Answer:
132 m².
Step-by-step explanation:
What's the surface area of each lateral face of this pyramid?
Each lateral face of this pyramid is a triangle, with
- a height of 8 meters
- on a base 6 meters.
The base of this pyramid is a square. As a result, all four lateral sides are congruent. The area of each of these triangle is thus
.
The base of this pyramid is a square. The length of a side of this square is 6 meters. The area of the base will be
.
Put the five faces together to get the total surface area of this square pyramid:
.
75.6%
78 - 19 = 59
59 / 78 = .75641
.75641 x 100 = 75.641
£18240
since the amount she earned falls within the range of the tax rate 40%, multiply her earnings by 0.4.
£45600*0.4= 18240
Answer:
a) f(-1/2) = -2 is NOT TRUE.
b) f(0) =3/2 is TRUE.
c) f(1) = -1 is NOT TRUE.
d) f(2) = 1 is NOT TRUE.
e) f(4) = 7/2 is TRUE.
Step-by-step explanation:
Here, the given function is 
Now, checking for each values for the given function:
a) Putting x = (-1/2):

and (5/4) ≠ -2
Hence, f(-1/2) = -2 is NOT TRUE.
b)Putting x = 0 :

Hence, f(0) =3/2 is TRUE.
c) Putting x = 1:

Hence, f(1) = -1 is NOT TRUE.
d)Putting x = 2:

and (5/2) ≠ 1
Hence, f(2) = 1 is NOT TRUE.
e)Putting x = 4:

Hence, f(4) = 7/2 is TRUE.
Answer:
a) true
Step-by-step explanation:
The bottom-line numbers from synthetic division <em>alternate signs</em>, indicating that -2 is a lower bound. The given statement is true.
__
If the signs were all positive, it would indicate the proposed zero is an <em>upper bound</em>.
__
A graph shows all real zeros are greater than -2.
