Answer:
The zeroes are: -3 and -2
Step-by-step explanation:
f(x) = x² + 5x + 6
This is the in the format...
ax² + bx + c
To find the zeroes of a function, you must find what two numbers that add to B but multiply to C. In this case, you have to find two numbers that add to 5 but multiply to 6.
The two numbers are...
3 + 2 = 5 (This is correct because the two numbers add are equal to B)
3 x 2 = 6 (This is correct because the two numbers multiplied together are equal to C)
You then know that you have ( x + 3 ) and ( x + 2 )
Please do not get confused, the answers ARE NOT 3 and 2. You have to set the zeroes equal to 0.
Here's what I mean by that...
x + 3 = 0
Subtract 3 on both sides...
x = -3
The other zero...
x + 2 = 0
Subtract 2 on both sides...
x = -2
Your answers are x = -2 and x = -3, make sure you always set your answers to zero.
Hope this helps!

Answer:
15 mph
Step-by-step explanation:
You need to find how much each side of the table is changing each time and change that into a fraction. In this example, the change in time is .5 hours. Repeat with the other side to get 12.5 miles. Next you change it into a fraction with the distance over the time to get 12.5/.5. Type this into the calculator to get the answer which is 15 mph.

find the unknown angles. QRT and SRV are congruent
Answer:
52
Step-by-step explanation:
so all of the angles added together will equal 180 and if angle qrt and angle srt are congruent then they are equal to each so first we subtract 76 from 180 and get 104. then we divide it by 2 because the two missing angles are congruent. 104/2=52 so h and j =52

No; a domain value has two range values.
Yes; there is only one domain value for each range value.
Yes; there is only one range value for each domain value.
No; a range value has two domain values.
Answer:
No; a domain value has two range values.
Step-by-step explanation:
Because domain value is the x value and range value is the y value. If the x value repeats then it is not a function.
Answer: I think the answer is letter A . "No; a domain value has two range values".
The Range is the difference between the lowest and highest values. Example: In {4, 6, 9, 3, 7} the lowest value is 3, and the highest is 9. So the range is 9 − 3 = 6.... The range of the function is the set of all values that f takes.
Since
x = − 1
produces
y = 9
and
y = 4 , the relation
( − 1 , 9 ) , ( 0 , − 1 ) , ( − 1 , 4 ) , ( 4 , 9 )
is not a function.
The relation is not a function.
Graph.

what is domain value
The value of a domain name is the price any person/entity/organization has to pay in order to purchase a name for their website. The costs can range from a one-digit number to 6- or 7-digit numbers, depending on the valuation factors. Your domain could be the name of the next big start-up or brand.... The domain of a function f(x) is the set of all values for which the function is defined
The domain is the set of all the values of

The length of a rectangle is 5m longer than its width. If the perimeter of the rectangle is 54m, find its length and width.
Answer:
Width=11
Length=16
Step-by-step explanation:
P=2L+2W
54=2(5+w)+2w
Open the brackets
10+2w+2w=54
10+4w=54
Collect the like terms
4w=54-10
4w/4w=44/4
W=11
Since the length is 5m longer
Therefore:11+5=16
Width=11
Length=16

The water level in a harbor is described by the function y = 7 cosine (pi x/6) + 25, where y represents the water level measured in feet, and x represents the number of hours since high tide. After approximately how many hours is the water expected to reach a depth of 28 feet the second time? Round to the nearest hour.
1 hour
2 hours
10 hours
12 hours
Answer:
10 hours
Step-by-step explanation:
The total number of hours the water is expected to reach a depth of 28 feet the second time is 2 hours and this can be determined by using the given data.
Given :
Function --- [tex]\rm y = 7cos\dfrac{\pi x}{6}+25[/tex]Where y represents the water level measured in feet, and x represents the number of hours since high tide.Substitute the value of y = 28 in the given function in order to determine the total number of hours water expected to reach a depth of 28 feet the second time.
[tex]\rm 28 = 7cos\dfrac{\pi x}{6}+25[/tex]
Subtract 25 on both sides in the above function.
[tex]\rm 3= 7cos\dfrac{\pi x}{6}[/tex]
Divide on both sides by 7 in the above expression.
[tex]\rm \dfrac{3}{7}= cos\dfrac{\pi x}{6}[/tex]
Further, simplify the above expression.
[tex]\rm 64.62= \dfrac{\pi x}{6}[/tex]
Cross multiply in the above expression.
[tex]\rm x = \dfrac{64.62\times 6 }{\pi}[/tex]
To convert into radian multiply the above expression by [tex]\pi/180[/tex].
[tex]\rm x = \dfrac{64.62\times 6 }{\pi}\times \dfrac{\pi}{180}[/tex]
x = 2.42 hours
x [tex]\approx[/tex] 2 hours (round off to the nearest hour)
