Answer:
please stop being lazy by using OCR! next time type the question!
there's nothing such as = -x2 3x + 1
it's probablhy f(x) = -x² + 3x + 1
16+4(3q+p)
=16+4[3(-6)+2]
=16+4[-18+2]
=16+4[-16]
=16-64
= -48
Answer:
9.54 cm
Step-by-step explanation:
In triangle ABD, AD is the hypotenuse (longest side)
We know that according to Pythagoras theorem,
a^2+b^2=c^2
In the figure, c (10cm) and a (5cm) is given. So,
(5)^2 + b^2 = 100
25+b^2 = 100
b^2 = 75
So b is √75 = 8.66
Therefore BD is 8.66 cm
Now even BDC is a triangle
In it, the hypotenuse is missing but we know the value of other sides
so, in Pythagorean theorem,
a=4 (CD)
b=8.66 (BD)
c=x
Therefore,
(4)^2 + (8.66)^2 = x^2
16+74.99= x^2
x^2 = 90.99
x= 9.54 cm
Hope this helps!
Answer: 1.6, but if your looking for rounding numbers, its 2. I suggest 1.6 though.
Step-by-step explanation: hope this helps :)
Answer: 230
Step-by-step explanation:
Given: The amount earned by John in an hour= $5.75
If he worked 40.0 hours last week, then the amount he earned is given by:-
The amount he earned in 40 hours=
⇒The amount he earned in 40 hours= $230
Hence, he earned in 40 hours = $230
Therefore, the amount of his check was 230.
