OLga [1]

Answer: 1 1/2 yards of yarn

Step-by-step explanation: For this problem, we will simply be multiply 1/2 yard by 3 to get the amount of yard that Ahlam will need.

1/2 x 3/1 = 3/2 or 1 1/2 yards of yarn. Basically you multiply the top of the fractions first (1 x 3) = 3 Then, you multiply the bottom of the fractions second (2 x 1) = 2 (3/2 or 1 1/2)

F(x)=6x^2+10x−1 How many distinct real number zeros does f have?

Nonamiya [84]

Answer:

Here, $D>0$ , hence the quadratic equation has two distinct real roots.

Step-by-step explanation:

Given quadratic equation is $6x^{2} +10x-1$ .

Let, the quadratic equation is $ax^{2} +bx+c$ [where, $a,b,c$ are the constants]

The Discriminant $(D)=b^{2}-4ac$

Case $1$ : $b^{2}-4ac>0$ , if the discriminant is greater than $0$ , it means the quadratic equation has two real distinct roots.

Case $2$ : $b^{2}-4ac$ , if the discriminant is less than $0$ , it means the quadratic equation has no real roots.

Case $3$ : $b^{2}-4ac=0$ , if the discriminants is equal to $0$ , it means the quadratic equation has two real identical roots.

Now,

we have $6x^{2} +10x-1$ , where $a=6,b=10,\ and\ c=-1$

∴ $D=b^{2}-4ac$

$=(10)^{2}-(4\times 6\times\ -1)$

$=100+24$

$= 124$

Here, $D>0$ , hence the quadratic equation has two distinct real roots.

Andy promises opie that he will give him 5000 upon his graduation from college at mayberry u. How much must andy invest today to

san4es73 [151]

Answer: Andy should invest RS. 2784.19 for 12 years .

Step-by-step explanation:

Since we have given that

Amount = Rs. 5000

Time = 12 years

Rate of interest = 5%

So, We need to find the sum:

Using "Compound interest" , we get :

$A=P(1+r)^t\\\\5000=P(1+0.05)^{12}\\\\5000=P(1.05)^{12}\\\\\dfrac{5000}{1.05^{12}}=P\\\\2784.19=P$

Hence, Andy should invest RS. 2784.19 for 12 years .
