Answer:

1: -1\2

2: 2\4 simplified to 1\2

Step-by-step explanation:

for the first one it rises one and runs two that makes it one over two. 1\2 but since it's going down it will be negative one over two

for the second one it rise two and runs four but that's not an option so we simplify it. we divide the top by two and the bottom by two 2÷2=1 4÷2=2

Slope formula: $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Slope of line one: $-\frac{1}{2}$

Slope of line two: $\frac{1}{2}$

Slope of line three: $-\frac{2}{3}$

Answer:

w = 6.7451

x = 8.0805

Step-by-step explanation:

Find W

Tan(56) = opposite / adjacent

opposite = 10

Adjacent = w

Tan (56) = 10/w

w*Tan(56) = 10

w = 10 / tan(56)

w = 10/ 1.4826

w = 6.7451

Find x

Tan (34) = 10 / (w + x)

Tan (34) = 0.6745

(w + x) * Tan(34) = 10

w + x = 10 / tan(34)

w+ x = 10 / 0.6745

w + x = 14.826

But we found w = 6.7451

6.7451 + x = 14.826

x = 14l826 - 6.7451

x = 8.0805

Find r<br> 25= r•r•8<br> hurry go fast please

ELEN [110]

Answer:

$r = \frac{5}{2\sqrt{2} } \\r = -\frac{5}{2\sqrt{2}}$

Step-by-step explanation:

25= r•r•8 ⇔ 25/8 = r²

then

$r^{2} =(\frac{5}{2\sqrt{2} } )^{2} \\\\Then\\\\r = \frac{5}{2\sqrt{2} } \\Or\\r = -\frac{5}{2\sqrt{2}}$

SOLUTION: a diver jumps from a diving board that is 24 feet above the water. the height of the diver is given by h= -16(t-1.5)(t

lara [203]

Answer:

The diver will hit the water at 1.5 seconds

Step-by-step explanation:

Given

$h= -16(t-1.5)(t+1)$

Required (Missing from the question)

When will the diver hit the water?

To do this, we simply solve for t

When the diver hits the water, the height is 0 (at that point)

So, substitute 0 for h in $h= -16(t-1.5)(t+1)$

$0= -16(t-1.5)(t+1)$

Divide both sides by -16

$\frac{0}{-16} =\frac{-16(t-1.5)(t+1)}{-16}$

$\frac{0}{-16} =(t-1.5)(t+1)$

$0 =(t-1.5)(t+1)$

$(t-1.5)(t+1)=0$

Split

$t - 1.5 = 0$ or $t + 1 = 0$

Solve for t

$t = 1.5$ or $t = -1$

But time (t) can not be negative.

So:

$t = 1.5$

Hence, the diver will hit the water at 1.5 seconds

Determine the slope PLS HELP AND HURRRRRRYYYYYYYYYYYYY

levacccp [35]

Answer:

You see where ANY two intersection of the line touch the grid. Then you do the rise/run (y/x) method.

The answer is 3/4.

Because it rises 3 times and runs 4 times.
