Answer: Parabola

Step-by-step explanation:

Given that c and d are constants, then:

g(x) = (x - c)^2 + d

g(x) = x^2 - 2c x + c^2 + d

g(x) = (1) x^2 - (2c)x + (c^2 + d)

thus, g(x) is a quadratic function, then its graph is a parabola that opens upwards (first coefficient is positive = 1).

Question 17&18. Make x the subject of the formula

aniked [119]

Answer:

17. x = y^2 - 2ay +a^2

18. x = y^2 - a

Step-by-step explanation:

17. Since we want to make x the subject of the formula, we first isolate the square root of x and get

$\sqrt{x}$ = y - a.

squaring both sides,

x = y^2 - 2ay +a^2

18. Since both x and the a are under the square root, we first start by squaring both sides.

So y^2 = x+a.

Isolating the x, we get

x = y^2 - a

Find the value of root 121 + 3 over root 125

NemiM [27]

Answer:

$\mathrm{Decimal:\quad }\:1.25219\\\frac{14\sqrt{5}}{25}$

Step-by-step explanation:

$\frac{\sqrt{121}+3}{\sqrt{125}}\\\sqrt{125}=5\sqrt{5}\\=\frac{\sqrt{121}+3}{5\sqrt{5}}\\\sqrt{121}=11\\=\frac{11+3}{5\sqrt{5}}\\\mathrm{Add\:the\:numbers:}\:11+3=14\\=\frac{14}{5\sqrt{5}}\\\mathrm{Rationalize\:}\frac{14}{5\sqrt{5}}:\quad \frac{14\sqrt{5}}{25}\\=\frac{14\sqrt{5}}{25}$

How many triangles can you construct with the angle measures of 50, 70, and 100?

lidiya [134]

Answer:

Step-by-step explanation:

You can't construct any triangles with those angles. Because when you add all the angles of a triangle, it has to add up to 180. But when we add 50,70, and 100, it equals 220. So you can't construct any triangles.

Hope this helps.<em> (If it does, please mark me brainliest)</em>
