Answer:

What ever it is, it should be minus. a = - 2

Step-by-step explanation:

Givens

v1 = - 2

v2 = - 10

t = 4 seconds

formula

a = (vf - vi)/t

Solution

a = (-10 - (-2)) / 4

a = (-10 + 2) / 4

a = (-8)/4

a = -2 m/s^2

Solving a _____ is the process of calculating unknown side lengths or angle measures of a triangle if certain of the side length
Ray Of Light [21]
ANSWER

C) Triangle

EXPLANATION

Solving a triangle is the process of calculating unknown side lengths or angle measures of a triangle if certain of the side lengths and/or angle measures are known.

We use the sine rule and cosine rule to find the missing sides and angles.

If the triangle has a right angle, then this is a special case, where we can use the trigonometric ratios and the Pythagoras theorem to find the unknown angles and sides.

Convert 2000 Swiss francs to Dutch guilders
Shtirlitz [24]

Answer:

2000 swiss francs equals 3920 Dutch Guilders!

Step-by-step explanation:

One Swiss Franc equals 1.96 Dutch Guilders. Having said this, we can come up with the following equation:

D = 1.96S

Where 'S' represents the swiss francs and 'D' the Dutch Guilders. Now, to convert 2000 Swiss francs, we just need to plug the value into the equation:

D = 1.96(2000) = 3920

So, 2000 swiss francs equals 3920 Dutch Guilders!

I need help with this question asap pleaseeeeee
Harman [31]

Answer:

y = 3\sqrt{7}

Step-by-step explanation:

The two inner right triangles are similar, thus the ratios of corresponding sides are equal, that is

\frac{y}{9} = \frac{7}{y} ( cross- multiply )

y² = 63 ( take the square root of both sides )

y = \sqrt{63} = \sqrt{9(7)} = \sqrt{9} × \sqrt{7} = 3\sqrt{7}

What is the multiplicity of the root 2 in the equation x^3-8x^2+20x-16=0?
mote1985 [20]
Factoring the cubic you get: <span>(x - 2)^2 (x-4) , so we know the multiplicity is the amount of times a root shows in an equation because the equation (x-2) has a exponent of 2 that means the root 2 has a multiplicity of 2.</span>
