Answer:
yesnoStep-by-step explanation:
For three side lengths to form a triangle, the sum of the shorter two must exceed the longest.
__
1)7 + 11 = 18 > 14 . . . . Will make a triangle.
__
2)2 + 8 = 10 . . . not greater than 10. Will not make a triangle.
__
This is a direct consequence of the triangle inequality, which requires for sides a, b, c that ...
a +b > c and b +c > a and c +a > b
_____
Additional comment
There is a version of the triangle inequality that uses the ≥ comparison, rather than >. If that is the version of the inequality you are using, then both these sets of lengths will form a triangle. The second "triangle" will look like a line segment and have zero area.

Answer:
x=2
Step-by-step explanation:
We must equate f(x)=g(x) ;
x+3=2x^2-3
2x^2-x-6=0, when we solve for x in this equation we get 2 solutions:
x=2, x=-1.5
Since -1.5 is not seen in the table, we consider the value 2.
At x=2 in the table both f(x) and g(x) have the same value 5 and proves f(x)=g(x) has a solution at x=2.
Answer:
x = 2
Step-by-step explanation:
Given:
f(x) = |x| + 3
g(x) = 2x² - 3
From inspection of the table, the equation f(x) = g(x) has a solution when
x = 2 as this is the only value of x when the two functions have the same value of 5.
See attached graph for proof. The points of intersection are the solutions: (-2, 5) and (2, 5). (Since x = -2 is not in the given table, this is not included in the answer to this question).

The Hormel Corporation has an annual dividend rate of $1.04. If you owned 5,000 shares of
Hormel, how much would you receive annually in dividends?
$4,900
$5,000
$5,100
$5,200
Answer:
$4,900
Step-by-step explanation:
[tex]\frac{\mbox{number of shares}}{\mbox{annual dividend}} = \frac{5,000}{1.04}[/tex]
This simplifies to 4807.7, which you can round to $4,900.

Answer: 21
Step-by-step explanation:
The measure of the tangent to the circle CD = 21
What is a Circle?A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle
The perimeter of circle = 2πr
The area of the circle = πr²
where r is the radius of the circle
The standard form of a circle is
( x - h )² + ( y - k )² = r²,
where r is the radius of the circle and (h,k) is the center of the circle
Given data ,
Let the 2 tangents to the circle be AE and BD respectively
The measure of the line segment BD = 56
Now , the ratio of the line AE is
AC : AE = 5 : 3
The measure of AE = measure of CD
Let the value of AC = 5x
Let the value of AE = 3x
Now , the measure of AE = measure of BD
Substituting the values in the equation , we get
5x + 3x = 56 be equation (1)
On simplifying the equation , we get
8x = 56
Divide by 8 on both sides of the equation , we get
x = 7
Now , the measure of CD = 3x
Substituting the value of x in the equation , we get
CD = 3 ( 7 ) = 21
Therefore , the measure of CD = 21
Hence , the measure of CD = 21

Answer:
58.5; 300; 196.5
Step-by-step explanation:
Area of triangle 1 = (1/2) * 9 * 13 = 58.5 inches^2
Area of whole figure = (1/2) * (14+26) * 15 = 300 inches ^2
Area of shaded region = 300 - 58.5 - [(1/2) * 6 * 15] = 241.5 - 45 = 196.5 inches^2

b. Write another expression in simplest form that shows the difference between the perimeter of the larger triangle and the perimeter of the smaller triangle.
c. Find the perimeter for each triangle when x = 3
Answer:
Step-by-step explanation:

Answer:
The side b is 2√6 unit
Step-by-step explanation:
in right triangle ΔABC,∠C=900,a=5,c=7;c is
the side opposite to the right angle, so it is hypotenuse,
aandb are the adjacent sides of the right angle .
We know in right triangle ΔABC,a²+b²=c²
∴5²+b²=7²or
b²=49−25=24
∴√b²=√24
b=√24
b=2√6
. The side b is 2√6 unit [Ans]
AB = 7 cm
CB = 5 cm
AC = 2√6cm
According to Pythagoras Theorem,
AC²=BC²+AB²
(2√6)²=5²+7²
24=25+49
24=74
Hence, it is not a right-angled triangle ABC.

Answer:
[tex]y = \frac{5}{4} x + 25[/tex]
Step-by-step explanation:
We were told that the equation of the line we are looking for is perpendicular to
[tex]y = - \frac{4}{5} x + 5[/tex]
We know that the gradient of perpendicular lines when multiplied is equal to -1, therefore
[tex] line \: .1 \times \: line \: .2 = - 1 \\ \\ \frac{4}{5} \times line \: .2 = - 1 \\ \\ line \: .2 = \frac{ - 1}{ \frac{4}{5} } [/tex]
[tex]line\: .2 = \frac{5}{4} \: \: \: \: y = 15 \: \: \: \: x = - 8 \\ \\ y = mx + c \\ \\15 = ( \frac{5}{4} ) - 8 + c \\ \\ 15 = - 10 + c \\ 15 + 10 = c[/tex]
[tex]25 = c \\ \\ therefore \: the \: equation \: of \: the \: line \: is \: \\ \\ y = \frac{5}{4} x + 25[/tex]
Idil wants to ride her bicycle 41.4 miles this week. She has already ridden 15 miles. If she rides for 4 more days, what is the average number of miles she would have to ride each day to meet her goal?
Answer:
6.6
Step-by-step explanation:
41.4-15 = 26.4
26.4 divided by 4 equals 6.6
Idil would need to ride an average of 6.6 miles per day for the next 4 days to meet her goal of 41.4 miles for the week.
How find the average number of miles she would have to ride each day to meet her goal?To find the average number of miles Idil would have to ride each day to meet her goal, we can use the following formula:
Average miles per day = (Total miles - Miles already ridden) / Number of days remaining
Given information:
Total miles she wants to ride = 41.4 miles
Miles already ridden = 15 miles
Number of days remaining = 4 days
Now, let's calculate the average miles per day:
Average miles per day = (41.4 - 15) / 4
Average miles per day = 26.4 / 4
Average miles per day = 6.6
So, Idil would need to ride an average of 6.6 miles per day for the next 4 days to meet her goal of 41.4 miles for the week.
