Which function has a domain of all real numbers?
A. y = -2(3x)^1/6
B. y = (x +2)1/4
C.y = (2x)^1/3-7
D.y= -x^1/2+5
Answer:
c - (2x)^1/3-7
Step-by-step explanation:
plato
The function [tex]y= -x^{1/2}+5[/tex] has a domain of all real numbers.
Thus, option (D) is correct.
As, Domain is the input value of the function.
In the function [tex]y= -x^{1/2}+5[/tex] .
The square root is defined for all non-negative real numbers (including zero).
When we subtract this square root from 5, the resulting function has a domain of all real numbers.
In options A, B, and C, which involve fractional exponents or roots, option D does not have any restrictions on the values of x.
The function can be evaluated for any real number x, making its domain all real numbers.
Therefore, [tex]y= -x^{1/2}+5[/tex] , has a domain of all real numbers.

4. Emilio asks his classmates what month they were born. He finds that 15
out of 125 classmates were born in July. If there are 1,280 students in
Emilio's school, how many students can he expect to have birthdays in July
based on the experimental probability?
Ok
Answer:153
Step-by-step explanation:
From the question, we are informed that Emilio asks his classmates what month they were born and that he finds that 15 out of 125 classmates were born in July. This gives us a fraction of 15/125 = 3/25.
If there are 1,280 students in Emilio's school, the number of students that he can expect to have birthdays in July would be:
= 3/25 × 1280
= 153.6
There will be 153 students expected

Solve for g. If you can please add an explanation
Answer:
g=7
Step-by-step explanation:
your goal is to isolate the g
times g/-4 by -4/1 the -4 cancels out the other one so you are just left with g
move the g to the other side of the equation then move the 3 and it to the -5 and then multiply the whole thing but -1 to make the equation positive

At a store, a hat has a regular price of x dollars. During a sale, the price of the hat is discounted by 20%. The expression 0.8x describes the discounted price, in dollars, of the hat. Which expression also describes the discounted price, in dollars, of the hat?
Answer: D) x - 0.2x
Step-by-step explanation:
The hat has a regular price of x dollars.
This price is reduced by 20% so the relevant expression for the discount is; 20% * x or; 0.2x
The discounted price will be the price of the hat less the discount which means the formula will be;
= Price - discount
= x - 0.2x

How do geologists believe that the Devils Tower was formed?
A. All the land except the rocks around the Devils Tower were
eroded during the Ice Age.
B. The Devils Tower was an ancient hotspot that plate movements
isolated after the volcano became inactive.
C. Magma pushed up from the mantle to sedimentary rocks which
then eroded leaving the column.
D. It's the stem of a volcano that erupted millions of years ago
and surrounding rock eroded away.
Answer:
C. Magma pushed up from the mantle to sedimentary rocks which
then eroded leaving the column.
Step-by-step explanation:
Geologists Carpenter and Russell studied Devils Tower in the late 1800s and concluded that the Tower was formed by an igneous intrusion (the forcible entry of magma through other rock layers).

Answer:
1. no, 2. yes
Step-by-step explanation:
You need to use the triangular inequality thereom, which goes by if any side lengths are added together, they are greater than the remaining one. So, for number one, although 20+9=29>8 and 20+8=28>9, 9+8<20 since 9+8=17, which is less than 20. For number two, yes because 1) it is a right triangle triple and 2) 3+4=7>5, 4+5=9>3, and 5+3=8>4.
Answer:
Number 1 is Not a triangle so No and you don’t need to classify becuase it’s not aa triangle
Number 2 is a triangle becuase its ta Pythagorean triplet and even if you checK, it adds up.
Step-by-step explanation:
1) So using Pythagorean Theorem
8^2+9^2=20^2
64+91=400
That is not true
2) 3^2+4^2=5^2
9+16=25
That is true

what's the slope between (5,-2) and (-7,22)
Answer: The answer is: -2
Step-by-step explanation:
Here, suppose
(5,-2)=(x1, y1)
(-7,22)=(x2, y2)
Now, use the slope equation to find slope(m).
y2-y1=m(x2-x1)
or,m=y2-y1/x2-x1
After this, just substitute the values from above.
A map has the scale 0.75 of an inch equals 220 miles. The distance from Springfield to Glenview is 6 inches. How many actual miles separate Springfield from Glenview?
Answer:
1,760 actual miles separate Springfield from Glenview.
Step-by-step explanation:
Scaling
Objects can be represented in a reduced or augmented size by using scaling which is basically multiplying or dividing real dimensions by a constant factor. We use scaling when representing geographic locations on a map.
The map has the scale:
0.75 inch => 220 miles
This gives us the scaling factor as 220/0.75. There is no need to divide.
We are given the distance from Springfield to Glenview is 6 inches on the map. The actual distance is
6*220/0.75 = 1,760
1,760 actual miles separate Springfield from Glenview.
