Slope 4.2; y-intercept (0,3.4)

umka2103 [35]

Answer:I don't know if you're asking for equation or not cause you didn't mention the question so I'm just gonna write down the equation.

y=4.2x+3.4

Use this formula➡️y=mx+b

m is slope, b is y-intercept , x and y are the points like (0, 3.4)

You said it's the y-intercept but it's not. it's just a point on the graph

Can someone please help me

Ainat [17]

Answer:

Step-by-step explanation:

If the two triangles are similar, then corresponding sides must share a constant ratio. This means that:

$\dfrac{10}{6}=\dfrac{25}{15}=\dfrac{x}{12}$

Let's use the second ratio:

$\dfrac{25}{15}=\dfrac{x}{12}$

Multiply both sides by 12:

$\dfrac{25\cdot 12}{15}=x \\\\x=20$

Hope this helps!

Simplify h= 105sin (0.0698(90+1)) + 105

IrinaK [193]

Answer:

$h= 116.616$

Step-by-step explanation:

we have

$h= 105sin (0.0698(90+1)) + 105$

step 1

Solve (90+1)

$h= 105sin (0.0698(91)) + 105$

step 2

Solve 0.0698(91)

$h= 105sin (6.3518) + 105$

step 3

Solve sin (6.3518)

$h= 105(0.11063) + 105$

step 4

Solve 105(0.11063)

$h= 11.616 + 105$

step 5

Solve 11.616 + 105

$h= 116.616$
