Solve for x and y<br><br>Both questions please ❤️​
zimovet [89]

Answer:

1. x=18, y=6\sqrt{10}

2. x=108, y=180

Step-by-step explanation:

The height of the right triangle drawn to the hypotenuse is the geometric mean of two segments of the hypotenuse (two legs' projections)

1. Use this property, so

CD^2=AD\cdot BD\\ \\6^2=2\cdot x\\ \\36=2x\\ \\x=18

Consider right triangle BCD. By the Pythagorean theorem,

BC^2=BD^2+CD^2\\ \\y^2=18^2+6^2\\ \\y^2=324+36\\ \\y^2=360\\ \\y=\sqrt{360}=6\sqrt{10}

2. Consider right triangleGM*. By the Pythagorean theorem,

G*^2=GM^2+M*^2\\ \\240^2=GM^2+192^2\\ \\GM^2=240^2-192^2=(240-192)(240+192)=48\cdot 432=144^2\\ \\GM=144

Use this property to find x:

GM^2=192\cdot x\\ \\144^2=192\cdot x\\ \\x=\dfrac{144^2}{192}=108

Consider right triangle GMCup. By the Pythagorean theorem,

y^2=x^2+GM^2\\ \\y^2=108^2+144^2\\ \\y^2=32,400\\ \\y=180

Given the function p below, which statement correctly compares the values of p(1) and p(2)? P(x)=4 x
oksano4ka [1.4K]

Answer:

The value of P(2) is twice that of P(1).

Step-by-step explanation:

P(x) = 4x so:

P(1) = 4*1 = 4 and

P(2) = 4*2 = 8.
