Answers
Using the laws of exponents to simplify the expression, we have; 5 1/3
What is an exponential expression?When the power of one or more terms of an expression is greater than 1, then the expression is in an exponential form. Thus some laws can be require to simplify an exponential expression.
In the given question,
2^7/ 2^5 + (4^5)^0 + 3^-1
Thus applying the division law of indices to the first term, we have;
2^7/ 2^5 = 2^(7 - 5)
= 2^2
In the second term, anything to the power of zero is 1. So that;
(4^5)^0 = (1024)^0
= 1
In the third term, applying the inverse law of indices. We have;
3^-1 = 1/ 3
Therefore,
2^7/ 2^5 + (4^5)^0 + 3^-1 = 2^2 + 1 + 1/3
= 4 + 1 + 1/3
= 5 + 1/3
= 16/ 3
= 5 1/3
The value of the expression is 5 1/3.

get an A. Let n represent the number of points Jose needs to score on the remaining tests.
The inequality is
+ n (select)
HELP ME WAAKAIAKAKAKAK
Answers
The inequality that represents the minimum number of points he must score on the remaining tests in order to get an A is 320 + n ≥ 389, n ≥ 69, where n is the number of points.
When we use ≥ symbol, as at least means greater than or equal to.
320 + n ≥ 389
Subtracting 320 on both the sides,
n ≥ 69,
n represents the score he must receive on the remaining tests. Then n + 320 represents his total score for the semester.
Thus, the required inequality is n ≥ 69, which means that n is the minimum scored points to get A.

There are 50 bacteria present initially in a culture. In 3min., the count is 204800.
What is the doubling period?
Answers
Answer: The doubling period is the time it takes for the population of bacteria to double. To find the doubling period in this case, we need to determine how often the population doubles during the 3-minute period.
We know that the initial population is 50 and the final population is 204800, which means that the population has grown by a factor of 204800/50 = 4096. Since this is a multiplication by a factor of 4096, this means that the population has doubled 4096 times in 3 minutes.
To find the doubling period, we need to divide the total time (3 minutes) by the number of doublings (4096).
So, the doubling period is:
3 minutes / 4096 = 3/4096 minutes ≈ 0.0007 minutes ≈ 0.042 seconds
So, the population of bacteria doubles every 0.042 seconds

two side lengths of a triangle are 11 and 17. what is the longest possible integer length of the third side of the triangle?
Answers
Therefore, the potential length of a triangle's third side is 17-11<x<17+11 is equals to 6 < x< 28.
A triangle's third side must always have a length that falls between (but not exactly equal to) the sum and difference of the other two sides. Consider the examples 2, 6, and 7 as an example. The third side length must therefore be larger than 4 and less than 8.
According to the Triangle Inequality Theorem, any two triangle sides must add up to more than the third side's length. To find the potential length of a triangle, multiply the sum of the two sides by the difference of the two sides.
Therefore, the potential length of a triangle's third side is 17-11<x<17+11.

solve. 10) what are the dimensions of a right triangle with a 5 inch hypotenuse and an area of 6 square inches?
Answers
Answer:
The dimensions are 3, 4 and 5 inches.
Step-by-step explanation:
Area = 1/2 * height * base
6 = 1/2 * h * b
h * b = 12.
As the hypotenuse is 5 inches long
H^2 + B^2 = 5^2
From the third line: h = 12/b, so we have
(12/b)^2 + b^2 = 25
144/b^2 + b^2 = 25
144 + b^4 = 25b^2
b^4 - 25b^2 + 144 = 0
Let B = b^2, so
B^2 - 25B + 144 = 0
(B - 16)(B - 9) = 0
B = 16, 9
So, b = 4, 3
h = 12/b
= 3 , 4.

For the quadratic equation 2x² - 4x - 48 = 0 value of x is 6 and -4.
What is quadratic equation?
The second-degree equation is a quadratic equation. This indicates that it has at least one (1) squared phrase. Ax2 + bx + c = 0 is one of the most used formulas for solving quadratic equations. Here, a, b, and c are constants or numerical coefficients. Here, the variable "X" is unknowable.
ax^2 + bx + c = 0 is a quadratic equation, which is a second-order polynomial equation in a single variable. a 0. It has at least one solution because it is a second-order polynomial equation, which is guaranteed by the algebraic fundamental theorem. The answer could be simple or complicated.
We have a quadratic equation;
2x² - 4x - 48 = 0
To find the value of x we have to follow these steps ;
(2x^2 - 4x) - 48 = 0
Pull out like factors :
2x^2 - 4x - 48 = 2 • (x^2 - 2x - 24)
x2 multiplied by 2x and 24
x^2 is the initial term, and it has a coefficient of 1.
The coefficient of the middle term, which is -2x, is 2.
"The constant," the final term, is -24.
⇒ x^2 - 6x + 4x - 24
⇒ (x+4) • (x-6)
⇒ 2 • (x + 4) • (x - 6) = 0
therefore x+4 = 0
x = -4
and x-6 = 0
Add 6 to both sides of the equation :
x = 6
Hence, for the quadratic equation 2x² - 4x - 48 = 0 value of x is 6 and -4.

What is a reflex angle?A reflex angle is a type whose value falls within 180^o and 360^o. This implies that the value of the angle is greater than 180^o, but less than 360^o.
Considering the reflex angle given in the question, it can be deduced that;
m<AGE + m<GAE + m<GEA = 180^o
But,
i. m<GAB + m<GAE = 180^o (sum of angles on a straight line)
120 + m<GAE = 180
m<GAE = 180 - 120
= 60
m<GAE = 60^o
ii. m<GEA + m<GEL = 180^o
m<GEA + 80 = 180
m<GEA = 180 - 80
= 100
m<GEA = 100^o
Thus,
m<AGE + m<GAE + m<GEA = 180^o
m<AGE + 100 + 60 = 180
m<AGE = 180 - 160
= 20
m<AGE = 20^o
Therefore,
x + m<AGE = 360 (sum of angles at a point)
x + 20 = 360
x = 360 - 20
= 340
x = 340^o

Answers
The following type of study can be concluded as an observational study.
An observational study is a type of study that is used to gather data on the characteristics and behaviors of a particular group of people or subjects without actively manipulating or interfering with the subjects.
This study can be used to suggest a causal relationship between increased stress and muscle cramps, but it cannot conclusively prove causality.
There are several reasons why this study design cannot be used to conclude a causal relationship. First, the study is a non-randomized, uncontrolled experiment, which means that there may be other factors that could be influencing the results.
For example, the subjects in the stress group may have other characteristics or preexisting conditions that are related to muscle cramps. Additionally, the study does not have a control group for comparison, so it is not possible to determine if the muscle cramps are caused by stress or by some other factor.
Second, the study design is a single-blind study, which means that only the subjects are not aware of their group assignment, but the experimenter knows which group the subjects are in. This can lead to bias in data collection, analysis, or interpretation.
Therefore, The following type of study can be concluded as an observational study.

What is a circle?
A circle is a special kind of ellipse in which the eccentricity is zero and the two foci are coincident. A circle is also termed as the locus of the points drawn at an equidistant from the center. The distance from the center of the circle to the outer line is its radius. Diameter is the line which divides the circle into two equal parts and is also equal to twice of the radius.
The equation of circle in the plane is given as:
(x-h)^2 + (y-k)^2 = r^2
where (x, y) are the coordinate points
(h, k) is the coordinate of the center of a circle
and r is the radius of a circle.
and Area of circle = πr²
Now,
Area of the shaded region=area of large semicircle-2*area of small semicircles
radius for large semicircle=7cm
radius for small semicircle=3.5cm
Therefore,
Area of the shaded region=πR^2-2*πr^2
