Answer:

(1,6)

Step-by-step explanation:

We are given that the vertices of triangle ABC are  A at (1,2),B at (1,6) and C at (5,6).

We have to find the coordinates of the orthocenter.

Distance formula: \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Using distance formula

AB=(1-1)^2+(6-2)^2=16

BC=(5-1)^2+(6-6)^2=16

AC^2=(1-5)^2+(2-6)^2=32

AC^2=AB^2+BC^2

Hence, the triangle is a right triangle because it satisfied Pythagoras theorem

(Hypotenuse)^2=(Base)^2+(Perpendicular\;side)^2

The orthocenter is the intersection of three  altitudes of triangle .The orthocenter of right triangle is the vertex of triangle .

The vertex of triangle is at B.

Therefore, the ortho-center of triangle ABC is B(1,6).

What is the surface area of this figure below?
ivann1987 [24]

Answer:

answer: 189

Step-by-step explanation:

Formula to find triangles area is base x height ÷ 2 So... 7 x 10 = 70 70 ÷ 2 = 35 Now sense we have 4 identicle triangles we will just do 35 × 4 amd 35 × 4 = 140 now for the square its simply just base x height so 7 × 7 = 49 now we will add these up...140 + 49 = 189 so 189 is the area. Hope this helps!

Help please and thank you

Remember
(a^b)^c=a^{bc}
and
\frac{x^a}{x^b}=x^{a-b}


so

\frac{(7^2)^5}{7^{-6}}=
\frac{7^{2*5}}{7^{-6}}=
\frac{7^{10}}{7^{-6}}=
7^{10-(-6)}=
7^{10+6}=
7^{16}

the answer is D

Im dum on this but smart on other things look at points too...
Over [174]

Step-by-step explanation:

Whole numbers = Natural numbers + "0"

Integers = Whole numbers + Negative counterparts

Since the set do contains negative numbers, only Rational numbers and Integers are correct. (D)
