Answer:

$slope=\frac{1-(-3)}{(-7-4)}= -\frac{4}{11}$

Step-by-step explanation:

Formula to calculate slope (m) is given as

$m=\frac{x_{2}- x_{1}}{y_{2}- y_{1}}$

here

$(x_1, y_1)=(-3, 4)$

and

$(x_2, y_2)=(1, -7)$

A projectile is launched upward from a height of 704 feet with an initial velocity of 112 ft/s. The equation gives the height h

Feliz [49]

We are given the data ho equal to 704 feet and vo equal to 112 feet per second. We apply then kinematics equation: h = ho + vot - 1/2 gt2. Substituting to the given equation,
h = 704 + 112t - 1/2 * 32*t2when h is equal to zero,0 = 704 + 112t - 1/2 * 32*t2t is equal to 11 seconds

Write the equation of the line that

zlopas [31]

Answer:

y=-1/2x+2

Step-by-step explanation:

First, the slope of perpendicular line have negative reciprocal coefficients. In this case the coefficient is 2, The reciprocal of 2 is 1/2 and the negative of 1/2 is -1/2. So x will have a coefficient of -1/2.

Second, find the equation with a slope of -1/2 that passes through (-2,3). There are a few ways to do this. I like to plug the given x value into the expression -1/2x, so -1/2(-2) which equals positive 1 and for the line to pass through the point (-2,3) you need to add 2. So: y=-1/2x+2

determine if l || m based on the information given on the diagram. If yes, state the converse that proves the lines are parallel

kirza4 [7]

Answer/Step-by-step explanation:

1. YES.

Converse: If same side interior angles are supplementary, then l || m. (Same side interior angles)

Since the sum of the two same side interior angles, 65° and 115°, equals 180°, therefore, l || m.

2. YES.

Converse: if two angles angles are a linear pair, they are supplementary, therefore l || m. (Linear pair)

Thus,

128° + 53° = 180°.

3. YES.

Converse: if two angles are corresponding angles and congruent, therefore l || m. (Corresponding angles).

Thus,

The indicated angles which are equal to 90°, are corresponding angles therefore, l || m.

4. YES

Converse: if two alternate exterior angles are congruent, then l || m. (Alternate exterior angles)

Thus, the two exterior angles are congruent, therefore l || m.

Plllllllllzzzzzzzzzzzzzzzzz helpppp meeeeeeeeeeeeeeeeeee

DochEvi [55]

Step-by-step explanation:

radius(CE)=diameter/2=9

EF=8inch

DE=8/2=4inch

pythagorean theorem:

im right triangle,

a^2+b^2=c^2

4^2+b^2=9^2

16+b^2=81

b^2=81-16

b^2=65

b=√65

√65≈8.06
