Answer:

ΔAXC ~ ΔCXB ; and ΔACB ~ ΔAXC  

Step-by-step explanation:

We must match up corresponding angles in the similarity statements.

∠A in ΔAXC will match ∠A in ΔABC as well as ∠C in ΔCXB.

∠X in ΔAXC will match ∠C in ΔABC as well as ∠X in ΔCXB.

∠C in ΔAXC will match ∠B in ΔABC as well as ∠B in ΔCXB.

Using this information, the only ones that match are ΔAXC ~ ΔCXB  and ΔACB ~ ΔAXC.

If another line is perpendicular to the line shown on the graph, what must be its slope
Shtirlitz [24]

It's B

Slope is negative, the other must be positive due to m1 x m2 = - 1

m1 = -2/5

The diagram shows a gradient of -2/5. So, the

reciprocal of this valve to make - 1 is 5/2 (which is the - 2/5 flipped upside down, but positive)

-2/5 x 5/2 = - 10/10 (or - 1)

Thus, the perpendicular line to this has a gradient of 5/2.

Hope this helps!

(a) Find an approximation to the integral 2 (x2 − 4x) dx 0 using a Riemann sum with right endpoints and n = 8. R8 =
denpristay [2]

Answer:

Step-by-step explanation:

\int\limits^2_0 {(x^2-4x)} \, dx       n=8     f(x) = x² - 4x

convert [0,2] into 8 subintervals

width of each interval is

\delta x =\frac{2-0}{8}=0.25

All subintervals are:

[0, 0.25], [0.25, 0.5], [0.5, 0.75], [0.75, 1], [1, 1.25], [1.25, 1.5], [1.5, 1.75] and [1.75, 2]

Let, x_i be the right end point of each interval i=1,..8

x_1=0.25, x_2=0.5, x_3=0.75, x_4=1, x_5=1.25, x_6=1.5, x_7=1.75, x_8=2

Reiman sum is

R_8=\delta x[f(x_1)+f(x_2)+...f(8)]\\\\0.25[f(0.25)+f(0.5)+...+f(2)]\\\\0.25\times[-23.25]\\=-5.8125

WILL MARK BRAINLIEST!! Multiply. −1/2⋅3/4 a)−2/3 b) −3/8 c) 3/8 d)2/3
Rom4ik [11]
<h3>Answer:  B)  -3/8</h3>

Explanation:

When multiplying fractions, we multiply the numerators together, and the denominators are handled separately.

The numerators in this case are -1 and 3. They multiply to -3

The denominators multiply to 2*4 = 8

So that's how we end up with -3/8 as the final answer

This fraction cannot be reduced any further, because 3 and have 8 no factors (other than 1) in common.
