Answer:
I think the answer is 5 ( if wrong then do a low rating)
Step-by-step explanation:
The way I found the answer was by using PEDMAS so first I handled [(4 - (-5)) x (-7)] which is the same as 4 + -5 which equals -1 and when multiplied by -7 equals positive 7 because whenever you multiply 2 negatives you get a positive.
Next I solved 6 / (-3) which is -2 since whenever a positive is divided by a negative the quotient is negative. Now the equation is:
-2 + 7 and when solved is -2 + 7 = 5
For the case of a line through
(
2
,
7
)
and
(
1
,
−
4
)
we have
slope
m
=
Δ
y
Δ
x
=

=

−

=

Using the point
(
2
,
7
)
we can write the equation of the line in point slope form as:
y
−
7
=
m
(
x
−
2
)
where the slope
m
=
11
.
That is:
y
−
7
=
11
(
x
−
2
)
To get point intercept form, first expand the right hand side so...
y
−
7
=
11
x
−
(
11
⋅
2
)
=
11
x
−
22
Then add
7
to both sides to get:
y
=
11
x
−
15
=
11
x
+
(
−
15
)
This is point intercept (
y
=
m
x
+
c
) form with slope
m
=
11
and intercept
c
=
−
15
.
Answer:
A. V = 1.936 cm^3
(or it could be C. V = 3.872 cm^3) **without the image, I can't be sure, but: if there are 2 congruent (identical) prisms, it might be asking for the entire volume, which would then be 2(1.936) = 3.872 cm^3
Step-by-step explanation:
I don't have the image shown, but the unit cm^3 means you're solving for volume. The formula is V = (1/2)wlh where width=w, length=l, h=height.
This simplifies to:
V = 1.936 cm^3
The radius is 8
Im not sure if this is what your looking for
