H(x)=x²-5 Find h(-7)

Mathematics
2 answers:
anastassius [24]2 years ago

Answer:

h (-7) = 44

Step-by-step explanation:

when working with a function, when we place a value, replacing x, in parentheses next to the function, we are to find the function by replacing x with that value.

Essentially, we need to replace x with -7. [replace meaning substitute]

h (x) = x² - 5

h (-7) = (-7)² - 5

h (-7) = 49 - 5

h (-7) = 44

so, h (-7) = 44

note: ² means to square a number (to multiply that number by itself)

(-7)² ->  - 7  ·  - 7 = 49

hope this helps!!

Answer:

h(x) = 44

Step-by-step explanation:

h(x) = x² - 5, h(-7) means x = -7

h(x) = (-7)² - 5

h(x) = 49 - 5

h(x) = 44

How many triangles can be formed with segments measuring 4. 7 m, 1. 6 m, and 2. 9 m? none one more than one.
Svet_ta [14]

The sum of the length of the two sides of the triangle must be greater than the length of the third side. None of the triangles is formed. Then option A is correct.

<h3>What is the triangle?</h3>

Triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.

The sides of the triangle are 4.7 m, 1.6 m, and 2.9 m.

The condition will be

1.6 + 2.9 \ngtr  4.7

We know that the sum of the length of two sides of the triangle must be greater than the length of the third side.

Hence, none of the triangles is formed.

Thus, option A is correct.

More about the triangle link is given below.

One stack has 6 cups, and its height is 15 cm. The other one has 12 cups, and its height is 23 cm. How many cups are needed for
Ronch [10]

Answer:

Given

Number of stacks = 2

Stack 1 = 6 cups; h1 = 15cm

Stack 2 = 12 cups; h2 = 23cm

Let's first find the average:

With an average of 4/3, to obtain the number of cups needed to obtain a height of 50m, we have:

50 / (4/3)

= 50 * 3/4

= 150/4

= 37.5

From the answer, we can see that the number of cups is not really proportional to the height of the stack, because the average of stack one and stack 2 are different.
