The domain of the function y = √(x+7) + 5 is [-7, ∞).
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
The given equation is y = √(x+7) + 5.
For the expression under the square root to be non-negative, we must have x + 7 ≥ 0.
The domain of the function is all real numbers greater than or equal to -7.
Thus,
The domain of the function y = √(x+7) + 5 is [-7, ∞).

Anita typed 390 words in 6 minutes. At the rate, how many words can she type in 10 minutes?
Answer:
She can type 650 words in 10 minutes.
Step-by-step explanation:
390 divided by 6 is 65. Anita types 65 words per min. 65 times 10 is 650. Therefore she types 650 words in 10 mins.
Answer:
650 words
Step-by-step explanation:
So you divide 390 by 6 so that you can figure out how many words she types per minute.
390/6= 65
So she types 65 words per minute,
Then you multiply 65 by 10 because thats how many minutes your trying to figure out.
65*10= 650
You have a summer job that pays time and half over time ( if you work more than 40 hours) after that is 1.5 times you hourly rate of $7.00/ hr.
Answer:
Step-by-step explanation:
Having a job that pays at $7 per hour is quite nice. And the question says that if he does overtime, he gets 1 and a half times the normal price of $7. This means that, for every overtime he works, he will get paid at
7 * 1.5 = $10.5
The question didn't state what, but if it's anything to go by the wages expected to be paid then I'd say the job isn't worth it if it's overly stressful. I said so because most jobs out there aren't really about the workers, but the money instead.

Find the volume of this prism. Its a triangular prism
Answer:
120 cm cubed
Step-by-step explanation:
first we need to find the size of the triangular face. we can do this by taking the height and with of the base, multiplying them, then dividing by two (3*8)/2
which gives us 12, so now we multiply by 10 to get the volume of the full prism. 12*10=120
Cierto tipo de mezcla contiene 5kg de arena y 3 kg de cemento: un constructor necesita 12 toneladas de esta mezcla. ¿qué cantidad se necesita de arena y de cemento?
Answer:
the sand and cement needed is 7.5 kg and 4.5 kg respectively
Step-by-step explanation:
The computation of the sand and cement needed is shown below:
Given that
The mix of sand and cement is 5kg and 3kg i.e. its ratio is 5:3
And there is a 12kg of mix of both things
So individually it required
For sand = 12 × 5 ÷ 8
= 7.5 kg
For cement = 12 × 3 ÷ 8
= 4.5 kg
Hence, the sand and cement needed is 7.5 kg and 4.5 kg respectively

Lilly wants to determine the association between her deposits and her savings account balance. She modeled the equation y = 75x + 100
for the line of best fit. The independent variable, x, is deposits and the dependent variable, y, is account balance. What does the y
intercept mean in this context?
A)
The starting savings account balance is $75.
B)
The starting savings account balance is $100.
The account balance increases by an additional $75 for
each deposit.
D)
The account balance increases by an additional $100 for
each deposit.
Answer:
D) The account balance increases by an additional $100 for each deposit
Step-by-step explanation:
The y intercept will always be the number being added or subtracted from the independent variable.
The y intercept of y = 75x + 100 is 100, it means that the starting savings account balance is $100.
What is a linear equation?A linear equation is in the form:
y = mx + b
Where m is the rate of change and b is the y intercept.
Given the equation:
y = 75x + 100
The y intercept is 100, it means that the starting savings account balance is $100.

solve by substitution
Answer:
x = − 3
Step-by-step explanation:
Let's solve your equation step-by-step.
− 2x − 4 = x + 5
Step 1: Subtract x from both sides.
− 2x − 4 − x = x + 5 − x
− 3x − 4 = 5
Step 2: Add 4 to both sides.
− 3x − 4 + 4 = 5 + 4
−3x = 9
Step 3: Divide both sides by -3.
−3x / −3 = 9 / −3
x = − 3

Explain how we know that the sine of 270 degrees is -1. State one other value of θ such that sinθ=1.
Solution :
Trigonometry is that branch of mathematics which is used to study the relationship between the angles and the lengths of the sides of a triangle.
We known that the co-ordinate of a point on the circumference of a circle making an angle θ with the horizontal having a unit radius is given by :
(1 cos θ, 1 sin θ).
And for any angle made by sin θ on the x - axis is 0 and on the y -axis is 1 or -1 depending on the quadrant.
Since, angle 270 degree falls on the 3rd quadrant, therefore, the value of the co-ordinates of the point is (cos θ, sin θ) = (0,-1).
So the value of sin 270° = -1.
One other example of sin θ = 1 is 90° as 90 degree falls in the first quadrant.
