Answer:

<h3>The answer is option A</h3>

Step-by-step explanation:

Angles in a triangle add up to 180°

Since it's a right angled triangle one of it's angles is 90°

So for angle F we have

F + 25 + 90 = 180

F = 180 - 115

To find GH we use tan

tan 25 = FG / GH

FG = 7m

tan 25 = 7 / GH

GH = 7 / tan 25

To find FH we use sine

sin 25 = FG / FH

sin 25 = 7 / FH

FH = 7/sin 25

Hope this helps you

Okay i am begging all of the math wizards on brainly to help me. it is end of the semester for me and im trying so hard not to f

Travka [436]

Answer:

Ok its pretty straight forward

So for every x its 1

And every y its 4/5

To make life simpler lets just make 4/5 into a whole number

So we can make it into 20/5 which equals 4

To get to 20/5 we multiply 4/5 by 5

So we multiply the x by 5 too

We’d get (5,5)

So you can plot that

And the lines should automatically plug in a different point

You can plug it into negatives

-5, -5

so something between those lines

Like i dontt get how lines work here it Make sure its on the 5,5

I can’t think of an equation but I guess

5=m5

In the Format Y=mx (yes no y intercept because its a direct proportion formula)

Or you can use the format

y/x=m

5/5=m

Or if they suggest it in a y intercept formula

y-mx+b

just plug in like y with 5 and the x with 5.

You can also use the plot (10,8) still works :)

If I’m worng I’m sorry the question is weird and I’m assuming they asking you about Proportional/direct relationships

Sanjay graphs a quadratic function that has x-intercepts of –3 and 7. Which functions could he have graphed?

kykrilka [37]

we will select each options and find zeros

(a)

$g(x)=x^2-4x-21$

for finding x-intercept , we can set g(x)=0

and then we can solve for x

$g(x)=x^2-4x-21=0$

now, we can factor it

$(x-7)(x+3)=0$

we get

$x=7,x=-3$

so, this is TRUE

(b)

$g(x)=(x-3)(x+7)$

we can set it to 0

and then we can solve for x

$g(x)=(x-3)(x+7)=0$

we get

$x=3,x=-7$

so, this is FALSE

(c)

$g(x)=3x^2-12x-63$

we can set it to 0

and then we can solve for x

$g(x)=3x^2-12x-63 =0$

$3(x^2-4x-21) =0$

$3(x-7)(x+3) =0$

$x=-3,x=7$

so, this is TRUE

(d)

$g(x)=-(x+3)(x-7)$

now, we can set it to 0

and then we can solve for x

$g(x)=-(x+3)(x-7)=0$

$x=-3,x=7$

so, this is TRUE

(e)

we have

$g(x)=x^2+4x-21$

now, we can set it to 0

and then we can solve for x

$g(x)=x^2+4x-21=0$

$(x+7)(x-3)=0$

$x=-7,x=3$

so, this is FALSE

The equation yˆ=20646·0.86x estimates the value of a brand of car x years after it was purchased new. Milo purchased this brand

zhannawk [14.2K]

Answer:

$195311

Step-by-step explanation:

Given the expression yˆ=20646*0.86x

Given that the number years 11

And x represent the number of years

Substituting x=11 in the expression for the cost we have

yˆ=20646*0.86(11)

yˆ=20646*9.46

yˆ=195311.16

From the analysis he purchased the car fro $195311
