How do you do log 10 on a calculator?
To calculate log 10 on a calculator, you will typically use the "log" button. Depending on the type of calculator, you may need to enter the number 10 first, then hit the "log" button.
For example, if using a standard scientific calculator, you would enter 10, then hit the "log" button. On some calculators, you may need to hit the "10x" button first before hitting the "log" button. On some graphing calculators, you may need to use the "log base" button. When using this button, you would enter 10 as the base and the number you are trying to calculate the log of.
In some cases, you may need to use the "ln" (natural log) button instead of the "log" button. In this case, you would need to use the conversion formula of "ln x = 2.303 log 10 x" to get the desired number. Finally, some calculators may have an "antilog" button. This button will calculate the inverse of the logarithm or the power of 10 of a given number. To use this button, you would enter the number, then press the antilog button.

Find the slope of a line that passes through the given two points using ratio method
The slope formula, or the ratio of the change in the y values to the change in the x values, is m=(y2-y1)/(x2-x1).
What is slope ?A line's steepness and direction are measured by the line's slope.
Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all.
A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes.
The y coordinate's net change is y, and the x coordinate's net change is x.
Hence, The slope formula, or the ratio of the change in the y values to the change in the x values, is m=(y2-y1)/(x2-x1).

What will be the simplified form of 21b − 32 7b − 20b?
The simplified form of 21b − 32 7b − 20b would be 8b - 32.
Reducing an equation is a technique for rewriting it in a more straightforward format. Although some mathematical equations are not in the form of linear equations, they can be converted into linear equations by applying certain mathematical operations to them. These equations can be easily solved after being reduced to linear form, and the value of the unknown can be determined.
21b – 32 + 7b – 20b
= 21b + 7b – 20b – 32
= 28b – 20b – 32 = 8b – 32
21b - 32 + 7b - 20b

How do you find the third side?
The third side of a triangle can be found using the Pythagorean Theorem.
This states that the sum of the squares of the two shorter sides of a triangle must equal the square of the longest side (the hypotenuse).
Let's say you have a triangle with sides a, b, and c, where c is the longest side. To find c, you can use the following formula:
c = √(a2 + b2)
For example, if you have a triangle with sides a = 4 and b = 5, then c = √(42 + 52) = √41 = 6.4. Therefore, the third side of the triangle is 6.4.
To calculate this using steps, you would first square the two shorter sides of the triangle:
a2 = 4 x 4 = 16
b2 = 5 x 5 = 25
Then, add the two squares together:
16 + 25 = 41
Finally, take the square root of the sum to find the length of the third side:
√41 = 6.4
Therefore, the third side of the triangle is 6.4.

Mars has an angular size of approximately 8. 0 arcseconds as is 175,000,000 km away. Use S = r x a to figure out the diameter of Mars
The diameter of Mars is 6825 kilometers.
First we quantify angular size a = 8. 0 arcseconds in radians.
a = ( 8/ 3600) × (π/180)
a = 0.000039 radians
also, the distance from Earth to Mars in kilometres is 175,000,000 km
So, r = 175,000,000 km
We use the formula S = r x a to find the diameter of Mars
Substitute r = 175,000,000 and a = 0.000039 in above formula
S = 175,000,000 × 0.000039
S = 6825 km

The function h(x) = -x] is a transformation of the absolute value parent
function, f(x) = [x]. Which graph shows h(x)?
Answer:
b
Step-by-step explanation:
The graph that shows the function h(x) = -x] which is a transformation of the absolute value parent function, f(x) = [x] is Option C.
The graph of the function h(x) = -x] is the reflection of the graph of f(x) = [x] about the x-axis. The graph of f(x) is piecewise defined as follows:
f(x) = x, when x ≥ 0f(x) = -x, when x < 0The graph of h(x) will have the same shape as f(x), but with all the y-values negated, so:
h(x) = -x, when x ≥ 0h(x) = x, when x < 0The graph of h(x) will thus be a downward-facing step function, with steps at x = 0, moving from -x to x as x moves from negative to non-negative values. Thus, Option C is correct.

On Thursday, a local hamburger shop sold a combined total of 429 hamburgers and cheeseburgers. The number of cheeseburgers sold was two times the
number of hamburgers sold. How many hamburgers were sold on Thursday?
hamburgers
Let H be the number of hamburgers sold and C be the number of cheeseburgers sold.
The total number of hamburgers and cheeseburgers sold is given by the equation: H + C = 429
The number of cheeseburgers sold is given by the equation: C = 2H
Substituting the second equation into the first equation, we get: H + 2H = 429
Combining like terms, we get: 3H = 429
Dividing both sides by 3, we get: H = 143
On Thursday, 143 hamburgers were sold.
