In an isosceles triangle with one angle measuring 102°, the other two angles are both 39°. The sum of all angles in a triangle is 180°. Therefore, the largest angle is 102° and the smallest are both 39°.
If a triangle is isosceles and one angle measures 102°, we can determine the measures of the other two angles. Since it's an isosceles triangle, two angles are the same. According to the properties of triangles, we know that the sum of all three angles must be 180°. Therefore, we can subtract the known angle from 180° to determine the sum of the remaining two angles.
180° - 102° = 78°
Since the two remaining angles are equal, we divide 78° by 2 to find the measure of each angle.
78° ÷ 2 = 39° each
The measures of the largest and smallest angles in the isosceles triangle are 102° (the largest) and 39° (the smallest).

Tracy pays $8.50 of her monthly life insurance premium and her employer covers the rest of her monthly premium is $32.25 what is the annual value to Tracey of this benefit
Final answer:
Tracy's employer pays $23.75 each month towards her life insurance premium. The annual value of this benefit to Tracy is $285, calculated by multiplying the monthly employer contribution by 12.
Explanation:
The question is asking to calculate the annual value of the benefit that Tracy receives from her employer for her life insurance. Tracy pays $8.50 monthly and her employer covers the remainder, making the total monthly premium $32.25. To find the annual value of the benefit, we need to first determine how much her employer pays each month and then multiply this by 12 to get the annual value.
First, we subtract Tracy's contribution from the total premium:
$32.25 - $8.50 = $23.75
This is the monthly contribution by the employer. Now, to find the annual value, we multiply the monthly employer contribution by 12:
$23.75 × 12 = $285. Therefore, the annual value of the benefit that Tracy receives is $285.

In a system of linear equations, the slope of one line is the negative reciprocal of the slope of the other line. Is this system independent, dependent, or inconsistent?
Final answer:
An independent system of linear equations has two lines that intersect at exactly one point. If the slope of one line is the negative reciprocal of the other, the lines are perpendicular, indicating they intersect once and the system is independent.
Explanation:
If the slope of one line in a system of linear equations is the negative reciprocal of the slope of the other line, this indicates that the two lines are perpendicular to each other. Perpendicular lines intersect at one point and therefore, the system of equations is independent. An independent system has a single unique solution, meaning that there is exactly one point where the two lines cross.
In terms of graphs and equations, the slope or 'm' in the equation y = mx + b represents the rate at which the dependent variable changes with respect to the independent variable. The negative reciprocal relationship between slopes of two lines means that one will rise (positive slope) and fall (negative slope) at the same rate but in opposite directions, ensuring they intersect just once unless the y-intercepts (b) are also identical, which would make them the same line (dependent system) rather than intersecting lines.
WHAT IS 6.4 DIVIDED BY 43.52

Kathryn draws three pairs of intersecting lines. In each figure, she measures a pair of angles. What is a reasonable conjecture for Kathryn to make by recognizing a pattern and using inductive reasoning? When a pair of lines intersect, the vertical angles are acute. When a pair of lines intersect, all of the angles formed are right angles. When a pair of lines intersect, the vertical angles are congruent. When a pair of lines intersect, all of the angles formed are congruent.
The reasonable conjecture for Kathryn to make by recognizing a pattern and using inductive reasoning is:
When a pair of lines intersect, the vertical angles are congruent.
Step-by-step explanation:The vertical angles are the opposite angles that are formed by the intersection of two lines. They are also known as Vertically opposite angles.
We know that when a pair of lines intersect then the vertical angles are always congruent.
However the measure of the angles may be acute or obtuse or right angle.

What is the coefficient of the fourth term in the expansion of (x + 3)4?
Final answer:
The coefficient of the fourth term in the expansion of (x + 3)⁴ is calculated using the binomial theorem, which results in a coefficient of 108.
Explanation:
To find the coefficient of the fourth term in the expansion of (x + 3)⁴, we can use the binomial theorem. The binomial theorem states that when a binomial is raised to a power, the expansion consists of terms in the form of [tex]C(n, k) \times a^{n-k} \times b^k[/tex], where C(n, k) is the binomial coefficient. In our case a = x and b = 3, and n = 4.
For the fourth term where k = 3, the term would be [tex]C(4, 3) \times x^{4-3} \times 3^3[/tex]. The binomial coefficient C(4, 3) is equal to 4 because there are four ways to choose three items out of four. Therefore, the coefficient is 4 × 3³ = 4 × 27 = 108. So, the coefficient of the fourth term in the expansion of (x + 3)⁴ is 108.

108 cm
Given the function f(x)= x^4+6x^3-x^2-30x+4
Use the intermediate value Theorem to decide which of the following intervals contains at least one zero (there are 4 answers)
A) [-5,-4]
B) [-4,-3]
C) [-3,-2]
D) [-1,0]
E) [0,1]
F) [1,2]
The correct answers are a,b,e,f
By applying the Intermediate Value Theorem to the function f(x)=x^4+6x^3-x^2-30x+4, we find that the intervals containing at least one zero, or root, are [-4,-3], [-3,-2], [-1,0], and [0,1].
Explanation:In mathematics, particularly in calculus, the Intermediate Value Theorem (IVT) is used to show that a given interval has at least one zero, or root, of a function. In this case, the function is f(x)=x^4+6x^3-x^2-30x+4.
To apply IVT, we calculate the function value at the endpoints of the intervals. If the function values at the endpoints of an interval have different signs, then by IVT, there is at least one zero in that interval.
f(-5)=625+750-25+150+4=1504f(-4)=256+384-16+120+4=748f(-3)=81+162-9+90+4=328f(-2)=16+48-4+60+4=124f(-1)=1+6-1+30+4=40f(0)=4f(1)=1+6-1-30+4=-20f(2)=16+48-4-60+4=4A change in sign between the function values at the endpoints of an interval indicates there is at least one root in that interval. Thus, by checking the signs of the consecutive function values, we can conclude that the intervals which contain at least one root are [-4,-3], [-3,-2], [-1,0], and [0,1].

A photo 5 inches wide and 8 inches long is enlarged. How long is the new photo if it is (1)10 inches; (2)15 inches; (3)8 inches wide?
Answer:
1.16 in
2.24 in
3.12.8 in
Step-by-step explanation:
We are given that
Width of photo=5 in
Length of photo=8 in
We have to find the length of new photo in each case.
1. Let x represent the width and y represents the length of photo.
When width increase then length of photo is also increases then it is direct proportion.
[tex]\frac{x_1}{y_1}=\frac{x_2}{y_2}[/tex]
Substitute the values then we get
[tex]\frac{5}{8}=\frac{10}{y}[/tex]
[tex]y=\frac{10\times 8}{5}=16[/tex]
Hence, the length of photo=16 in
2.Width=x=15 in
Again using the formula
[tex]\frac{5}{8}=\frac{15}{y}[/tex]
[tex]y=\frac{15\times 8}{5}=24[/tex]
Hence, the length of new photo=24 in
3. Width =x=8 in
Substitute the values in the given formula
[tex]\frac{5}{8}=\frac{8}{y}[/tex]
[tex]y=\frac{8\times 8}{5}=\frac{64}{5}=12.8[/tex]
Hence, the length of new photo=12.8 in

What are arithmetic and geometric sequence?An arithmetic sequence is a set of numbers in which every no. next to the previous number has the same common difference
d = aₙ - aₙ₋₁ = aₙ₋₁ - aₙ ₋₂.
In a geometric sequence numbers are written in the same constant ratio(r).
It means every next number is a multiple of a common constant and the previous number.
r = aₙ/aₙ₋₁ = aₙ-₁/aₙ₋₂.
Given, Joey saved $2 today. If he doubles the number of dollars he saves each day.
This can be formed as a geometric sequence with common ratios(r) = 2.
