Answer:
Step-by-step explanation:
Using law of indies;
√Xᵃ = Xᵃ/²
√(0.08¹²) = (0.08¹²ˣ¹/²)
= 0.08⁶
The correct answer is A; (0.08)⁶
For this case we must simplify the following expression:
[tex](\sqrt {0.08 ^ {12}}[/tex]
By definition of properties of powers and roots we have:
[tex]\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}[/tex]
So, we can rewrite the given expression as:
[tex]0.08 ^ {\frac {12} {2}} =\\(0.08) ^ 6[/tex]

Which graph shows the equation v = 4 +2t
Answer:
See attached picture
Step-by-step explanation:
This is a linear equation. To graph it, use the model y = mx + b where m is the slope and b is the y-intercept. Here m = 2 and b = 4. Start at the point (0,4) on the y-axis. Mark this point because it is the y-intercept. Then move up 2 units and over 1 to the point (1, 6). Mark this point. And connect. This is the correct graph. See attached picture.
the height of a triangle is twice the length of its base. The area of the triangle is 50 m^2. Find the height and base to the nearest tenth of a meter
Answer:
base = 7.1 m and height = 14.2 mStep-by-step explanation:
The formual fo ana area of a triangle:
[tex]A=\dfrac{bh}{2}[/tex]
b - base
h - height
We have A = 50 cm² and h = 2b. Substitute:
[tex]\dfrac{(b)(2b)}{2}=50\\\\b^2=50\to b=\sqrt{50}\ m\to b\approx7.1\ m\\\\h=2b\to h=2(7.1)=14.2\ m[/tex]
To find the height and base of the triangle with an area of [tex]50 m^2[/tex]and the height being twice the base, we use the area formula[tex]A = (base imes height) / 2,[/tex] solve for the base, and double it to find the height. The base is approximately 7.1 m, and the height is approximately 14.1 m.
The question seeks the height and base of a triangle whose area is 50 [tex]m^{2}[/tex] and the height is twice the length of its base. The area of a triangle can be calculated using the formula A = [tex](base imes height) / 2.[/tex] Since the height is twice the base, we can say the height is 2b, where b is the base.
Plugging into the formula for the area of a triangle, we get:
Area, A = 50 m2
[tex]A = (b imes 2b) / 2[/tex]
50 = b2
b = \/50
b \/= 7.1 m (to the nearest tenth)
[tex]Height (h) = 2 imes b = 2 imes 7.1 m[/tex]
h = 14.1 m (to the nearest tenth)
Therefore, the base of the triangle is approximately 7.1 m and the height is approximately 14.1 m.

kristy ran 24 laps in chairity run and then walked 0.2 kilometer to the presentation table. The total distance Kristy traveled was 29.6 kilometers. What was the distance of each lap? Explain how you solved the problem.
total distance of 24 laps
29.6km - 0.2km
=29.4km
total distance of each lap
24 laps = 29.4km
1 lap = ?
Use cross-multiple
24 laps × X = 29.4km × 1 lap
X = 29.4km / 24
X = 1.225km
Answer
1.225km
Answer:
1.225km is equal to each laps
Step-by-step explanation:
Since Kristy total distance traveled = 29.6km
And Kristy ran 24 laps and later walk 0.2km. it simply implies that
Total distance traveled = distance covered running + distance covered walking
Since we know that
Total distance traveled = 29.6km
distance covered running = 24 laps
distance covered walking = 0.2km
Distance covered running in km = total distance traveled - distance covered walking
Distance covered running in km = 29.6km - 0.2km = 29.4km.
To now find the distance for each lap.
Since we have:
Distance covered running in km = 29.4km.
Distance covered running in lap = 24 laps
i.e
24 laps = 29.4km
1 lap = x
Use cross-multiple
24 laps * x = 29.4km × 1 lap
x = 29.4km / 24
x = 1.225km
Therefore
1.225km is equal to each laps.

What is the area in terms of pi
Answer:
C = 70π cmA = 2,450 cm²Step-by-step explanation:
The perimeter of the given figure is equal to the circumference of whole circle.
The formula of a circumference of a circle:
[tex]C=\pi d[/tex]
d - diameter
We have d = 70 cm. Substitute:
[tex]C=70\pi\ cm[/tex]
The area of given figure is equal to the area of rectangle 70cm × 35cm.
(look at the picture).
The area of a rectangle:
[tex]A=(70)(35)=2,450\ cm^2[/tex]
The area of a circle is given by the formula A = πr², where π represents pi, and r the radius. The area can be left in terms of pi to avoid rounding errors, with the example of a circle with 1.2-meter radius having an area of approximately 4.5 m² when considering significant figures.
The area of a circle is expressed as A = πr², where π (pi) is approximately 3.14159265, and r is the radius of the circle. In terms of pi, this formula is often left in the form of πr² to retain the exact value without rounding. For example, if we have a circle with a radius of 1.2 meters, the area would be calculated as A = π(1.2 m)² = 4.5238934 m² using a calculator with eight-digit precision. However, since the radius is given with two significant figures, the appropriate representation of the area would be A=4.5 m².
It is important to note that when expressing the area in terms of pi, you may encounter different contexts such as finding the area of a semicircle using the definite integral that results in r²/2 for the semicircle's area, or understanding proportionalities in a circle divided into slices.

The height of the tree is 23 meters
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
Let the height of the tree as 'x'.
The proportion can be set up as:
(height of the tree) / (length of the tree's shadow) = (height of the building) / (length of the building's shadow)
Plugging in the given values:
x / 9 = 54 / 21
To solve for x, we can cross-multiply:
21x = 54×9
21x = 486
Dividing both sides by 21:
x = 486 / 21
= 23.143
Hence, the height of the tree is 23 meters.

a triangle garden is being formed with stones. the three sides measure 4 meters by 6 meters by 7 meters. which of the following is a true statement about the side of the triangle?
The true statement is the side lengths will form a triangle because 6+7>4. So option (d) is correct.
To determine if the given side lengths can form a triangle, we need to apply the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
Let's denote the side lengths as follows:
a = 4 meters
b = 6 meters
c = 7 meters
We'll check each possible combination:
1. \( a + b > c \): \( 4 + 6 > 7 \) (True)
2. \( a + c > b \): \( 4 + 7 > 6 \) (True)
3. \( b + c > a \): \( 6 + 7 > 4 \) (True)
Since all three conditions are true, the given side lengths (4, 6, 7 meters) can indeed form a triangle.
Thus, the correct option is D. The side lengths will form a triangle because 6 + 7 > 4.

What is the approximate area of the shaded region?
Answer:
At = 21.5 cm2
Step-by-step explanation:
At = Asqr - Acircle
At = A1 - A2
A1 = 10^2 = 100
A2 = Pi*(5)^2 = 78.5
At = 100 - 78.5
At = 21.5 cm2
Best regards
For this case we have that by definition:
The area of a circle is: [tex]A_ {c} = \pi * r ^ 2[/tex]
Where r is the radius of the circle.
The area of a square is: [tex]A_ {s} = l ^ 2[/tex]
Where l is the side of the square.
The area of the shaded region will be:
[tex]A_ {sr} = A {s} -A_ {c}[/tex]
So:
[tex]A_ {s} = 10 * 10\\A_ {s} = 100 \ cm ^ 2[/tex]
On the other hand:
[tex]A_ {c} = \pi * (\frac {10} {2}) ^ 2\\A_ {c} = \pi * 25\\A_ {c} = 78.5375cm ^ 2[/tex]
Finally:
[tex]A_ {sr} = 100-78.5375\\A_ {sr} = 21.4625[/tex]
Rounding out, we have that the area of the shaded region is 21.5 square centimeters.

in the function y= -1/2(x-1)^2+3, what effect does the negative sign have on the graph, as compared to the graph of y=x^2?
In the function y= -1/2(x-1)^2+3, the negative sign inverts the graph so that it opens downwards unlike y=x^2 that opens upwards. This is due to the negative slope which implies a descent in the graph when moving left to right, showing a negative correlation between x and y.
Explanation:In the function y= -1/2(x-1)^2+3, the negative sign in front of the fraction plays a vital role in the graph's orientation. Unlike the graph of y=x^2 which opens upwards, the negative sign causes the graph of the given function to open downwards. This occurs because the negative sign affects the slope of the function. Graphically, a negative slope means that as we move from left to right along the graph, it descends; showing a negative correlation between x and y. Thus in the concoction of a graph, when x increases, y decreases, or when x decreases, y increases. This is a fundamental rule in graphing quadratic functions.

The negative sign in the function [tex]y = -1/2(x-1)^2+3[/tex]inverts the graph compared to[tex]y = x^2[/tex], making the parabola open downwards and indicating a negative relationship between the x and y values.
The negative sign in the function [tex]y = -1/2(x-1)^2+3[/tex] in comparison to the function [tex]y = x^2[/tex]inverts the graph of the parabola. While the graph of[tex]y = x^2[/tex]opens upwards, the negative coefficient causes the graph of the given function to open downwards. This means that instead of the parabola having a minimum point which occurs in [tex]y = x^2[/tex], the parabola will have a maximum point at the vertex (1, 3). As the x-value increases or decreases from the vertex, the y-value will decrease due to the negative sign, indicating that the two variables are negatively related. The general shape of the graph remains a parabola, but it is flipped vertically over the x-axis.

In the fifth grade there are 4/5 as many students who do not have glasses as those who do wear glasses if there are 60 students who wear glasses how many students are there in fifth grade
Answer:
300 students
Step-by-step explanation:
Since 4/5 of students do not wear glasses, 1/5 of students do.
There are 60 students who wear glasses, so let 'x' represent the number of students who wear glasses
(1/5)x = 60 is our equation. "One-fifth of the number of students who wear glasses is 60"
Now solve for x
(1/5)x = 60
x = 300 (multiply both sides by 5 to get rid of the fraction)
