Find the zeros of the function. y=(3x+2)(x+4)

Mathematics
1 answer:
Gennadij [26K]3 years ago
5 0
If (3x+2)(x+4) = 0 then one of the 2 factors ( or both) have to be 0. set each to ,0 and solve for x

3x+2=0 means x =-2/3

if x,+4=0 then x = -4

that's your two zeros

Answer:

u=\frac{9}{t}-\frac{1}{2} a t

Step-by-step explanation:

Step 1: Given equation: 9=\frac{1}{2} a t^{2}+u t

To get u, by subtraction equality property subtract both sides of the equation by  \frac{1}{2} a t^{2}.

\Rightarrow 9-\frac{1}{2} a t^{2}=\frac{1}{2} a t^{2}+u t-\frac{1}{2} a t^{2}  

\Rightarrow 9-\frac{1}{2} a t^{2}=u t  

Step 2: By division equality property, divide both sides of the equation by t.

\Rightarrow \frac{9-\frac{1}{2} a t^{2}}{t}=\frac{u t}{t}

$\Rightarrow \frac{9}{t}-\frac{1}{2} a t=u$  

Therefore, $u=\frac{9}{t}-\frac{1}{2} a t$.

So, in Emily’s physics class, she got $u=\frac{9}{t}-\frac{1}{2} a t$.

Casey wants to buy a gym membership. Gym A has a $150 joining fee and costs $35 per month. Gym B has no joining fee and costs $6
MariettaO [177]

Answer:

Step-by-step explanation:

Gym A has a $150 joining fee and costs $35 per month.

Assuming that Casey wants to attend for x months, the cost of using gym A will be

150 + 35 times x months. It becomes

150 + 35x

Gym B has no joining fee and costs $60 per month.

Again, assuming that Casey wants to attend for x months, the cost of using gym B will be

60 × x months = 60x

A) To determine the number of months that it will both gym memberships to be the same, we will equate them.

150 + 35x = 60x

60x - 35x = 150

25x = 150

x = 150/25 = 6

It will take 6 months for both gym memberships to be the same.

B) If Casey plans to only go to the gym for 5 months,

Plan A will cost 150 + 35×5 = $325

Plan B will cost 60 × 5 = $300

Plan B will be cheaper

Whats is 0.000001 written as a power of ten
siniylev [52]
You need to move the decimal point to be at 1.

Since this is a decimal, the power will be negative.

I had to move the decimal 6 places.

So,

1^-6

I hope this helps!
