The value of w(u(4)) is 73.
u( x ) = - 2*x + 2
w( x ) = 2*x^2 + 1
w( u( x ) ) = w( - 2*x + 2 )
⇒ w( u( x ) ) = 2*( - 2*x + 2 )^2 + 1
⇒ w( u( x ) ) = 2*[ 2^2 + ( 2*x )^2 - 2*2*( 2*x ) ] + 1
⇒ w( u( x ) ) = 2*[ 4 + 4*x^2 - 8*x ] + 1
⇒ w( u( x ) ) = 8 + 8*x^2 - 16*x + 1
⇒ w( u( x ) ) = 8*x^2 - 16*x + 9
⇒ w( u( 4 ) ) = 8*4^2 - 16*4 + 9
⇒ w( u( 4 ) ) = 8*16 - 16*4 + 9
⇒ w( u( 4 ) ) = 128 - 64 + 9
⇒ w( u( 4 ) ) = 73

How many points does a student need to score 70% on a 80 point test?
Answer: 56
Step-by-step explanation:
70÷100×80=56
Answer:
56
Step-by-step explanation:
Another way to write this question is "What percent of 80 is 70%."
So we would write a percent proportion:
x/80=70/100
To find x, we will do (80*70)/100 which is 5600/100 which is 56.
You could also use benchmark fractions:
10% of 80 is 8
10% * 7 = 70% so 8 * 7 also equals 70%
8 * 7 = 56
Hope this helped, let me know if you have any questions.

The length of a rectangle exceeds the breadth by 8 cm. Find the area of the rectangle, if its perimeter is 180 cm
Answer:
2009cm^2
Step-by-step explanation:
Given data
let the length be L
and the width be w
so
w= x
L=x+8
P= 180cm
P= 2L+2W
180= 2(x+8)+2(x)
180= 2x+16+2x
collect like terms
180= 4x+16
180-16= 4x
164= 4x
x= 164/4
x=41
W= 41cm
L= 41+8
L= 49cm
A= L*W
A=49*41
A=2009cm^2
Hence the area is 2009cm^2

the nearest tenth.
I milliliters
х
5
?
Answer:
44.1mm
Step-by-step explanation:
Given
Total solution of acis nad water = 329mm
Percentage that is acid = 13.4%
Amount that is acid = 13.4% of 329
Amount that is acid = = 13.4/100 * 329
Amount that is acid = 13.4*3.29
Amount that is acid = 44.086
Hence the amount of acids there is 44.1mm

The area of a triangle A is given as A =1/2 bh, where b is the base an h = height. (a) find h if A =30 and b=10
Answer:
h = 6
Step-by-step explanation:
Substitute the given to its corresponding places.
30 = [tex]\frac{1(10)h}{2}[/tex]
30 = 10h/2
Multiply both sides by two to remove the denominator.
2 [30 = 10h/2] 2
60 = 10h
Divide both sides by 10 to isolate h.
h = 6
To check, substitute everything to the original equation:
A = [tex]\frac{1(10)(6)}{2}[/tex]
A = 30 !
True or False? If one of the angles of a triangle is obtuse, then the triangle is obtuse.
Answer:
True
Step-by-step explanation:
Image result for True or False? If one of the angles of a triangle is obtuse, then the triangle is obtuse.
In an obtuse triangle, if one angle measures more than 90°, then the sum of the remaining two angles is less than 90°. Here, the triangle ABC is an obtuse triangle, as ∠A measures more than 90 degrees. ... Hence, if one angle of the triangle is obtuse, then the other two angles with always be acute.
Answer:
True, as long as the other angles are acute !!

Tom is playing at the opposite corner of the playing field to his friend . If the playing field is 180m wide and Tom is 300m away from his friend, how long is the playing field
Answer:
240 m
Step-by-step explanation:
we can picture this as a right triangle
(180)^2 + (l)^2 = (300)^2
300 would be the diagonal of the triangle since it is at the opposite corner
180 would be the height/leg of the triangle
