Answer:

Step-by-step explanation:

Given the polynomial P(x) = x^2-3x-10

To check that the remainder is zero if divided by x - 5, we will first have to equate x - 5 to zero and get x;

x - 5 = 0

x = 5

Then find P(5)

P(5) = 5^2 - 3(5) - 10

P(5) = 25 - 15 - 10

P(5) = 25-25

P(5) = 0

This shows that x - 5 is a factor of the polynomial since P(5) gave us zero according to the factor theorem

Answer:

let their age be x and y

x=y.......1st equation

2

now,

product of their age

x+y=63

y +y=63 (putting the value of x=y/2)

3y =126

y=126

3

y=42

hence,

age of jessica is y =42.

Answer:

1:10

Step-by-step explanation:

1 hour is 60 minutes, so the ratio is 6:60.

To simplify, divide both sides by 6.

Thus, you get:

1:10.

Answer:

Step-by-step explanation:

z varies inversely

so z=a/x^2

9=a/(2/3)^2

9=a/(4/9)

9=9a/4

a=4

z=4/x^2

z=4/(5/4)^2

z=4/(25/16)

z=64/25

If z varies inversely as x², it is given by the equation z = 4/x². When x = 5/4, z = 2.56

An equation is an expression that shows the relationship between two or more numbers and variables.

z varies inversely as x². Let k represent the constant of proportionality, hence:

z = k/x²

z = 9 when x = 2/3, hence:

9 = k / (2/3)²

k = 4

z = 4/x²

When x = 5/4:

z = 4 / (5/4)²

z = 2.56

If z varies inversely as x², it is given by the equation z = 4/x². When x = 5/4, z = 2.56

Answer:

y>2x-5

Step-by-step explanation:

-2y+4x<10

-2y<10-4x

divide by -2 to isolate the y

y>-5+2x

Since we are dividing by a negative the sign flips.

Our final answer is y>2x-5

Answer:

-8

Step-by-step explanation

2 to the power of -1 = 0.5

5 to the power of -1 = 0.2

0.5/0.2 = 2.5

So,

(2.5)2 x -5/8 to the power of -1

-5/8 = -0.625

-0.625 to the power of -1 = -1.6

So,

(2.5)2 x -0.625

5 x -0.625

= -8

Answer:

-8

Step-by-step explanation:

(2^-1 ÷ 5^-1) = 5/2

(5/2) x 2 = 10/2 or 5

-5/8 ^-1 = - 8/5

5 x - 8/5 = -40/5 or -8

Answer:

1/12

Step-by-step explanation:

Since the two rolls are independent, then the chance of getting a 6 in the first and an odd number in the second is obtained by multiplying the two probabilities.

1/6 is the probability of rolling 6, 1/2 is the probability of rolling an odd number

1/6 times 1/2 is 1/12

Answer:

The decimal is 0.46

Step-by-step explanation:

Given

Less than 0.8

Greater than 0.02

Required

Determine the decimal

Let the decimal be x

Such that:

[tex]x < 0.8[/tex] and [tex]x > 0.02[/tex]

Rewrite as:

[tex]x > 0.02[/tex] and [tex]x < 0.8[/tex]

Rewrite as:

[tex]0.02 < x[/tex] and [tex]x < 0.8[/tex]

This can be merged to give:

[tex]0.02 < x<0.8[/tex]

From the list of given options, only 0.46 fall in this range because:

[tex]0.02 < 0.46<0.8[/tex]

So:

[tex]x = 0.46[/tex]

7(x + 9 ) - x

Explanation:

the quantity x plus 9 is written x + 9 , plus meaning add.

times the quantity means multiply the quantity x + 9 multiplied by 7

this is written 7(x + 9 )

finally minus x means subtract x

putting it all 'together' we get 7(x + 9 ) - x

Choice c. [tex]\sqrt{12}[/tex]

Step-by-step explanation:

Vectors

Suppose we have a vector v defined as

[tex]\vec v=a\mathvf{i}+b\mathvf{j}[/tex]

The magnitude of the vector is:

[tex]\mid\mid\vec v\mid\mid=\sqrt{a^2+b^2}[/tex]

On the other hand, the dot product of the vector by itself is:

[tex]\vec v\cdot\vec v=a*a+b*b=a^2+b^2[/tex]

Note the relation between these two operations is:

[tex]\mid\mid\vec v\mid\mid=\sqrt{\vec v\cdot\vec v}[/tex]

Since we are given:

[tex]\vec v\cdot\vec v=12[/tex], then:

[tex]\mid\mid\vec v\mid\mid=\sqrt{12}[/tex]

Choice c) [tex]\sqrt{12}[/tex]
