Answer:

4. Isosceles and Obtuse

5. B

6. A, B, D

Step-by-step explanation:

4.

An Isosceles Triangle has 2 or more congruent sides, and it states that it is obtuse.

5.

An acute isosceles is B because there is at least 2 congruent sides and it is all acute (angles less than 90 degrees)

6.

It is a quadrilateral (4 sides), rectangles (2 pairs of parallel sides and 4 right angles), and a parallelogram (2 pairs of parallel sides)

5/3 divide by 3 would be 5/9 so your answer would be C) 5/9.

5/3 * 1/3

5 * 1 over 3 * 3

5 over 3 * 3

So in total the answer would be C) 5/9.

The line tangent to the graph of g(x) = x^{3}-4x+1 at the point (2, 1) is given by the formula
Usimov [2.4K]

well, about A and D, I just plugged the values on the slope formula of

\bf \begin{array}{llll} g(x)=x^3-4x+1\\ L(x) = 8(x-2)+1 \end{array} \qquad \begin{cases} x_1=1.9\\ x_2=2.1 \end{cases}\implies \cfrac{f(b)-f(a)}{b-a}

for A the values are 8.01 and 8.0, so indeed those "slopes" are close. \textit{\huge \checkmark}

for D the values are -2.25 and 8.0, so no dice on that one.

for B, let's check the y-intercept for g(x), by setting x = 0, we end up g(0) = 0³-4(0)+1, which gives us g(0) = 1.

checking L(x) y-intercept, well, L(x) is in slope-intercept form, thus the +1 sticking out on the far right is the y-intercept, so, dice. \textit{\huge \checkmark}

for C, well, the slope if L(x) is 8, since it's in slope-intercept form, the derivative of g(x) is g'(x) = 3x² - 4, and thus g'(0) = -4, so no dice.

for E, do they intercept at (2,1)?  well, come on now, L(x) is a tangent line to g(x), so that's a must for a tangent. \textit{\huge \checkmark}

for F, we know the slope of the line L(x) is 8, is g'(2) = 8?  let's check

recall that g'(x) = 3x² - 4, so g'(2) = 3(2)² - 4, meaning g'(2) = 8, so, dice. \textit{\huge \checkmark}

Will mark brainliest to whoever answers correctly first!!!

To find the volume, you do area multiplied by thickness( or height)
In this example, you do (1/2*9*6)*10 which is 270
hope I helped ;)

If f(x) = -x^3 + 2x^2 - 3, find f(2).<br><br> A) -19<br> B) -3<br> C) -1<br> D) 5
AfilCa [17]

Answer:

B

Step-by-step explanation:

To evaluate f(2) substitute x = 2 into f(x), that is

f(2) = - (2)³ + 2(2)² - 3 = - 8 +2(4) - 3 = - 8 + 8 - 3 = - 3
