Answer:
x = 3
Step-by-step explanation:
5.8x - 1.4 = 16 {add 1.4 to both sides}
5.8x = 16 + 1.4
5.8x = 17.4 {Divide both sides by 5.8}
x = 17.4/5.8
x = 3

at which points do the graphs of y= x+1 and y=2^2 intersection
The graphs of y = x + 1 and y = 2^x intersect at approximately (-0.3517, 0.6483) and (1.561, 3.561).
To find the points of intersection between the graphs of y = x + 1 and y = 2^x, we need to set the two equations equal to each other and solve for x.
Setting y = x + 1 equal to y = 2^x, we have:
x + 1 = 2^x
To solve this equation, we can use numerical methods or make observations to find the points of intersection. By observing the behavior of the two functions, we can see that they intersect at two points: one when x is negative, and another when x is positive.
For x < 0, the exponential function y = 2^x approaches 0 as x approaches negative infinity, while the linear function y = x + 1 continues to decrease as x becomes more negative. Thus, there is one point of intersection in this region.
For x > 0, the exponential function grows faster than the linear function, so there is another point of intersection in this region.
However, finding the exact values for the points of intersection requires numerical methods such as using a graphing calculator or solving the equation numerically. Approximate values for the points of intersection can be found as x ≈ -0.3517 and x ≈ 1.561.

What is 29% of 150?
Show work
Answer:
To find 29% of 150, we can first express 29% as a decimal by dividing 29 by 100. 29% is the same as 0.29.
Then, we multiply 0.29 by 150 to find the answer:
0.29 * 150 = 43.5
So, 29% of 150 is equal to 43.5.
Here's the work:

The upper-left coordinates on a rectangle are
(−4,4)
(4,4)
20 units.
Draw the rectangle on the coordinate plane below.
The rectangle has a length of 8 units along the top and bottom sides, and a height of 6 units along the vertical sides.
What is a rectangle?A rectangle is a four-sided flat shape with four right angles (90 degree angles) between the sides. It is a type of quadrilateral, which means a shape with four sides.
According to question:To find the length of the sides of the rectangle, we can use the distance formula:
d = √((x2 - x1)²+ (y2 - y1)²)
Using the coordinates (-4,4) and (4,4) for the two endpoints of the top side of the rectangle, we get:
d = √((4 - (-4))² + (4 - 4)²) = 8
Since the top side has length 8 and there are two top and two bottom sides of equal length, the perimeter is:
20 = 28 + 2L
where L is the length of one of the vertical sides. Solving for L, we get:
L = (20 - 2*8)/2 = 2
Therefore, the length of the vertical sides of the rectangle is 2 units.

The length of rectangle is 8 units on the x-axis, and the width of rectangle is 4 units along the y-axis.
What is a perimeter of rectangle?The whole distance encircling a rectangle's edge is known as its perimeter. It is the total of the measurements of the rectangle's four sides.
The formula for calculating the perimeter P of a rectangle with length L and width W is as follows:
P = 2L + 2W
According to question:
To find the length of the sides of the rectangle, we can use the distance formula:
\(d = \sqrt{((x_{2} - x_{1} )^2+ (y_{2} - y_{1})^2)}\)
Using the coordinates (-4, 4) and (4, 4)
\(d = \sqrt{((4 - (-4) )^2+ (4 - 4)^2)}\) = 8 units
L (length) = 8 Units
So, the length of the horizontal sides (x-axis) of the rectangle is 8 units.
then, the top side has length 8 and there are top and bottom sides are equal length, the perimeter is: P = (8+8) + 2W
20 = 16 + 2W
where, L is the length of one of the vertical sides. Solving for L, we get:
W = (20 - 16)/2 = 2
So, the length of the vertical sides (y-axis) of the rectangle is 2 units.

If the first term (a) is 4 and the common ratio (r) is 0.9, then the sequence diverges. Then the correct option is D.
What is a geometric sequence?Suppose the initial term of a geometric sequence is a
and the term by which we multiply the previous term to get the next term is r
Then the sequence would look like
a, ar, ar², ar³, ...
The sequence is given below.
\(\rm a_n = 4 (0.9)^n\)
Then the sum of the sequence will be given as
The first term (a) is 4. And the common ratio (r) is 0.9.
Then we get
\(\rm S_n = \dfrac{a (1 - r ^n)}{ (1 - r)}\\\\\rm S_n = \dfrac{4 (1 - 0.9 ^n)}{ (1 - 0.9)}\\\\\rm S_n = \dfrac{4 (1 - 0.9 ^n)}{0.1}\\\\\rm S_n = 40 (1 - 0.9^n)\)
For n = 1, we have
S₁ = 40 (1 - 0.9)
S₁ = 40 x 0.1
S₁ = 4
For n = 2, we have
S₂ = 40 (1 - 0.9²)
S₂ = 40 x 0.19
S₂ = 7.6
For n = 3, we have
S₃ = 40 (1 - 0.9³)
S₃ = 40 x 0.271
S₃ = 10.84

The integral to express the increase in the perimeter p(s) of a square when its side length s increases from 2 units to 5 units is:
p(s) = 4s
Integral = ∫2s5s ds
= ∫2s5s dx
= [s2/2]2s5s
= (25/2) - (4/2)
= 20/2
= 10
Therefore, the increase in the perimeter of the square when its side length s increases from 2 units to 5 units is 10 units.
To calculate this increase, we used the formula for the perimeter of a square, which is 4s, and the integral from 2s to 5s, which gives us the area under the graph and the difference between the two side lengths. We then solved for the integral and multiplied it by 4 to get the increase in the perimeter.
