Which statement best explains whether △PQR is congruent to △XYZ?

1 answer:

3 0

<span>Two geometic shapes are congruent if one can be mapped to the other only by using rigid motions: translations and rigid rotations. The third statement is the only one that is true for any triangles â–łPQR and â–łXYZ, in whichever position they are.</span>

What is the volume of a sphere with a diameter of 10 m, rounded to the nearest tenth of a cubic meter

kirill [66]

Answer:

4188.8 cm^3

Step-by-step explanation:

We can calculate the volume of a sphere by using the following equation:

$\frac{4}{3}\pi r^{3}$

(r=radius)

so let's just plug in what we know

4/3(pi)(10)^3

we can calculate this with a calculator to get 4188.8 cm^3.

For the function f(x)=3xsquared- 2x+5 find f(1) f(-2) and f(a)

Oksanka [162]

$f(x)=3x^2-2x+5\\\\
f(1):\ \ Substitude\ 1 \ as\ x\ into\ function:\\
f(1)=3*1^2-2*1+5=3-2+5=\textbf{6}\\\\
f(-2)\ \ Substitude\ x=-2\\
f(-2)=3*(-2)^2-2*(-2)+5=3*4+4+5=12+4+5=\textbf{21}\\\\
f(a)\ \ substitude\ x=a\\
f(a)=\underline{3a^2-2a+5}$

Help Pls! It's for my Math 4! Scalar Multiplication!

prohojiy [21]

Answer:

Concept: Physics Qualitative Analysis.

Scalar values are constant and compared to vector values they do not have a direction or magnitude or a gradient representation.

Lets get started by setting up the equation
They want us to find 3U-2V
Given U= <6,6> V=<6,-6>
Now we plug in and solve!
3<6,6>- 2<6,-6>
<18,18>-<12,-12>
Subtract
<18-12,18-(-12)>
Hence that gives us a result of <6,30>
Now with the skills you gained solve the rest!!!
