What is the product of (-4)(7) and why?

Mathematics
1 answer:
Mumz [18]3 years ago

Answer:

The product of (-4)(7) is -28 because you are removing 4 times, the number 7

.

Reason is below.

Step-by-step explanation:

The number which is written first in the multiplication or the product is always multiplied by the second number.

For example

3 × 2 implies three times two which equal to 6

2 × 3 implies two times three which is also equal to 6

Therefore the number written in the first is count as times, the number second.

For example

-3 × 2 implies three times two which equal to -6

Here the product is negative 6

Because if a negative number is multiplied by positive number you will always get the product as negative number.

If a positive numbers multiplied by positive number you will always get the product as a positive number.

For example

3 × 2 implies three times two which equal to 6

If a positive numbers multiplied by negative number you will always get the perfect as a negative number.

For example

3 × -2 implies three times two which equal to -6

If a negative number is multiplied by negative number you will always get the product as a positive number.

For example

-3 × -2 implies three times two which equal to 6

Therefore, the product of (-4)(7) is -28 because you are removing 4 times, the number 7

Find the value of x. Round the length to nearest tenth.
Lady_Fox [76]

From the law of sines, we have

l = h\sin(\theta) = h\cos(\alpha)

where l is the leg we're interested in, h is the hypothenuse, \theta is the angle opposite to l, and \alpha is the angle between l and h.

So, in the first case, we can use

x = 15\sin(35) \approx 8.6

And in the second excercise, we use

x = 11\cos(44) \approx 7.6

10(2^×) + 7(3^×) = 6^× + 70​
Mkey [24]

Answer:

x = 2.81 and 2.096

Step-by-step explanation:

Given the expression

10(2^x) + 7(3^x) = 6^x + 70​

This can also be expressed as;

10(2^x) + 7(3^x) = (2*3)^x + 70

10(2^x) + 7(3^x) = 2^x*3^x + 70

Let a  = 2^x and b = 3^x

10a + 7b = ab + 70

10a + 7b - ab = 70

10a-ab + 7b - 70 = 0

a(10-b)+7(b-10) = 0

a(10-b)-7(10-b) = 0

a-7 = 0 and 10-b = 0

a = 7 and b = 10

Since a = 2^x

7 = 2^x

log 7 = log2^x

log7 = xlog2

x = log7/log2

x = 2.81

Similarly

10 = 3^x

log 10 = log 3^x

log 10 = xlog3

x = log 10/log 3

x = 1/0.4771

x = 2.096

Hence the values of x that satisfies the equation are 2.81 and 2.096
