The best way to determine how many tangent lines can be created is to actually draw the circle and point itself. Given circle and a point outside, extend lines going from the point to the circle where the line is tangent to the circle. From this, we can get only 2 tangent lines, nothing more. (See attached)

A rectangle has perimeter 84 cm and length 35 cm. What is its width?
Answer: The required width of the rectangle is 7 cm.
Step-by-step explanation: Given that a rectangle has perimeter 84 cm and length 35 cm.
We are to find the width of the rectangle.
Let w represents the width of the rectangle.
According to the given information,
length, l = 35 cm and perimeter, P = 84 cm.
Therefore, we get
[tex]P=2(l+b)\\\\\Rightarrow 84=2(35+w)\\\\\Rightarrow 42=35+w\\\\\Rightarrow w=42-35\\\\\Rightarrow w=7.[/tex]
Thus, the required width of the rectangle is 7 cm.

The Earth's circumference measured at the equator is approximately 1.3148 × 108 feet. What is the number written in standard form?
Answer:
The number written in standard form is [tex]131,480,000[/tex]
Step-by-step explanation:
we have
[tex]1.3148*10^8[/tex]
we know that
[tex]10^8=100,000,000[/tex]
substitute
[tex]1.3148*10^8=1.3148(100,000,000)[/tex]
Remember that
When multiplying decimals by 10, move the decimal point one space to the right
In this case move the decimal point eight spaces to the right
[tex]1.3148(100,000,000)=131,480,000[/tex]
therefore

Consider the following system of equations.
Which statement describes why the system has two solutions?
A. Each graph has one y-intercept, which is a solution.
B. Each graph has one vertex, which is a solution.
C. The graphs of the equations intersect the x-axis at two places.
D. The graphs of the equations intersect each other at two places.
Answer:
D. Each has a slope of –3, but one has a y-intercept of 3 and the other has a y-intercept of –1, which makes the lines equivalent.
Step-by-step explanation:
If you look at the graph (Firstly), you can see that both lines look similar, which is one big hint to this question. But (secondly), like the other person said, both have equivalent y-intercepts in each problem. I saw an open spot for me to answer this so I took it UuU!

If a 40-foot tree casts a 16-foot shadow, find the length of the shadow cast by a 24-foot tree
The shadow of the 24-foot tree will be 9.6 feet.
What is the ratio?
In mathematics, ratios are used to determine the relationship between two numbers it indicates how many times is one number to another number.
Given that:-
If a 40-foot tree casts a 16-foot shadow, find the length of the shadow cast by a 24-foot tree.The shadow of the 24-foot tree will be calculated as follows:-
[tex]\dfrac{40}{16}=\dfrac{24}{x}[/tex]
[tex]x = \dfrac{24\times 16}{40}[/tex]
x = 9.6
Therefore the shadow of the 24-foot tree will be 9.6 feet.

https://brainly.com/question/2328454
#SPJ1
Final answer:
To find the length of the shadow cast by a 24-foot tree, we use the proportion of a 40-foot tree's height to its 16-foot shadow. The resulting shadow length for the 24-foot tree calculated through cross-multiplication is 9.6 feet.
Explanation:
The length of the shadow cast by a 24-foot tree can be found using a simple proportion based on the shadow cast by a 40-foot tree. Since a 40-foot tree casts a 16-foot shadow, the ratio of the height of the tree to the length of its shadow is 40 to 16. This ratio should be the same for the 24-foot tree. To find the shadow length (x) of the 24-foot tree, we set up the proportion as follows:
40 feet (tree height) / 16 feet (shadow length) = 24 feet (tree height) / x feet (shadow length)
Solving for x gives us:
40 / 16 = 24 / x
40 * x = 24 * 16
x = (24 * 16) / 40
x = 384 / 40
x = 9.6 feet
Therefore, the shadow cast by a 24-foot tree would be 9.6 feet long.

What is unit conversion?Multiplication or division by a numerical factor, selection of the correct number of significant figures, and unit conversion are all steps in a multi-step procedure. Unit conversion is the process of changing a quantity's measurement between different units, frequently using multiplicative conversion factors.
Volume is a measurement of three-dimensional space that is occupied. It is frequently expressed mathematically using imperial or SI-derived units.
The correct match is given below:-
2.64 gal ⇒ 10 liters
0.14 cubic meters ⇒ 5 cubic feet
5.35 cubic meters ⇒ 7 cubic yards
6.34 pints ⇒ 3 liters

The only solution of the equation x2 + bx + 16 = 0 is x = 4. What is the value of b?
b = –16
b = –8
b = 8
b = 16
Answer:
Option B is correct.
value of b = -8
Step-by-step explanation:
Given the equation: [tex]x^2+bx+16= 0[/tex]
As per the condition: The only solution for the given equation is, x = 4.
Substitute this value of x =4 in given equation, to solve for b;
[tex](4)^2+b(4)+16= 0[/tex]
Simplify:
[tex]16+4b+16= 0[/tex]
or
[tex]32 + 4b= 0[/tex]
Subtract 32 on both sides, we get;
32 + 4b -32 = 0-32
Simplify:
4b = -32
Divide both sides by 4 we get;
b = -8
therefore, the value of b = -8

What is a quadratic equation?For variable x : ax² + bx + c = 0, where a≠0 is a standard quadratic equation, which is a second-order polynomial equation in a single variable. It has at least one solution since it is a second-order polynomial equation, which is guaranteed by the algebraic basic theorem.
To factor the expression x² - a completely, we need to write it as a product of two binomials.
This can be done using the difference of squares formula, which states that a² - b² = (a + b)(a - b).
If we apply this formula to x² - a, we get:
x² - a = (x + sqrt(a))(x - sqrt(a))
This is a factorization of x² - a into two binomials, where the constant term a is represented by the square root of a.
For the expression x² - a to be completely factored, both factors must be irreducible (meaning they cannot be factored any further). This requires that a be a perfect square.
Out of the given options, 36, 49, and 81 are perfect squares.
