Step-by-step explanation:
First look at the 130. Since we know all these lines are straight, that means 130 and the angle adjacent to it is a supplementary angle. This means that you can take 180 and subtract 130 to get the inside angle. Now that you have two of three angles of the triangle, you can take 180 and subtract both of the known angles to get your final answer.

Andrew is creating a rectangular dog run in his back yard. The length of the dog run is 24 feet. The perimeter of the dog run must be at least 58 feet and no more than 96 feet. Use a compound inequality to find the range of values for the width of the dog run. Use
x when writing your inequality.
Answers
To find the range of values for the width of the dog run, we can set up a compound inequality using this formula:
2(24) + 2x ≥ 58 and 2(24) + 2x ≤ 96
Simplifying this, we get:
48 + 2x ≥ 58 and 48 + 2x ≤ 96
Subtracting 48 from each side:
2x ≥ 10 and 2x ≤ 48
Finally, dividing each side by 2:
x ≥ 5 and x ≤ 24
So the range of values for the width of the dog run is x ≥ 5 and x ≤ 24.

What is Sequences?Sequences in which the difference between succeeding terms is constant are known as arithmetic progressions. For instance, an arithmetic progression with a tolerance of 2 is the sequence 5, 7, 9, 11, 13, and so on. An arithmetic progression (A.P.) is a progression where the tolerance between two succeeding numbers is always the same. Arithmetic progression can be of two types: There are a finite number of terms in a finite geometric progression. The series' early, late, tolerance, and number of terms can be determined. Differential equations are frequently used in everyday life to compute the flow and motion of electricity, the back and forth motion of devices like pendulums, and to clarify thermodynamic principles.

Jina borrowed a total of $21,000 from two different banks to start a business. One bank charged the equivalent of 6% simple interest, and the other charged 3.5% interest. If the total interest after 1 year was $1210, determine the amount borrowed from each bank.
Answers
Answer: hope this helps
Let x be the amount borrowed from the bank that charged 6% interest and y be the amount borrowed from the bank that charged 3.5% interest. We know that:
x + y = 21,000 (the total amount borrowed)
We also know that the total interest after 1 year was $1210. The interest charged by the first bank is 6/100x = 0.06x and the interest charged by the second bank is 3.5/100y = 0.035y.
The total interest is the sum of the interest charged by both banks:
0.06x + 0.035y = 1210
We have two equations:
x + y = 21,000
0.06x + 0.035y = 1210
To find the amount borrowed from each bank, we can use the first equation to solve for one of the variables in terms of the other. For example, we can substitute y = 21,000 - x in the second equation:
0.06x + 0.035(21,000 - x) = 1210
0.06x + 735 - 0.035x = 1210
0.025x = 485
x = 19400
Now, we can substitute this value of x back into the first equation to find the value of y:
y = 21,000 - x
y = 21,000 - 19400
y = 1600
So, Jina borrowed $19400 from the bank that charged 6% interest, and $1600 from the bank that charged 3.5% interest.Step-by-step explanation:

Answer: final equation is g(x) = 5√x + 5
The parent function f(x) = √x is the square root function, which has a shape of a "V" upside down.
The first transformation is a vertical stretch by a factor of 5. To apply this transformation, we need to multiply the function by 5.
g(x) = 5√x
The second transformation is a translation 4 units right, which is the same as adding 4 to the x in the function.
g(x) = 5√x + 4
The final transformation is a translation 1 unit up, which is the same as adding 1 to the y in the function.
g(x) = 5√x + 4 + 1
So the final equation is g(x) = 5√x + 5
