(√22)(5√2)

= √22 x 5√2

= 5√22x2

= 5√44

= 5√11 x 4

= 5 √11 x √4

= 5 √11 x 2

= 5 x 2 √11

= 10√11

Answer:

11.x=16 12.x=37

Step-by-step explanation:

11.

20^2-12^2=x^2

256=x^2

x=√256

x=16

12.

13^2-5^2=y^2

144=y^2

y=12

y^2+35^2=x^2

12^2+35^2=x^2

1369=x^2

x=37

Which is a y-intercept of the graphed function? (–9, 0) (–3, 0) (0, –9) (0, –3)

Inessa05 [86]

Answer:

The y-intercept of the graphed function is (0,-9)

Step-by-step explanation:

The y-intercept of the graphed function is (0,-9) because the y-intercept is where the point where the line meets with the y-axis, and the point where the line meets with the y axis is (0,-9)

Therefore the answer is

(0,-9)

I hope this helped you.

The ratio of the measure of the sides of the triangle is 1/6: 1/3: 1/4 if the perimeter of the triangle is 13.5 inches find the

marissa [1.9K]

Answer:

The shortest side of the triangle is 3 inches.

Step-by-step explanation:

Given:

The ratio of the measure of the sides of the triangle is 1/6: 1/3: 1/4.

The perimeter = 13.5 inches.

Now, to find the shortest side.

Let the one side be $\frac{1}{6}x$

And the second side be $\frac{1}{3}x$ .

And the third side be $\frac{1}{4}x$ .

According to question:

$\frac{1}{6}x+\frac{1}{3}x+\frac{1}{4}x=13.5$

⇒ $\frac{x}{6}+\frac{x}{3}+\frac{x}{4}=13.5$

Adding all the variables by taking common denominator we get:

⇒ $\frac{9x}{12}=13.5$

Multiplying both sides by 12 we get:

⇒ $9x=162$

Dividing both sides by 9 we get:

⇒ $x=18$

Thus, the sides of the triangle are:

1/6×18=3 inches.

1/3×18=6 inches.

1/4×18=9/2=4.5 inches.

Therefore, the shortest side of the triangle is 3 inches.

Will someone please help me!!! I don’t know the answer to these! I don’t even know if I did them right!

Varvara68 [4.7K]

Answer:

$BD = 12$ units

$AB = 16$ units

$FG=\sqrt{105}$

$EC=4\sqrt{10}$ units

$AC=8\sqrt{10}$ units

Step-by-step explanation:

A circumcenter is the point where the perpendicular bisectors of a triangle intersect.

This means

BD = DC;
BF = FA;
AE = EC.

Since BC = 24 units, then BD = 12 units (half of BC).

Since FA = 8 units, AB = 16 units (twice FA).

Consider right triangle BGF. In this triangle, BF = 8 units (congruent to FA), BG = 13 units. By the Pythagorean theorem,

$FG^2=BG^2-BF^2\\ \\FG^2=13^2-8^2\\ \\FG^2=169-64=105\\ \\FG=\sqrt{105}\ units$

Triangles BFG and AFG are congruent right triangles, then BG = AG. In right triangle AGE, $GE=3$ units, $AG=13$ units. By the Pythagorean theorem,

$AE^2=AG^2-GE^2\\ \\AE^2=13^2-3^2=169-9=160\\ \\AE=\sqrt{160}=4\sqrt{10}\ units$

$AE = EC=4\sqrt{10}\ units$

$AC = 2AE=2\cdot 4\sqrt{10}=8\sqrt{10}\ units$
