Answer:

Part (One): A) The triangles are congruent/

Part (Two): D) the slop of the line is not equal to a/b or c/d

Step-by-step explanation:

1. The triangles cannot be congruent since there is only one 90 degree angle. for each of them.

2. The slope for every point would always be the same. The only possible answer to be that the slope of the line isn't equal to a/b nor c/d. It wouldn't make sense if the slope of the line was equal to a/b or c/d was true and if the slope of the line was equal to a/b or c/d at the same time.

Answer:

Part 1 - the triangles are congruent.

Part 2 - the slope of the line is not equal to a/b or c/d.

Step-by-step explanation:

Congruent - same size

- same length

- same angles

*IT IS A FALSE

Slope - equal to a/b or c/d

- formula is y/x

*IT IS A FALSE

(Correct me if i am wrong)

Answer:

The Washington High School won the meet by scoring 162 points

The Johnson High School came in second place by scoring 159 points, 3 points less than the winner.

Step-by-step explanation:

Arithmetics

We need to perform a number of basic arithmetics operations and derive conclusions out of the results.

We know that

10 points are awarded for each first-place finish
8 points are awarded for each second-place finish
7 points are awarded for each third-place finish

* Washington High School had 10 first-place finishes, 6 second-place finishes, and 2 third-place finishes.

Total points: 10*10+6*8+2*7=162 total points

* Johnson High School had 8 first-place finishes, 9 second-place finishes, and 1 third-place finish.

Total points: 8*10+9*8+1*7=159 total points

* Roosevelt High School had 4 first-place finishes, 5 second-place finishes, and 4 third-place finishes.

Total points: 4*10+5*8+4*7=108 total points

* Lewis High School had 3 first-place finishes, 3 second-place finishes, and 6 third-place finishes.

Total points: 3*10+3*8+6*7=96 total points

The Washington High School won the meet by scoring 162 points

The Johnson High School came in second place by scoring 159 points, 3 points less than the winner.

Eddie bought 27 2/5 inches of wire for a home improvement project. How many 12 inches sections can he make from it?

goblinko [34]

Simply divide your wire by 12 and cut off the excess (as it cannot make a full 12-inch section).

27 $\frac{2}{5}$ ÷12=2 $\frac{17}{60}$

So you have two 12-inch sections and an additional 3.4-inch section.

3. The curve C with equation y=f(x) is such that, dy/dx = 3x^2 + 4x +k

Andreas93 [3]

a. Given that y = f(x) and f(0) = -2, by the fundamental theorem of calculus we have

$\displaystyle \frac{dy}{dx} = 3x^2 + 4x + k \implies y = f(0) + \int_0^x (3t^2+4t+k) \, dt$

Evaluate the integral to solve for y :

$\displaystyle y = -2 + \int_0^x (3t^2+4t+k) \, dt$

$\displaystyle y = -2 + (t^3+2t^2+kt)\bigg|_0^x$

$\displaystyle y = x^3+2x^2+kx - 2$

Use the other known value, f(2) = 18, to solve for k :

$18 = 2^3 + 2\times2^2+2k - 2 \implies \boxed{k = 2}$

Then the curve C has equation

$\boxed{y = x^3 + 2x^2 + 2x - 2}$

b. Any tangent to the curve C at a point (a, f(a)) has slope equal to the derivative of y at that point:

$\dfrac{dy}{dx}\bigg|_{x=a} = 3a^2 + 4a + 2$

The slope of the given tangent line $y=x-2$ is 1. Solve for a :

$3a^2 + 4a + 2 = 1 \implies 3a^2 + 4a + 1 = (3a+1)(a+1)=0 \implies a = -\dfrac13 \text{ or }a = -1$

so we know there exists a tangent to C with slope 1. When x = -1/3, we have y = f(-1/3) = -67/27; when x = -1, we have y = f(-1) = -3. This means the tangent line must meet C at either (-1/3, -67/27) or (-1, -3).

Decide which of these points is correct:

$x - 2 = x^3 + 2x^2 + 2x - 2 \implies x^3 + 2x^2 + x = x(x+1)^2=0 \implies x=0 \text{ or } x = -1$

So, the point of contact between the tangent line and C is (-1, -3).

Can you help me please? explain why its a yes or no.

Rashid [163]

Answer: No

Step-by-step explanation: it’s a no because. 19 - 15 does not equal out to 7 19 - 15 is 4 and that’s the wrong answer for 19 -15

hope this helps and is the right answer!
