The measures of the angles of a triangle are shown in the figure below. Find the
measure of the smallest angle.
Answers
The smallest measure of the angle in the given triangle is 3x - 15 which is 33°.
What are triangles?A triangle is a polygon with three edges and three vertices. It belongs to the basic geometric shapes. A triangle having vertices A, B, and C is known as triangle ABC. Any three locations in Euclidean geometry that are not collinear result in a distinct triangle and a distinct plane.So, the measure of the smallest angle in the triangle is:
90 + 4x - 7 + 3x - 15 = 1807x + 68 = 1807x = 180 - 68x = 112/7x = 16Now,
4x - 7 = 4(16) - 7 = 57°3x - 15 = 3(16) - 15 = 33°Therefore, the smallest measure of the angle in the given triangle is 3x - 15 which is 33°.

CAF and EFH are congruent because they are corresponding angles of parallel lines cut by transversal.
Explanation:
BC is parallel to DE
Checking the options for angles that are congruent(the same):
1) CAF and EFA
Both angles are not corrsponding angles. They are not equal
2) GAC and DFE are not equal. DFE is a straight line.
3) CAF and EFH are corresponding angles. Hence the angles are congruent.
4) GAB and EFA are not equal. Hence, they are not congruent.
Hence, CAF and EFH are congruent because they are corresponding angles of parallel lines cut by transversal.

If a person travels at a speed of 33 m/s and travels 132 meters, how long does the trip take?
Answers
Answer: 4 seconds.
Step-by-step explanation: Simply divide 132 meters by 33 m/s. This gives you four. (as in the trip took four seconds.)
It is a uniform rectilinear movement which is one in which an object moves in a straight line, in one only direction, with a constant speed.
When we spoke of constant speed we mean that the movement retains the same speed, that is; that the object does not move faster, or slower and always at the same speed.
If a person travels at a speed of 33 m/s and travels 132 meters, how long does the trip take?We obtain the data according to the exercise.
Data:
V = 33 m/s
D = 132 m
t = ?
We have that the uniform motion formula is:
[tex]\large\displaystyle\text{$\begin{gathered}\sf V=\dfrac{d}{t}, \to where \end{gathered}$}[/tex]
[tex]\large\displaystyle\text{$\begin{gathered}\sf V=Speed \end{gathered}$}[/tex][tex]\large\displaystyle\text{$\begin{gathered}\sf D=distance \end{gathered}$}[/tex][tex]\large\displaystyle\text{$\begin{gathered}\sf T=Time \end{gathered}$}[/tex]We solve for time, since that is what we are asked to calculate. And substitute data in the formula.
[tex]\boxed{\large\displaystyle\text{$\begin{gathered}\sf \bf{t=\dfrac{d}{V} } \end{gathered}$}}[/tex]
[tex]\boxed{\large\displaystyle\text{$\begin{gathered}\sf \bf{t=\frac{132 \not{m}}{33 \ \frac{\not{m}}{s} } } \end{gathered}$}}[/tex]

Replacing on the equation:
[tex]\begin{gathered} w(0)=15\ast b^0 \\ w(0)=15\ast1 \\ w(0)=15 \end{gathered}[/tex]The initial number of horses is 15.
Now, if b= 1.35

b = 1.35 = 135%

If b = 1.35, the annual percentage growth rate of the number of horses would be 35%.

6) Raul received a score of 74 on a history test for which the class mean was 70 with a standard deviation of 3. He received a score of 70 on a biology test for which the class mean was 70 with standard deviation 7. On which test did he do better relative to the rest of the class?a)biology testb)history test c)the same
Answers
Solution:
The z score value is expressed as
[tex]\begin{gathered} z=\frac{x-\mu}{\sigma} \\ where \\ x\text{ is the sample score} \\ \mu\text{ is the mean score} \\ \sigma\text{ is the standard deviation of the score} \end{gathered}[/tex]Given that
[tex]\begin{gathered} History: \\ x=74 \\ \mu=70 \\ \sigma=3 \\ Biology: \\ x=70 \\ \mu=70 \\ \sigma=7 \end{gathered}[/tex]To determine which test Raul did better,
step 1: Determine the z score value for the history test.
Thus,
[tex]\begin{gathered} z_{history}=\frac{74-70}{3}=1.333333333 \\ \end{gathered}[/tex]step 2: Determine the z score value for the biology test.
[tex]z_{biology}=\frac{70-70}{7}=0[/tex]step 3: Determine the probability that he did better in the history test.
Thus, from the normal distribution table,
[tex]Pr(history)=0.9088[/tex]step 4: Determine the probability that he did better in the biology test.
From the normal distribution table,
[tex]Pr(biology)=0.5[/tex]Since the probability that he did better in history is higher than the probability he did better in the biology test, this implies that he did better in the history test, relative to the rest of the class.

2.) for the line represented by the given equation, find both the X intercept and the y-intercept. (Don’t simply look on the graphing calculator ). Make sure you indicate which answer is the x-intercept and which is the y-intercept . Then graph the line
Answers
Answer:
To find the y-intercept, we substitute x=0 in the given equation:
[tex]\begin{gathered} y=\frac{1}{2}\cdot0+3, \\ y=3. \end{gathered}[/tex]Therefore, the y-intercept has coordinates (0,3).
To find the x-intercept, we set y=0, and solve for x:
[tex]\begin{gathered} 0=\frac{1}{2}x+3, \\ 0-3=\frac{1}{2}x+3-3, \\ -3=\frac{1}{2}x, \\ 2\cdot(-3)=2\cdot(\frac{1}{2}x), \\ x=-6. \end{gathered}[/tex]Therefore, the x-intercept has coordinates (-6,0).

A geometric sequence has allpositive terms. The sum of thefirst two terms is 15 and the sumto infinity is 27.a Find the value of the commonratio.b Hence, find the first term.
Answers
a) Common ratio = 2/7
b) First term = 135/7
Explanations:The formula for finding the sum of a geometric progression is expressed as:
[tex]S_n=\frac{a(r^n-1)}{r-1}[/tex]Since the sum of the first two terms is 15, then
S2 = 15
n = 2
Substitute into the formula:
[tex]\begin{gathered} S_2=\frac{a\mleft(r^2-1\mright)}{r^{}-1} \\ 15=\frac{a(r+1)\cancel{r-1}}{\cancel{r-1}} \\ 15=a(r+1) \end{gathered}[/tex]Also, the sum to infinity of a geometric sequence is expressed as:
[tex]\begin{gathered} S_{\infty}=\frac{a}{1-r} \\ _{} \end{gathered}[/tex]Substitute the given values into the formula:
[tex]27=\frac{a}{1-r}[/tex]Solve both expressions simultaneously
[tex]\begin{gathered} 15=a(r+1) \\ 27=\frac{a}{1-r} \end{gathered}[/tex]
Divide both expressions to have:
[tex]\frac{15}{27}=\frac{1-r}{r+1}[/tex]Cross multiply and solve for the common ratio "r"
[tex]\begin{gathered} 15(r+1)=27(1-r) \\ 15r+15=27-27r \\ 15r+27r=27-15 \\ 42r=12 \\ r=\frac{12}{42} \\ r=\frac{2}{7} \end{gathered}[/tex]Hence the value of the common ratio is 2/7
b) Get the first term of the sequence;
Using the formula:
[tex]\begin{gathered} 27=\frac{a}{1-r} \\ 27=\frac{a}{1-\frac{2}{7}} \\ 27=\frac{a}{(\frac{5}{7})} \\ a=27\times\frac{5}{7} \\ a=\frac{135}{7} \\ \end{gathered}[/tex]Hence the first term of the sequence is 135/7

Answers
ANSWER:
We have the following:
1. A given chord in a circle is perpendicular to a radius through its center and is a distance less than the radius of the circle.
2. A circle with center C has a radius of 5 units. If a 6-unit chord AB is drawn at a distance D from the center of the circle, determine the value of D.
3.
Given:
Radius = 5 units
Length of chord = 6 units
A radius that meets the chord at center O divides it into two equal parts. Therefore:
AO = OB = 3 units
We can apply the Pythagorean theorem on the resulting triangle COB to determine the distance D, like this:
[tex]\begin{gathered} h^2=a^2+b^2 \\ \\ h=CB=R=5 \\ \\ a=OC=D \\ \\ b=OB=3 \\ \\ \text{ We replacing:} \\ \\ 5^2=D^2+3^2 \\ \\ 25=D^2+9 \\ \\ D^2=25-9 \\ \\ D=\sqrt{16} \\ \\ D=4 \end{gathered}[/tex]Therefore, the chord is at a distance of 4 units to the center of the circle.
