Multiply the first and last term.  Now find two numbers that when you multiply gives you that product and when you add them gives you the middle term.  Replace the middle term with those two numbers and factor using the grouping method.

10w² - 37w + 15

                          10 x 15 = 150 (1 x150, 2 x 75, 3 x 50, 5 x 30, 6 x 25, 10 x 15)

None of those pairs have a sum of -37 so this polynomial is prime.

4z² + 4z - 3

                   4 x -3 = -12 ( -1 x 12, -2 x 6, -3 x 4)  ⇒ -2 + 6 = 4

= 4z² - 2z   + 6z - 3

= 2z(2z - 1)   +3(2z - 1)

= (2z + 3)(2z - 1)

= 3(6v² + 4v    -9v - 6)

= 3[2v(3v + 2)  -3(3v + 2)]

= 3(2v - 3)(3v + 2)

The correct answer is y=−1/16

Answer:

A. [tex]y=-\frac{49}{16}[/tex]

Step-by-step explanation:

Since, the directrix of a parabola [tex](x - h)^2 = 4p (y - k)[/tex] is,

y = k - p

Here, the given parabola,

[tex]\frac{1}{4}(y+3)=(x-2)^2[/tex]

By comparing,

We get,

k = - 3,

[tex]4p=\frac{1}{4}\implies p=\frac{1}{16}[/tex]

Hence, the directrix of the given parabola is,

[tex]y=-3-\frac{1}{16}[/tex]

[tex] y=\frac{-48-1}{16}[/tex]

[tex]\implies y = -\frac{49}{16}[/tex]

Option 'A' is correct.

1 1/3 cups of raisins are needed to make 1/2 of a recipe

To find the quantity of raisins for half of the recipe, which originally called for 2 2/3 cups, you'd divide 2 2/3 cups by 2, which equals 1 1/3 cups.

This is a question about fractions and division. If a full recipe requires 2 2/3 cups of raisins and you want to make just 1/2 of the recipe, you need to divide the quantity of the raisins by 2.

In fraction form, 2 2/3 is equivalent to 8/3 (as 2*3 + 2 = 8). Then, to find half of this amount, we divide 8/3 by 2. We can do this by multiplying 8/3 by 1/2, which gives us 4/3. Therefore, 1/2 of the recipe requires 4/3, or 1 1/3 cups of raisins.

The graph which  represents the equation y = -2x+3 is Option (B)

A straight line , say y = mx + c can be plotted on the graph by checking its y intercept (c), slope of the following curve (m) and satisfying the points on the x and y coordinates of the following graph.

Following these simple steps, we can easily plot the graph for any straight line.

The equation given is y = -2x + 3 .

First of all the graph will have a negative slope as the slope of the straight line is -2 .

Checking the graph in Option (B), we have

Answer: 684 divided by 57=12

Step-by-step explanation:(with reference to the figure)

To find  684 divided by 57 by partial quotients .

Here dividend= 684 and divisor =57

Step 1: Write easy factors of divisor that is nearest to the dividend as follows

57×2=114

57×3=171

57×5=285

57×10=570(nearest easy factor)

Step 2: Now subtract 570 from 684 ,we get 114 then subtract 114=57×2 from it we get 0.

Step 3: Adding the factors we have used in step 1 and 2 ,it will give required quotient=10+2=12

i.e. 684=57(10)+57(2)

The question in English

A small farmer in the interior of Par, when measuring his rectangular terrain, realized that his dimension is in reason 5/7. If the terrain area is 2240 m2, then its largest dimension in meters is

Let

x--------> the smallest dimension of the rectangular terrain

y--------> the largest dimension of the rectangular terrain

we know that

the area of the rectangular terrain is

[tex]A=x*y[/tex]

[tex]A=2,240\ m^{2}[/tex]

so

[tex]2,240=x*y[/tex] -------> equation A

[tex]\frac{x}{y}=\frac{5}{7}[/tex]

[tex]x=\frac{5}{7}y[/tex] -------> equation B

The denominator of a fractional exponent represents the degree of root.

For example

[tex]x^{\frac{1}{3}} = \sqrt[3]{x}\\x^{\frac{1}{4}} = \sqrt[4]{x}\\x^{\frac{1}{5}} = \sqrt[5]{x}[/tex]

The denominator of a rational exponent represents the root or nth root of the base number. It is expressed in the form of a fraction where the numerator represents the power and the denominator represents the root or nth root. Rational exponents are used in simplifying expressions and performing calculations involving roots and powers.

The denominator of a rational exponent represents the root or nth root of the base number. A rational exponent is expressed in the form of a fraction, where the numerator represents the power to which the base is raised, and the denominator represents the root or nth root. For example, in the rational exponent 3/2, the base number is raised to the power of 3 and then the cube root is taken.

When the numerator of the rational exponent is 0, it signifies that the number is raised to the power of 0, which always results in 1. On the other hand, when the denominator is 1, it signifies that there is no root involved, and the number is simply raised to the power indicated by the numerator.

Understanding rational exponents is essential in simplifying expressions, solving equations, and performing calculations involving roots and powers.

To factor the expression 5ac + 10ab - 2c^2 - 4bc, we first factor out common factors from the pairs of terms which results in 5a(c + 2b) - 2c(c + 2b). Then, we factor out the common binomial (c + 2b) to get the fully factored form: (5a - 2c)(c + 2b).

The expression given is 5ac + 10ab - 2c^2 - 4bc. To factor this expression, we need to look for common factors in the terms. Let's take each pair of terms and factor it.

For the first two terms (5ac and 10ab), the common factor is 5a. Factoring these gives: 5a(c + 2b).

The last two terms (-2c^2 and -4bc), -2c is the common factor. Factoring these gives: -2c(c + 2b).

So our expression becomes 5a(c + 2b) - 2c(c + 2b). Finally, we factor out the common binomial term (c + 2b) to get the fully factored form: (5a - 2c)(c + 2b).

Step-by-step explanation:

To round 17,509 to the nearest thousand, you look at the hundreds digit. If it's 5 or above, you round up. Therefore, 17,509 rounded to the nearest thousand is 18,000.

To round the number 17,509 to the nearest thousand, we first need to look at the digit in the hundreds place; in this case, it's 5. In rounding, if this digit is 5 or above, we round up the preceding number. Since the digit in the hundreds place is 5, we round up the number in the thousand's place from 7 to 8 making the number 18,000. On the other hand, if the digit in the hundreds place was 4 or lower, we would keep the number in the thousands place the same. So, 17,509 rounded to the nearest thousand is 18,000.
