.Find the vertex, zero(s), and y-intercept of the graph of y = x2 + 4x – 5.
scZoUnD [109]

Answer:

Vertex (-2,-9)

zeros: x=1, x=-5

y-intercept: -5

Step-by-step explanation:

When you graph the quadratic equation you obtain the parabola shown in the figure attached.

Find the vertex of the parabola observing the graph, you can that the minimum point of the parabola is at (-2,-9) this is the vertex.

The zeros are the x-intercepts:

x=1; x=-5

And the y-intecept is when x=0 and the parabola cut the y-axis. This is: -5.

PLEASSSSSE I NEED HELP BAD HELP PLEASE

Answer:

See explanation

Step-by-step explanation:

Given the equation 3x-4y=12

A. Create the table of values for at least 4 points.

When x=0,

3\cdot 0-4y=12\\ \\-4y=12\\ \\y=-3

When x=2,

3\cdot 2-4y=12\\ \\-4y=12-6\\ \\-4y=6\\ \\y=-1.5

When x=4,

3\cdot 4-4y=12\\ \\-4y=12-12\\ \\-4y=0\\ \\y=0

When x=6,

3\cdot 6-4y=12\\ \\-4y=12-18\\ \\-4y=-6\\ \\y=1.5

When x=8,

3\cdot 8-4y=12\\ \\-4y=12-24\\ \\-4y=-12\\ \\y=3

Thus, the table is

\begin{array}{cc}x&y\\0&-3\\2&-1.5\\4&0\\6&1.5\\8&3\end{array}

B. Use the table of values to graph the line on the coordinate plane. Plot given points and connect them with the straight line (see attached diagram).

From a boat on the lake, the angle of elevation to the top of a cliff is 26°35'. If the base of the cliff is 85 feet from the bo
Trava [24]
Check the picture below

now, <span>26°35' is just 26bdegrees and 35 minutes

your calculator most likely will have a button [ </span><span>° ' " ]  to enter degrees and minutes and seconds

there are 60 minutes in 1 degree and 60 seconds in 1 minute

so.. you could also just convert the 35' to 35/60 degrees

so </span>\bf 26^o35'\implies 26+\frac{35}{60}\implies \cfrac{1595}{60}\iff \cfrac{319}{12}&#10;\\\\\\&#10;tan(26^o35')\iff tan\left[ \left( \cfrac{391}{12} \right)^o \right]

now, the angle is in degrees, thus, make sure your calculator is in Degree mode
