What is a vector?The quantity which has magnitude, and direction and follows the law of vector addition is called a vector.
George Washington tosses a baseball with an underlying speed of 20.2 feet each second at a point of 69° degrees with the even.
The initial vertical velocity of the ball is given as,
⇒ 20.2 x sin 69°
⇒ 20.2 x 0.9335
⇒ 18.9 feet per second
The initial horizontal velocity of the ball is given as,
⇒ 20.2 x cos 69°
⇒ 20.2 x 0.3583
⇒ 7.2 feet per second
The initial vertical and horizontal velocity of the ball will be 18.9 feet per second and 7.2 feet per second, respectively. Then the correct option is C.

A pounds of apples and b pounds of plums were packed into n boxes. How many pounds of fruit are there in each box?
Answer:
(a + b) / n
Step-by-step explanation:
Pounds of apple in box = a
Pounds of plum in box = b
Number of boxes used in packing = n
The amount fruit in pounds that are in each box :
Total pound of fruits / number of boxes used
Total pounds of fruit = a + b
Number of boxes used = n
Hence, we have ;
(a + b) / n

What is an expression?An expression, often known as a mathematical expression, is a finite collection of symbols that are well-formed in accordance with context-dependent principles. Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.Many authors make a distinction between an expression and a formula, with the former designating a mathematical object and the latter a claim about such objects.Solution -The piece of rope is 1m long.
Carter divided the ropes into three equal parts by tying up the knot.
1 meter = 3 foot.
Therefore, divide 3 by 3.
[tex]\frac{3}{3} =1[/tex] foot.
Therefore, each section is 1 foot long.

Emila bought 3 2/3 kilogram of sugar on wednesday she bought 3/10 kilograms of sugar less on Thursday. How uch sugar did she buy on Thursday?
Answer:
[tex]1\frac{7}{10}[/tex] kg of sugar
Step-by-step explanation:
Amount of sugar on Wednesday: [tex]3\frac{2}{3}[/tex] kg
Convert the mixed number fraction to an improper fraction (multiply the whole number by the numerator)
[tex]3\frac{2}{3}[/tex] ⇒ [tex]\frac{6}{3}[/tex] ⇒ [tex]2[/tex]
Therefore, Emila bought 2 kg of sugar on Wednesday.
Because Emila bought [tex]\frac{3}{10}[/tex] kg less sugar on Thursday, subtract [tex]\frac{3}{10}[/tex] from [tex]2[/tex].
[tex]2-\frac{3}{10}[/tex]
Convert 2 into a fraction with 10 as the denominator
[tex]=\frac{20}{10} -\frac{3}{10}\\=\frac{17}{10}[/tex]
Convert the fraction into a mixed number
[tex]= 1\frac{7}{10}[/tex]
Therefore, Emila bought [tex]1\frac{7}{10}[/tex] kg of sugar on Thursday.

Which value, to the nearest tenth, is the smallest solution of f(x) = g(x) if f(x) = ln(x + 5) – 1 and g(x) = x3 – 2x + 1?
Answer:
There are two possibilities of determine which solution is the smallest one:
(i) The smallest solution is the value of [tex]x[/tex] has the smallest distance with respect to origin: [tex](x_{2},y_{2}) = (0.18,0)[/tex]
(ii) The smallest solution is the most negative value: [tex](x_{1},y_{1}) = (-1.577,0)[/tex]
Step-by-step explanation:
Let [tex]f(x) = g(x)[/tex], [tex]f(x) = \ln (x+5)-1[/tex] and [tex]g(x) = x^{3}-2\cdot x + 1[/tex], then we have the following implicit equation:
[tex]\ln (x+5)-x^{3}+2\cdot x -2 = 0[/tex] (1)
This equation cannot be solved by analytical means. There are two different strategies to solve this expression: (i) Numerical methods, (ii) Graphical methods. We decide to use the second method:
Let suppose that we use this function [tex]h(x) = \ln (x+5) -x^{3}+2\cdot x - 2[/tex]. By the help of a graphing tool, we find the smallest solution such that [tex]h(x) = 0[/tex]. There are three possible solutions: [tex](x_{1},y_{1}) = (-1.577,0)[/tex], [tex](x_{2},y_{2}) = (0.18,0)[/tex], [tex](x_{3}, y_{3}) = (1.376, 0)[/tex]
There are two possibilities of determine which solution is the smallest one:
(i) The smallest solution is the value of [tex]x[/tex] has the smallest distance with respect to origin: [tex](x_{2},y_{2}) = (0.18,0)[/tex]
(ii) The smallest solution is the most negative value: [tex](x_{1},y_{1}) = (-1.577,0)[/tex]
The smallest smallest solution of f(x) = g(x) will be [tex]\rm \left(-1.577,0.223\right)[/tex]
What exactly is a function?A function is a statement, rule, or law that specifies the connection between two variables. Functions are common in mathematics and are required for the formulation of physical connections.
Given functions;
f(x) = ln(x + 5) – 1
g(x) = x³ – 2x + 1
After graphing both the function, we get the three solutions of the given equation,
[tex]\rm \left(-1.577,0.223\right)[/tex]
[tex]\left(0.18,0.645\right)[/tex]
[tex]\left(1.376,0.853\right)[/tex]
Hence,the smallest smallest solution of f(x) = g(x) will be [tex]\rm \left(-1.577,0.223\right)[/tex]

Answer:
The y intercept is added to the new parent function.
Step-by-step explanation:
The parent function changed because the y intercept (SLOPE) was added into the new parent function. In order to prove that the change took place with the y intercept being added to the function, you can use any value from 2 and up.
Completion of substitution for X:
Original parent function: Plug in 2 for x
(2)^3 = 8
Completion of substitution for X with NEW parent function: plug in 2 for x
(2)^3 + 2 = 10

= x² + 7x + x + 7
= x (x + 7) + 1 (x + 7)
= (x + 1) (x + 7)
Option D is the answer.
7. x² - x - 72
= x² - 9x + 8x - 72
= x(x - 9) + 8(x - 9)
Option B is the answer.

= (x - 7) (x + 7) [formula used a² - b² = (a-b)]
Option D is the answer.
9. 9x² - 54x + 72
= 9(x² - 6x + 8)
= 9(x² - 4x - 2x + 8)

1A) Quad ABCD is inscribed in the circle. Find x. *
1B) Using your answer from above, what is angle A? *
Step-by-step explanation:
2x + 9° + 3x + 1° =180° (opposite angles of a cyclic quadrilateral are supplementary)
5x + 10° = 180°
5x = 180° - 10°
5x = 170°
x = 34°
Now
Angle A

A windshield wiper is 50 cm long. In one sweep it turns through an angle of 115°. Calculate the distance (length) it covers in one sweep. Round to the nearest whole number.
Answer:
The distance in one sweep is 100 cm approximately
Step-by-step explanation:
Here, we want to calculate the distance the wiper covers in one sweep
Mathematically;
we have a structure like an arc of a circle. It is the length of this arc we want to calculate.
The formula for the length of an arc is;
theta/360 * 2 * pi * r
r is the radius which in this case is 50 cm
We have ;
115/360 * 2 * 3.1412 * 50 = 100 cm approximately
