Hello there!
This triangle is equilateral. Therefore, all the sides are equal.
We are given one of them. It is 12 units.
Therefore, all the other sides are 12 units long.
So a=12

How do you determine the domain of a function ?
Answer:
Let y = f(x) be a function with an independent variable x and a dependent variable y.
If a function f provides a way to successfully produce a single value y using for that purpose a value for x then that
chosen x-value is said to belong to the domain of f. If there is a requirement that a y-value produced by a function
must be a real number, the following conditions are commonly checked:
1. Denominators cannot equal 0.
2. Radicands (expressions under a radical symbol) of even roots (square roots, etc)
cannot have a negative value.
3. Logarithms can only be taken of positive values.
4. In word problems physical or other real-life restrictions might be imposed, e.g. time is
nonnegative, number of items is a nonnegative integer, etc.
Answer:
the domain is a set of all possible numbers inputs for that function, THe range is all the possible output numbers

STRUCTURE A quality control inspector at a bolt factory examines random bolts that come off the assembly line. All bolts being made must be a tolerance of 0.04 mm. The inspector is examining bolts that are to have a diameter of 6.5 mm.
From an absolute value inequality, we have that:
The minimum diameter is 6.46 mm.The maximum diameter is 6.54 mm.The absolute value measures the distance of a point or a function to the origin.One example of inequality is:[tex]|f(x)| \leq a[/tex]
Which has solution:
[tex]-a \leq f(x) \leq a[/tex]
In this problem:
Bolts with a diameter of 6.5 mm, with a tolerance of 0.04 mm, thus the absolute value of the difference of the diameter D and 6.5 has to be of at most 0.04, that is:[tex]|D - 6.5| \leq 0.04[/tex]
Applying the solution:
[tex]-0.04 \leq D - 6.5 \leq 0.04[/tex]
[tex]-0.04 \leq D - 6.5[/tex]
[tex]D - 6.5 \geq -0.04[/tex]
[tex]D \geq 6.46[/tex]
[tex]\leq D - 6.5 \leq 0.04[/tex]
[tex]D \leq 6.54[/tex]
The minimum diameter is 6.46 mm.The maximum diameter is 6.54 mm.A similar problem is given at https://brainly.com/question/24835634
javeria left home at 7:10, she walked for 15 mins to the station and walked for 10 mins for a train. she then travelled by train for 45 mins.
at what time did javeria get off the train?
a) 8:25
b) 8:20
c) 8:15
d) 8:10
Answer: Its B 8:20
Step-by-step explanation:
U get this by adding the 15 minutes to the 7:10 and then u get 7:25 then you add the 10 and u get 7:35 then you add the 45 and you get 8:20
The time at which Javeria gets off the train is 8:20 thus option (b) is correct.
What are work and time?Work is the completion of any task for example if you have done your homework in 5 hours then you have done 5 hours.
Another example of work is that if you have done your food by 1 hour it means your work duration is 1 hour so work is basically the time duration of any task which you have done.
As per the given,
Javeria left home at 7:10.
Add 15 + 10 + 45 = 70 minutes.
70 minutes = 1 hour + 10 minutes or 1:10
Add into 7:10 as
7 + 1:10 + 10
8:20
Hence "The time at which Javeria gets off the train is 8:20".

Which of the following describes the image of a triangle after a dilation that has a scale factor of 2/3?
A.-Each angle has 2/3 of the measure of its corresponding angle in the pre-image
B.-Each side has the same measure as its corresponding angle in the pre-image.
C.-Each angle has the same measure as its corresponding angle in the pre-image.
D.-Each side has 3/2 the length of its corresponding length in the pre-image.
We want to see which statement describes the image of a triangle after a dilation of scale factor of 2/3.
We will see that the correct option is C:
"Each angle has the same measure as its corresponding angle in the pre-image."
First, if we have a given figure and we apply a dilation of scale factor K, then all the measures of the given figures are affected by that dilation.
So if the 3 sides of the original triangle measured A, B, and C.
The new measures will be:
C' = k*CB' = k*BA' = k*ANotice that because all the sides changed proportionally, then the internal angles produced did not change after the dilation.
From this, we can conclude that the only correct option is C:
"Each angle has the same measure as its corresponding angle in the pre-image."
This says that the angles of the dilated triangle are the same ones as the angles of the initial triangle, which is true.

the side lenghts of a triangle are 14,15, and x units
9514 1404 393
Answer:
1 < x < 29
Step-by-step explanation:
The triangle inequality requires the sum of the two shortest sides exceed the longest side.
When x and 14 are the shortest:
x + 14 > 15
x > 1
When 14 and 15 are the shortest:
14 +15 > x
29 > x
Then the requirement for the length of x is ...
1 < x < 29
_____
Additional comment
The length of the third side of a triangle can be between the difference and sum of the two given sides.

4.The area of a garden is 12.9 square feet. Each square foot of the garden needs to have 2.6 pounds of soil.
How many pounds of soil are needed for the garden?
5. Multiply.
2.3⋅(−1.2)
a. −27.6
b. −2.76
c. 2.76
d. 27.6
Answer:
Step-by-step explanation:
1 =0.408
2=−30.004
3=−9.522
4= 33.54 pounds of soil are needed
5= b -2.76
1. Multiply (-6.8) * (-0.06) = 0.408
2. Multiply 11.54 * (-2.6) = -30.004
3. Multiply (-2.07) * (4.6) = -9.502
4. The garden needs 33.54 pounds of soil.
5. Multiply a). -27.6
When we multiply two numbers, we are essentially adding one of them multiple times based on the value of the other number. Let's go through each problem step by step.
1. To multiply -6.8 and -0.06, multiply their absolute values
(ignoring signs): 6.8 * 0.06 = 0.408.
Since both numbers are negative, the product is positive:
(-6.8) * (-0.06) = 0.408.
2. For 11.54 * (-2.6), multiply their absolute values:
11.54 * 2.6 = 30.004.
One number is negative, so the product is negative:
11.54 * (-2.6) = -30.004.
3. Multiply the absolute values of -2.07 and 4.6: 2.07 * 4.6 = 9.502.
The numbers have different signs, so the product is negative: (-2.07) * (4.6) = -9.502.
4. The area of the garden is 12.9 square feet, and each square foot requires 2.6 pounds of soil.
To find the total soil needed, multiply: 12.9 * 2.6 = 33.54. Therefore, the garden needs 33.54 pounds of soil.
5. To multiply 2.3 and -1.2, multiply their absolute values: 2.3 * 1.2 = 2.76. Since one number is negative, the product is negative: 2.3 * (-1.2) = -2.76, which matches option a.)

Use Quadratic equation to solve
a2 -4a - 4 = 0
Answer:
a = 2 ± 2[tex]\sqrt{2}[/tex]
Step-by-step explanation:
a = 1
b = -4
c = -4
x = (-b ± [tex]\sqrt{b^2 - 4ac}[/tex]) / 2a
x = (-(-4) ± [tex]\sqrt{(-4)^2-4(1)(-4)}[/tex]) / 2(1)
x = (4 ± [tex]\sqrt{16 +16}[/tex]) / 2
x = (4 ± 4[tex]\sqrt{2}[/tex]) / 2
x = 2 ± 2[tex]\sqrt{2}[/tex]

Answer:
18/24 or 75%
Step-by-step explanation:
Okay so you already know that he got 16/24 which means that there were 8 questions that were wrong because 24-16= 8
So he has 16 points that we know of and 8 questions that he got wrong.
If he lost 1/4 of a point when he got it incorrect 1/4= 0.25
0.25 x 8 = 2points
So he got to points
16+ 2= 18 so now it is 18/24
If you have to show Out for 100% it would be 75%

Solve z=sh/s+h for s
Answer:
[tex]\displaystyle s = \frac{hz}{h-z}[/tex]
Step-by-step explanation:
We are given the equation:
[tex]\displaystyle z = \frac{sh}{s+h}[/tex]
And we want to solve it for s.
First, we can multiply both sides by the denominator:
[tex]\displaystyle z(s+h) = sh[/tex]
Distribute:
[tex]\displaystyle sz + hz = sh[/tex]
Subtract hz and sh from both sides:
[tex]\displaystyle sz - sh = -hz[/tex]
Factor:
[tex]\displaystyle s(z-h) = -hz[/tex]
And divide. Hence:
[tex]\displaystyle s = \frac{-hz}{z-h} = - \frac{hz}{z-h} = \frac{hz}{h-z}[/tex]
Any one of the above three forms are correct, although the third form is preferred because it omits the additional negative.

the angle measures of a triangle are in the ratio 5:6:7. find the angle measures of the triangle
Answer:
50°, 60°, 70°
Step-by-step explanation:
Sum the parts of the ratio, 5 + 6 + 7 = 18 parts
The 3 angles in a triangle sum to 180° , then
180° ÷ 18 = 10° ← value of 1 part of the ratio, then
5 parts = 5 × 10° = 50°
6 parts = 6 × 10° = 60°
7 parts = 7 × 10° = 70°
The angle measures of the triangle are 50° , 60° , 70°
