Answer:
c 35%
Step-by-step explanation:
2 green,5 yellow, 6 red,and 7 blue marbles
2+5+6+7 = 20 marbles
P(blue) = blue marbles / total marbles
= 7/20
= 35/100
=35%
Answer:
The blue dot represents the absolute value of the number occupied by red dot.
Answer:
"f(x)
domain: all real numbers, range: all real numbers
f–1(x)
domain: all real numbers, range: all real numbers"
Step-by-step explanation:
We can use the fact that the domain of a function and the range of its inverse are equal.
Also, the range of the function and the domain of its inverse are equal as well.
<em>Looking at the function f(x/ = -x + 5, we see that this is a line with a negative slope of 1 and a y-intercept of +5. </em>
As we know from the graph of lines, there is no restricting values in x and y. So for the original function, domain is the set of all real numbers and the range is the set of all real numbers.
For the inverse, the range is set of all real numbers and domain is also the set of all real numbers.
First answer choice is right.
The picture in the attached figure
Let
h-------> <span>the planes height above ground level at the time of the bird strike
</span>
we know that
sin 7.7°=opposite side angle 7.7°/hypotenuse
where
opposite side angle 7.7°=h
hypotenuse=4 miles
so
sin 7.7°=h/4-------> h=4*sin 7.7°-----> h=0.54 miles
1 mile-----------> 5280 ft
0.54 mile------> x
x=0.54*5280-----> x=2829.79 ft------> 2830 ft
the answer is2830 ft
The third one if you try and solve that on a graph it will be harder.
5x-1 = 4x-8
-4x= -4x
x-1=-8
+1 = +1
X=-7
