What is the question?

Answer:

yes, it is a right triangle.

Step-by-step explanation:

you could use the pythagorean theory to check:

[tex]a^{2} + b^{2} = c^{2}[/tex]

(the hypotenuse is the longest side)

[tex]17.5^{2} + 6^{2} = 18.5^{2}[/tex]

Answer:

7) 65°8) 25°

Step-by-step explanation:

Question 7

Angle formed by 2 chords is half of the sum of the intercepted arcs

x = 1/2(72° + 58°) = 1/2(130°) = 65°

Question 8

Angle formed by 2 secants is half of the difference of the intercepted arcs

x = 1/2(360° - (130° + 98° + 41°) - 41°) = 1/2(50°) = 25°

A business traveler was wondering how the taxi meters in a particular city work. She kept track of the distance traveled on each of her taxi rides and the amount
she paid for each of her fares. She then plotted the data points and found that while they didn't exactly form a line (probably due to varying times spent stuck in
traffic), they could be approximated by the line y = 1.75x+2.25, where x is the distance traveled in miles and y is the fare in dollars. According to the model, about
how much will a 3 mile ride cost?
A. $5.25

B. $6.75

С. $7.50

D. $8.50

Answers

C because you plug 3 in for x and the equation becomes 1.75(3)+2.25=5.25+2.25=7.50

Anne bought a pair of jeans that originally cost $33, but are currently marked down 25%. What will is the new price of the jeans after the markdown? Pls I need to show work

Answers

Answer:

The jeans are now $24.75.

Step-by-step explanation:

Two ways to do this. Either you multiply 33 by 0.25 and get 8.25 which is 25% percent of the price and then you just subtract $8.25 from $33 and end up with $24.75, OR you can multiple 33 by 0.75 and you end up with $24.75.

The answer would be 16 feet
As a square has 4 sides that are equal to one another.
So all sides equal 4 feet each
Perimeter is the outside border so add 4+4+4+4=16 feet
I hope this helps!
Since a square has 4 sides, and each side is 4 feet, if you just multiply the amount of sides the square has by the distance being 4 feet, you get 16 feet which is your answer.

m=-6/(6+6)

m=-6/12

m=-1/2

y-y1=m(x-x1)

y-5=-1/2(x-(-6))

The sum of 3 consecutive even numbers is 78.

Answers

Answer:

25, 26, 27

Step-by-step explanation:

set up an equation so 3 consecutive numbers are n, n+1, and n+2

So n + n +1 + n + 2 = 78, so 3n + 3 = 78, 3n = 75, so n = 25

so the numbers are 25, 26, 27

A ball is thrown into the air with an initial upward velocity of 48 ft/s. It height h in feet after t seconds is given by the function h (t)=-16t^2+48t+4.

In how many seconds will the ball reach its maximum height?

Answers

Answer:

Step-by-step explanation:

h(t)=-16t^2+48t+4

dh/dt=-32t+48

d2h/dt2=-32

Since acceleration is always negative when the velocity, dh/dt=0, it will occur at the maximum height.

dh/dt=0 when

-32t+48=0

-32t=-48

t=1.5 seconds

Without calculus, the vertex of a parabola will be at -b/(2a) of the quadratic equation. In this case

-48/(2(-16))

-48/-32

These slaves constituted a peculiar and powerful interest. All knew that this interest was, somehow, the cause of the war. To strengthen, perpetuate, and extend this interest was the object for which the insurgents would rend the Union, even by war; while the government claimed no right to do more than to restrict the territorial enlargement of it. Neither party expected for the war, the magnitude, or the duration, which it has already attained. Neither anticipated that the cause of the conflict might cease with, or even before, the conflict itself should cease. Each looked for an easier triumph, and a result less fundamental and astounding. Both read the same Bible, and pray to the same God; and each invokes His aid against the other. It may seem strange that any men should dare to ask a just God's assistance in wringing their bread from the sweat of other men's faces; but let us judge not that we be not judged. The prayers of both could not be answered; that of neither has been answered fully. The Almighty has His own purposes. "Woe unto the world because of offenses! for it must needs be that offenses come; but woe to that man by whom the offense cometh! If we shall suppose that American slavery is one of those offenses which, in the providence of God, must needs come, but which, having continued through His appointed time, He now wills to remove, and that He gives to both North and South, this terrible war, as the woe due to those by whom the offense came, shall we discern therein any departure from those divine attributes which the believers in a Living God always ascribe to Him? Fondly do we hope. fervently do we pray that this mighty scourge of war may speedily pass away. Yet, if God wills that it continue, until all the wealth piled by the bondman's two hundred and fifty years of unrequited toil shall be sunk, and until every drop of blood drawn with the lash, shall be paid by another drawn with the sword, as was said three thousand years ago, so still it must be said "the judgments of the Lord are true and righteous altogether." With malice toward none; with charity for all; with firmness in the right, as God gives us to see the right, let us strive on to finish the work we are in; to bind up the nation's wounds; to care for him who shall have borne the battle, and for his widow, and his orphan-to do all which may achieve and cherish a just, and a lasting peace, among ourselves, and with all nations. 1.
