which of the following is the same as cos15°
Answer:
cos15 is equivalent to sin(75)
Step-by-step explanation:
solving for cos15 degrees gives you ((√(3)+1)*√(2))/4 which is the same as the sin(75)

Match the picture to the reason that would prove the triangles congruent.
Options:
NONE
ASA
SSS
SAS
AAS
HL
Answer:
Answer: SAS
Step-by-step explanation:
We must prove that triangles ABC and EDC are congruent.
Since BD bisects AE, then AC is congruent with CE.
Since AE bisects BD, then BC is congruent with CD
Angle C is 90° in the triangle EDC and is also 90° in triangle BCA because they are vertical angles.
Being two sides and the included angle congruent, then both triangles are similar by the SAS theorem.

While exploring a volcano, Zane heard some rumbling, so he decided to climb up out of there as quickly as he
could.
Zane's elevation relative to the edge of the inside of the volcano (in meters) as a function of time (in seconds) is
graphed.
how high did zane climb every 7 seconds
A 7/5 meters
B 5 meters
C 5/7 meters
D 7 meters
Answer:
Step-by-step explanation:
Zanes can climb 5/7 meters for every 7 seconds.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
This is clearly shown in the graph of Zane's elevation relative to the rim of the volcano in meters as a function of time in seconds.
The graph showed that Zane was climbing the volcano at a constant rate, creating a linear graph of his movement.
From the graphical representation, it could be seen from the graph that the x-intercept is (0,5) and the y-intercept is (7,0)
Slope of line is m=5/7
Hence, Zanes can climb 5/7 meters for every 7 seconds.

distance between a(3,9) b(-10,4)
Answer:
√194 i think
Step-by-step explanation:
Answer:
[tex]\boxed {d = \sqrt{194}}[/tex]
Step-by-step explanation:
Use the Distance Formula to help you find the distance between the two given points:
[tex]d = \sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}}[/tex]
First point: [tex](x_{1}, y_{1})[/tex]
Second point: [tex](x_{2}, y_{2})[/tex]
-Substitute the two given points onto the formula:
First point: [tex](3, 9)[/tex]
Second point: [tex](-10, 4)[/tex]
[tex]d = \sqrt{(-10 - 3)^{2} + (4 - 9)^{2}}[/tex]
-Then, you solve for the distance:
[tex]d = \sqrt{(-10 - 3)^{2} + (4 - 9)^{2}}[/tex]
[tex]d = \sqrt{(-13)^{2} + (-5)^{2}}[/tex]
[tex]d = \sqrt{169 + 25}[/tex]
[tex]\boxed {d = \sqrt{194}}[/tex] (since the number cannot be square rooted, the number will stay the same)
Therefore, the distance is [tex]\sqrt{194}[/tex].

write the linear equation from the given information in slope intercept form passing through (-2,8) and perpendicular to y=2x+5
Answer:
y = [tex]-\frac{1}{2}[/tex] x + 9
Step-by-step explanation:
Given parameters:
Coordinates = (-2,8)
Equation of the line y = 2x + 5;
Unknown:
Linear equation of a line perpendicular = ?
Solution:
From the given expression, a line perpendicular will have a negative inverse of the slope given.
y = 2x + 5
Equation of a line is y = mx + c;
y and x are the coordinates
m is the slope
c is the intercepts
y = 2x + 5 ;
The slope is 2;
A line perpendicular will have a slope of [tex]-\frac{1}{2}[/tex]
Since y = 8 and x = -2, let us find c;
8 = 2 x [tex]-\frac{1}{2}[/tex] + c
8 = -1 + c
c = 8+1 = 9
The equation of the line is;
y = [tex]-\frac{1}{2}[/tex] x + 9

Here, P = $3000, N = 1.5 years, R = 10%
[tex]SI = \frac{PNR}{100} \\ \\ SI = \frac{3000 \times 1.5 \times 10}{100} \\ \\ SI = 450 \\ \\ [/tex]

Donna drove 200 miles and was reimbursed $1,620. Part A: Create an equation that will determine the number of days on the trip. (3 points) Part B: Solve this equation justifying each step with an algebraic property of equality. (6 points) Part C: How many days did Donna spend on this trip? (1 point)
Answer:
See below
Step-by-step explanation:
Part ALet number of days be d, then the equation is:
50d + 200*0.6 = 1620Part BSolution of the equation
50d + 120 = 162050d + 120 - 120 = 1620 - 120 ⇒ subtraction property of equality50d = 150050d / 50 = 1500/50 ⇒ division property of equalityd = 30Part C30 days as aboveBruce drew a scale drawing of a house and its lot. The house's driveway, which is 17 feet
wide in real life, is 34 inches wide in the drawing. What scale did Bruce use for the drawing?
Answer:
1/6
Step-by-step explanation:
Convert 17 feet to inches. 17×12 = 204
204 inches to 34 inches.
204/34 = 6
Remember we are scaling down
204× 1/6 = 34
