The graph of the function f(x)=V x+4 is shown below
The domain of the function is
Answers
Answer:
The function domain is:
{x|x ≥ -4}
Hence, option 4 is correct.
Step-by-step explanation:
Given the expression of the function
[tex]f\left(x\right)=\sqrt{x+4}[/tex]
We know that the domain of the function is the set of input values for which the function is real and defined
We know that the value inside the radical expression must be greater than or equal to 0 so that the function remains defined.
so
[tex]x+4\ge \:0[/tex]
subtract 4 from both sides
[tex]x+4-4\ge \:0-4[/tex]
simplify
[tex]x\ge \:-4[/tex]
Therefore, the function domain is:
{x|x ≥ -4}
Hence, option 4 is correct.

If a right triangle has sides of length 3 and 6, what is the length of the hypotenuse?
Answers
Answer:
Length of the hypotenuse = 3√5 units
Step-by-step explanation:
Given:
Right triangle sides
a = 3
b = 6
Find:
Length of the hypotenuse
Computation:
Length of the hypotenuse = √a² + b²
Length of the hypotenuse = √3² + 6²
Length of the hypotenuse = √9 + 36
Length of the hypotenuse = √45
Length of the hypotenuse = 3√5 units

A $270 suit is marked down by 20%. Find the sale price
Answers
Answer:
Marked down means the price has decreased by 20% so 100%-20%=80%
The suit is now 80% of its original price of 270.
So 270×(80/100)= 216
The selling price of the suit will be equal to $216.
What is the percentage?
The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that a $270 suit is marked down by 20%. The selling price will be calculated as,
Marked down means the price has decreased by 20%,
100%-20%=80%
The suit is now 80% of its original price of 270.

One mile is about 1.57 kilometers. If you are traveling at 55 miles per hour, what is the best estimate of your speed in kilometers per hour? A. between 50 and 60 kilometers per hour B. between 60 and 70 kilometers per hour C. between 70 and 80 kilometers per hour D. between 80 and 90 kilometers per hour
Answers
Explanation: All you have to do is multiply 1.57 x 55 (which equals 85.35). Not to be mean but all you have to do is read the answer carefully :)
why?
when you convert the speed from miles per hour to kilometers per hour we see it is equal to around 85 kilometers. this number falls right between the last options range of 80-90 km per hour

write a point-slope foem an equation of the line that passes through the given point and has the given slopes (2,-2); m = -5?
a. y -2 = -5(x -2)
b. y+2 = -5(x +2)
c. y -2= -5(x+2)
d. y +2= -5(x -2)
Answers
Answer:
y+2 = -5(x-2)
Step-by-step explanation:
The point slope form of a line is
y- y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line
y - -2 = -5(x-2)
y+2 = -5(x-2)
Yoshua borrowed $8,000 from his credit union over 9 months. He pays a simple interest of
9%. What is the total amount of money he will owe the bank?
Answers
Answer:
[tex]\boxed{\blue{\sf He\ will \ owe \ \$ 8540 .}}[/tex]
Step-by-step explanation:
According to Question , Yoshua borrowed $8,000 from his credit union over 9 months. He pays a simple interest of 9%. And we are required to find the total amount of money he will owe the bank .
So , we know the formula of Simple Interest as ,
[tex]\qquad\boxed{\red{\bf SI =\dfrac{P\times R\times T}{100}}}[/tex]
As ,per the data in Question ,
Amount = $ 8,000Time = 9 monthsRate of Interst = 9% .[tex]\implies SI = =\dfrac{P\times R\times T}{100} \\\\\implies SI =\dfrac{\$ 8000 \times \dfrac{9}{12}\times 9 }{100} \\\\\implies SI = \dfrac{\$ 8000 \times 9 \times 9 }{12\times 100 }\\\\\boxed{\pink{\bf \implies Simple\: Interst = \$ 540 }}[/tex]
Hence the Simple Interest is $ 540.
And , we know that Amount is ,
[tex]\qquad\boxed{\red{\bf Amount = SI + Principal}}[/tex]
[tex]\implies Amount = Principal + SI \\\\ \implies Amount = \$ 8000 + \$ 540 \\\\\boxed{\orange{\bf \implies Amount= \$ 8540 }}[/tex]
Hence he will owe $ 85400.

An 18 foot ladder rests against a wall. The base of the ladder is 8 feet from the wall. What angle does the
ladder make with the ground?
Answers
Answer:
The angle would be acute
Step-by-step explanation:
The angle that this ladder would make with the ground is equal to 63.64°.
How to determine the angle that the ladder make?In order to determine the angle that this ladder would make with the ground, we would apply Cosine trigonometric. Mathematically, this is given by this expression:
Cosθ = Adj/Hyp
Substituting the given parameters into the formula, we have;
Cosθ = 8/18
Cosθ = 0.4444
θ = cos⁻¹ (0.4444)

-2x + 17 = 11
What is x
Answers
Answer:
x=3
Step-by-step explanation:
Final Answer:
x = 3
Solution:
equation: -2x + 17 = 11
Step 1: subtract 17 in both sides
-2x + 17 = 11
-2x + 17 - 17 = 11 - 17
-2x = 11 - 7 (solve for -2x: 11 - 7)
-2x = -6
Step 2: divide -2 in both sides then solve for x.
-2x = -6
-2x -6
