I need help with geometry

astra-53 [7]

Answer:

Step-by-step explanation:

Use the Pythagorean theorem:

a^2 + b^2 = c^2
5^2 + 12^2 = c^2
25 + 144 = c^2
c^2 = 169
13

Note: This also happens to be a Pythagorean triple where all three numbers are integers. These can be memorized.

ΔCAR has coordinates C (2, 4), A (1, 1), and R (3, 0). A translation maps point C to C' (3, 2). Find the coordinates of A' and R

shutvik [7]

Answer:

$A'= (2,-1)$ and $R'=(4,-2)$ under this translation.

Step-by-step explanation:

A translation in $R^{2}$ is a mapping T from $R^{2}$ to $R^{2}$ defined by $T(x,y) = (x + v_1,y+v_2)$ , where $v=(v_1,v_2)$ is a fixed vector in $R^{2}$ .

From the problem we know that $T(2,4)=(3,2)$ , so we need to find the values $v_1$ and $v_2$ such that $T(2,4) = (2 + v_1,4+v_2)=(3,2)$ , so $3=2 + v_1$ and $4+v_2=2$ , thus $v_1=1$ and $v_2=2$ .

Then $T(x,y) = (x + 1,y-2)$ and

$T(1,1)=(1+1,1-2)=(2,-1)=A'$

$T(3,0)=(3+1,0-2)=(4,-2)=R'$

Therefore $A'= (2,-1)$ and $R'=(4,-2)$ . The triangles CAR and C'Q'R' are shown in the figure below.

2/9 divided by 5/6<br>help pleaseee

igomit [66]

Hey there!

$\mathsf{\dfrac{2}{9}\div\dfrac{5}{6}}$

$\mathsf{= \dfrac{2\times6}{9\times5}}$

$\mathsf{2\times 6 = \bf 12}$

$\mathsf{9\times5 = \bf 45}$

$\boxed{\mathsf{=\bf \dfrac{12}{45}}}$

$\large\textsf{BOTH NUMBERS has the Greatest Common Factor (GCF) of 3}$

$\mathsf{= \dfrac{12\div3}{45\div3}}$

$\mathsf{12\div3=\bf 4}$

$\mathsf{45\div3=\bf 15}$

$\boxed{\mathsf{=\bf \dfrac{4}{15}}}$

$\boxed{\boxed{\large\textsf{Answer: }\mathsf{\bf \dfrac{4}{15}}}}\huge\checkmark$

What value is a discontinuity of x squared plus 2 x plus 3, all over x squared minus x minus 12 ?

den301095 [7]

X² + 2x +3

If the discriminent Δ = b²-4.a.c <0 , that means the roots (or the zero value) are nit REAL Number (they are imaginary or complex)

Δ = 2² - 4(1)3) = 4 - 12 = -8

since Δ = - 8 < 0 there are no real roots
