Answer: [tex]2 , -14[/tex]
Step-by-step explanation:
We know that the constant terms are the specific terms in an algebraic expression that have only numbers or numerical value or without any variable.
For example : The constant term in [tex]4x^2 -5m+16[/tex] is 16.
Let's take one more example , the constant term in [tex]3x-2y-4-7xy[/tex] is -4.
Given expression is : [tex]8m-5n+2+m-14[/tex]
Here, the terms are : [tex]8m,\ -5n,\ 2,\ m,\ -14[/tex]
Terms having variable = [tex]8m,\ -5n,\ m[/tex]
Terms without variable = [tex]2 , -14[/tex]
⇒ Constant terms =[tex]2 , -14[/tex]
Hence, the constant terms in the given expression = [tex]2 , -14[/tex]

Does the equation y = (0.9)x represents exponential growth or decay?Answer
Exponential Growth
Exponential Decay
Exponential decay is demonstrated in the equation y = (0.9)x, showcasing a decrease as x increases.
Exponential decay occurs when the base of the exponential function is between 0 and 1, causing the function to decrease as x increases.
For example, if x = 1, y = 0.9; if x = 2, y = 0.81; and so on.

If the numerator of a fraction is increased by 3, the fraction becomes 3/4. If the denominator is decreased by 7, the fraction becomes 1. Determine the original fraction.
Which of the following equations represents "If the numerator of a fraction is increased by 3, the fraction becomes 3/4"? (Hint: cross products)
Answer: 4n + 12 = 3d
Step-by-step explanation:
The equation representing "If the numerator of a fraction is increased by 3, the fraction becomes 3/4" is 4(x + 3) = 3y. This, alongside the second condition of the denominator decreased by 7 leading to the fraction becoming 1, provides two equations that can be solved for the original fraction.
Explanation:To represent the situation "If the numerator of a fraction is increased by 3, the fraction becomes 3/4," we can use the variable x for the numerator and y for the denominator of the original fraction. Therefore, the equation would be (x + 3)/y = 3/4. Applying the cross-product rule, we multiply each side of the fraction by the denominator on the other side, leading to 4(x + 3) = 3y. Simplified, this equation is 4x + 12 = 3y, which helps us solve for the original fraction along with the other given condition that reducing the denominator by 7 makes the fraction equal to 1. So, the second condition can be written as x/(y - 7) = 1. These two equations together can be solved simultaneously to find the values of x and y.

Sketch vectors A and B based on their descriptions. To find D = A - B, make B go in the opposite direction (namely, -B), put it tip to tail with A, and then vector D is from tail of A to tip of -B.
Explanation:To answer this, we need to sketch the two vectors - vector A which represents the displacement of plane 1 from the control tower, and vector B which represents the displacement of plane 2 from the control tower. Vector A has a magnitude of 220 km and points 32 degrees north of west. This can be sketched as a line of certain length angling upwards from directly west. Vector B is 140 km in magnitude and angles 65 degrees east of north, thus it can be drawn shorter than Vector A and leaning more towards east from north.
Vector D = A - B is the displacement from plane 2 to plane 1. It represents the direction you would need to go if you were at plane 2 and wanted to get directly to plane 1. To find D, rearrange the equation to D = A + (-B). -B is just the B vector in the opposite direction. After making the B vector go in the opposite direction, place it tip to tail with A and the result from tail of A to tip of -B is vector D. Hence, the vectors would be sketched with their tails at the same point and their heads indicating the direction they point towards.

if a can is 12cm high and 8cm wide how much milk can it hold
Final answer:
To find the volume of a cylindrical can, one must apply the formula for volume of a cylinder, V = πr²h, with the given dimensions. The can's volume is approximately 603.19 cubic centimeters or milliliters, translating to about 0.603 liters.
Explanation:
The student is asking about the volume of a can, which is the measure of how much space it occupies or, in this context, how much liquid it can hold. To find the volume of a cylindrical can, we can use the formula V = πr²h, where V is the volume, r is the radius, and h is the height.
Since the can is 12 cm high and 8 cm wide (which is the diameter), the radius would be 4 cm (which is half of the diameter). Substituting these values into the formula gives us V = π(4cm)²(12 cm), which simplifies to V = π × 16 cm² × 12 cm). When calculated, the volume of the can is approximately 603.19 cubic centimeters.
Since the student may also be interested in capacity in terms of common liquid measurements, it is useful to know that 1 cubic centimeter is equivalent to 1 milliliter.
Thus, the can would be able to hold approximately 603.19 milliliters. Given that 1000 milliliters make up 1 liter, the can's capacity would be roughly 0.603 liters, which is a little over half a liter.

To find the area of a circle segment, you need to know the radius and central angle of the segment. Use the formula Area of Circle Segment = ((central angle/360) x πr²) - 0.5r²sin(central angle) to calculate the area.
Explanation:To calculate the area of the segment or shaded area of a circle, you must first need to know the radius of the circle and the central angle of the segment, as these will be necessary for the calculation. The formula for calculating the area of a segment in a circle is Area of Circle Segment = ((central angle/360) x πr²) - 0.5r²sin(central angle).
