Answer:
TanФ=-1.793
Step-by-step explanation:
[tex]Sin^{2} (A) + Cos^{2} (A) = 1[/tex]
[tex]Sin(A)=\sqrt{1-Cos^{2} (A)}[/tex]
[tex]Tan(A) = \frac{Sin(A)}{Cos(A)}[/tex]
[tex]Tan(A) =\frac{\sqrt{1-Cos^{2}(A) } }{Cos(A)} \\Tan(A) =\frac{\sqrt{1-(-.487)^{2} } }{-.487}=-1.793433202[/tex]

A Census Bureau report on the income of Americans says that with 90% confidence the mean income of all US households in a recent year was $57,005 with a margin of error of $742. This means that
Answer: d. the census bureau got the result 57,005 plus or minus 742 using a method that will capture the true median income 90% of the time when used repeatedly.
Step-by-step explanation:
No t-value has been included in this interval so it cannot be correctly labeled a confidence interval.
This invalidates options a to c.
Option d is therefore the correct answer because it states that the census bureau simply got those results above without claiming that the results constituted a confidence interval.

You have 33 math and science problems for homework. You have 7 more math problems than science problems. How many problems do you have in each subject?
For this question type the two equations that you are using and your solution to the system.
Answer:
x=33/7 m=7+x
Step-by-step explanation:
33 divided by 7 is 5 (when rounded) then you add 5 to 7 and get 12. Hope this helped yu!! Give brainliest.
Answer:
x=33/7 m=7+x
Step-by-step explanation:
so if you divide 33 by 7 you get 4.71428571429 which would be 5 when rounded and then you add 5 to 7 to get 12 I HOPE THIS HELLPEEDD
During an airplanes ascent, the plane reaches a horizontal distance from the airport of 1 km and then 7 km. The plane ascends at a slope of 2/3. Find the vertical distance (y) in feet that the plane traveled during the indicated spots
Answer:
The vertical distance in feet that the plane traveled was 4 Km
Step-by-step explanation:
The Slope of a Line
Suppose we know a line passes across points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
The airplane ascent will be modeled with the equation of a line because we are given a constant slope of m=2/3. We also know the horizontal distances are x1=1 Km and x2=7 Km. Substituting in the formula above:
[tex]\displaystyle \frac{2}{3}=\frac{y_2-y_1}{7-1}[/tex]
Operating:
[tex]\displaystyle \frac{2}{3}=\frac{y_2-y_1}{6}[/tex]
Solving for y2-y1, we get the vertical distance traveled by the plane:
[tex]\displaystyle y_2-y_1=6*\frac{2}{3}=4[/tex]
Thus, the vertical distance in feet that the plane traveled was 4 Km

Suppose that an object is dropped from a height of h meters and hits the ground with a velocity of v meters per second. Then v = 19.6h. If an object is
dropped from a height of 35.9 meters, with what velocity does it hit the ground?
Round your answer to the nearest tenth.
Answer:
The object hits the ground with a velocity of 703.6 m/s.
Step-by-step explanation:
Evaluating Functions
The function that relates the velocity v in meters by second with the height h in meters an object was dropped from is:
v = 19.6h
We are required to evaluate the function above if we know the object was dropped from a height of h=35.9 meters.
Substituting in the equation:
v = 19.6*35.9
v = 703.64 m/s
Rounding to the nearest tenth:
The object hits the ground with a velocity of 703.6 m/s.

Step-by-step explanation:
Substitute the variable!
Basically you just substitute all the x values in.
------------------------------------------------------
x=-5
y=10(-5)+3
y=-50+3
y=-47
If x=-5, then y=-47
------------------------------------------------------
x=-1
y=10(-1)+3
y=-10+3
y=-7
If x=-1, then y=-7
------------------------------------------------------
x=0
y=10(0)+3
y=0+3
y=3
If x=0, then y=3
------------------------------------------------------
x=1
y=10(1)+3
y=10+3
y=13
If x=1, then y=13

Subtract 9 from both sides
-9= -9
8a=3a +10
Subtract -3a from both sides
5a=10
5a=10
5a divided by both sides

We need to convert each city to percentage. Los Angeles is 13/50 and we can double that to convert it to a percentage of 26%. Next is Seattle which is 3/10 and we can multiply that by 10 to get a percentage of 30%. Next is San Francisco, which is at 2/5 and we multiply that by 20 to get a percentage of 40%. Next is Boston which is 43%. The final city is New York City which is 48%. The order of these cities in least to greatest in percentage of public transport use is Los Angeles, Seattle, San Francisco, Boston, and New York City. Therefore the answer is A.
THIS IS MY LAST QUESTION OF MY HOMEWORK PLEASE HELP WITH THESE 2 I'LL GIVE BRAINLIEST
Step-by-step explanation:
Diameter of base of cone = 30 cm .
Hence its radius = 30/2 cm = 15 cm
So , here the figure consists of a hemisphere and a cylinder . Now , here radius of the hemisphere is 15 cm . So , height of the Cylinder = ( 85 - 15 ) cm = 70 cm
→Volume of Cylinder :-
[tex]\large\boxed{\red{ Volume_{cylinder}=\pi r^2 h }}[/tex]
→ Volume = π r²h
→ Volume = 22/7 * ( 15 cm)² * 70 cm
→ Volume = 49,500 cm³ .
Volume of hemisphere :-
[tex]\large\boxed{\green{Volume_{hemisphere}=\dfrac{2}{3}\pi r^3}}[/tex]
→ Volume = ⅔ π r³
→ Volume = ⅔ * 22/7 * (15 cm)³
→ Volume = 10,607.14 cm³ ≈ 10 , 607 cm³ .
Hence Volume = ( 10 , 607 cm³ + 49,500 ) cm³ = 60,107 cm³
