercept for all m such that m<49/12
Don’t mind the typed stuff at all. There’s your answer. g(x) =-5 you just plug in your given value to x
