Answer:
1.58113883 i
Step-by-step explanation:
√-2.5 is error
1.58113883 i
i the square root of negative one.
Any number times itself is a positive number (or zero), so you can't ever get to a negative number by squaring. Since square roots undo squaring, negative numbers can't have square roots.
Answer:
[tex]1.58\ i[/tex]
Step-by-step explanation:
Step 1: Determine the square root of -2.5
The [tex]\sqrt{-1}[/tex] is equal to i so we can say that [tex]\sqrt{(-1)^2}[/tex] is equal to [tex]\sqrt{i^2}[/tex] which is then equal to [tex]i[/tex]. This means that we have [tex]i\sqrt{2.5}[/tex].
We can then take the square root of 2.5 which is rounded to [tex]1.58\ i[/tex]
Answer: [tex]1.58\ i[/tex]
3 burgers and 2 drinks cost $35.00
2 burgers and 1 drink cost $22.00
What is the cost of each item?
9514 1404 393
Answer:
burger: $9drink: $4Step-by-step explanation:
The two purchases can be described by ...
3b +2d = 35
2b +d = 22
Subtracting the first equation from twice the second, we get ...
2(2b +d) -(3b +2d) = 2(22) -(35)
b = 9 . . . . . . . . simplify
Then ...
2(9) +d = 22
d = 4 . . . . . . . . . subtract 18
A burger costs $9 and a drink costs $4.

1. How many triangles are created in the following situation:
Answer:
Step-by-step explanation:
We can use:
[tex]\frac{12}{sin35} = \frac{16}{sinB}[/tex]
Solve for sinB
[tex]sinB=\frac{16(sin35)}{12}[/tex]
The answer we get from that is: 0.76
With that answer, we can do:
[tex]B=sinx^{-1}(0.76)[/tex]
So, since the calculator did NOT put out an error, there is 2 such triangles.
Only 1 triangle can be formed by angle m∡A = 35°, a = 12, b = 16.
How many triangles are created in the following situation:m∡A = 35°, a = 12, b = 16. is to be determined.
The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should not be greater than 180°.
Here, the data given is m∡A = 35°, a = 12, b = 16,
Since one angle m∡A = 35° is given between the two sides a = 12, b = 16,.
There is only one triangle that can be made through the given data.
because when we plot the measures only one side can be added without calculation in order to complete the triangle.
Thus, only 1 triangle can be formed by m∡A = 35°, a = 12, b = 16.

What is the measurement of EF?
If necessary, round your answer to two decimal places, like this: 42.53
Answer:
EF = 1.98
Step-by-step explanation:
Sin = opposite/hypotenuse; Cos = adjacent/hypotenuse ;
Tan = opposite/adjacent
DF = 4.5 which is the hypotenuse. So using the equation for Sin
Sin 26° = opposite/hypotenuse
Sin 26° = EF/4.5
.44 = EF/4.5 solving .44(4.5) = EF ; 1.98 = EF

Answer:
Length = 34 yards
Width = 31 yards
Step-by-step explanation:
Perimeter = 2(l + w), where l = length, and w = width
We know that w, is l - 3
130 = 2(l + l - 3)
130 = 4l - 6
136 = 4l
l = 34
Width is 3 less than 34, or 31

Write each equation in slope-intercept form. Under line the slope and circle the y-intercept in each equation.
5x+3y=30
This is one RSM
The y-intercept is (_,_)
Answer:
y = -5/3(x) + 10
Step-by-step explanation:
Slope intercept form is in the form of y = mx + b
M is the slope and b is the y-intercept.
We want to isolate the y in this equation so we subtract both sides by 5x and get.
3y = -5x + 30
Now we can divide both sides by three to leave y by itself.
y = -5/3(x) + 10

Answer:
y = 1/7x -16/7
Step-by-step explanation:
We can point slope form
y-y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line
y - -2 = 1/7(x-2)
y+2 = 1/7(x-2)
Distribute
y+2 = 1/7x - 2/7
Subtract 2 from each side
y+2-2 = 1/7x -2/7-2
y = 1/7x -2/7 - 14/7
y = 1/7x -16/7

2t/t-5 + 1/t-3 = 3 Help..
Step-by-step explanation:
Given equation is 2t/(t-5) + 1/(t-3) = 3
=> [2t(t-3)+1(t-5)]/(t-5)(t-3) = 3
=> (2t²-6t+t-5)/(t²-5t-3t+15) = 3
=> (2t²-5t-5)/(t²-8t+15) = 3
=> 2t²-5t-5 = 3(t²-8t+15)
=> 2t²-5t-5 = 3t²-24t+45
=>3t²-24t+45-2t²+5t+5 = 0
=> t²-19t+50 = 0
The standard form is t²-19t+50 = 0

Charlotte buys a ticket to go to a baseball game. The total includes a charge of 7% of the original price for extra fees. If Charlotte pays a total of $44.94, how much was the original price of the ticket?
Answer:
$41.7942
Step-by-step explanation:
First you need to change 7% into a decimal (you do this by dividing it by 100)
7÷100=0.07
Then, you multiply 0.07 with 44.94
0.07×44.94=3.1458
3.1458 is the amount for the extra fees.
After that, you subtract 44.94 with 3.1458
44.94-3.1458=41.7942
This gives us the original price, so, the original price is $41.7942.
find the number which when divided by 2/5 will give 30
Answer:
The answer is 12. 12 divided by 2/5 will give us 30.
Step-by-step explanation:
To find this, simply do the opposite of dividing. Simply multiply 2/5 by 30, and you'll have your answer.
First, before we do this, however, we are going to find out what the decimal form of 2/5 is. To do this, divide the numerator by the denominator. In this case, 2 is the numerator and 5 is the denominator. So divide 2 by 5.
This gives us 0.4. So 2/5 in decimal form is 0.4. Now multiply 0.4 by 30 to find your answer.
30*0.4=12
So the answer is 12. However, rememeber that you always need to check your work. So lets check.
12/30=0.4
0.4=0.4
Do we get a true statement? Yes, so we are correct.
The number you are looking for is 75.
To find the number that, when divided by 2/5, gives 30, we can set up the following equation:
x / (2/5) = 30
To solve this equation, we can multiply both sides of the equation by the reciprocal of 2/5, which is 5/2:
x = 30(5/2)
Simplifying the right side of the equation:
x = 150/2
Dividing 150 by 2:
x = 75
Therefore, the number you are looking for is 75.
