Answer:
a.) -1 < x < 5
b.) x <= 1
Step-by-step explanation: Domain is the independent variable (x).
For both question a and b, make sure that the number under the square root does not end up being negative. And the denominator of the fractional number is not equal to zero when variable x is being substituted for any value.
a.) y = √ x + 1 /√ 25 − x^2
Domain : -1 < x < 5
That is the minimum value for x is 0 and the maximum value is 4
b. f(x) = (√ 1 − x ) ln x
Domain : x <= 1
That is, x is less than or equal to 1
The maximum value for x is 1. x can be
1, 0, -1, -2, -3, ..........
1% of 19,500= 195
6% = 1%x6 = 195x6 = 1170
19500+1170=20670
I found this --The first step to dividing fractions is to find the reciprocal (reverse the numerator and denominator) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. Finally, simplify the fractions if needed.
Nayeon and her aunt hiked 154 meters before they had lunch and after they had lunch, they hiked 84 more meters. all together they hiked 238 meters. The dad and sister hiked 167 meters before they had lunch and after they had lunch, they hiked 62 more meters. all together they hiked 329 meters. The difference in meters between Nayeon and her aunt and her dad and her sister (before lunch) is 13 meters.
Answer:
x=3
Step-by-step explanation:
7x(-3)=18
add 3 to both sides
7x=21
divide by 7 on both sides
x=3
