Answer:

26

Step-by-step explanation:

You would use the Pythagorean theorem to solve for the last side.

Pythagorean theorem- a^2+b^2=c^2

a and b =sides

c=hypotenuse

Since you are finding the hypotenuse(c), you don't have to rearrange the formula

plug in a and b.

10^2+24^2=c^2

solve

100+576=c^2

676=c^2

do the square root of 676 to get rid of the c<u>^2</u>

26=c

Answer:

u can use "a squared + b squared = c squared"

in this case the two legs are 10 and 24 because they are near the right angle. the hypotenuse is always across from the right angle, so it's the long side that connects the two legs. Now you can plug in 10 and 24 for the pythagorean theorem and solve for the hypotenuse. that would be 10 squared plus 24 squared equal to c squared.

PKE is a triangle and its interior angles therefor sum to 180deg:

P+K+E=180
90+(x+6)+2x=180
96+3x=180
3x=84
x=\frac{84}{3}=28deg

This hyperbola is centered at the
Varvara68 [4.7K]

Answer:

The equation is ( x² / 9 ) - ( y² / 7 ) = 1

Step-by-step explanation:

Given the data in question;

hyperbola is centered at the  origin, this means h and k are all equals to 0.

Vertices: (-3,0) and (3,0)

Since y-coordinates are constant, this implies it is a hyperbola with horizontal transverse axis.

h - a = -3

0 - a = -3

a = 3

Foci: (-4,0) and (4,0)

h - c = -4

0 - c = -4

c = 4

we know that, for a hyperbola

c² = a² + b²

so

⇒ ( 4 )² = ( 3 )² + b²

16 = 9 + b²

b² = 16 - 9

b² = 7

So the equation for the hyperbola will be;

⇒ ( (x-h)² / a² ) - ( (y-k)² / b² ) = 1

so we substitute

⇒ ( (x-0)² / 3² ) - ( (y-0)² / 7 ) = 1

⇒ ( x² / 3² ) - ( y² / 7 ) = 1

⇒ ( x² / 9 ) - ( y² / 7 ) = 1

Therefore, The equation is ( x² / 9 ) - ( y² / 7 ) = 1

Solve for x= ax2 + b = c
alekssr [168]

Answer:

x = ± \sqrt{\frac{c-b}{a} }

Step-by-step explanation:

Given

ax² + b = c ( subtract b from both sides )

ax² = c - b ( divide both sides by a )

x² = \frac{c-b}{a} ( take the square root of both sides )

x = ± \sqrt{\frac{c-b}{a} }

Answer: 99cm^2

Step-by-step explanation:

The area of a parallelogram is the base*the height.

The base is 4+5 = 9 cm.

Therefore, the area of a parallelogram is 9*11 = 99cm^2
