write x≤58 in interval notation.
The x ≤ 58 in interval notation = (-∞, 58]
In this question, we have been given an inequality x ≤ 58
We need to write given inequality in interval notation form.
We know that, an interval notation a way to describe a subset of real numbers by the numbers that bound them.
If we draw given inequality on the number line, then it would be as shown below.
x ≤ 58 represents that, x takes all values which are less than or equal to 58.
So, the interval notation would be (-∞, 58]
Therefore, the x ≤ 58 in interval notation = (-∞, 58]

Simplify the expression by combining like terms
Answer:
[tex] \sf \: {7a}^{2} + 6a + 4 [/tex]
Step-by-step explanation:
Given expression,
→ 1 + 5a + 7a² + a + 3
Let's simplify the expression,
→ 1 + 5a + 7a² + a + 3
→ (7a²) + (5a + a) + (1 + 3)
→ (7a²) + (6a) + (4)
→ 7a² + 6a + 4
Hence, answer is 7a² + 6a + 4.

Find volumeof right circular cone having base radius 14cm and slant height 14.8cm.
Answer:
The cone has a volume of approximately 982.5 cubic centimetres.
* That answer sounds off to me, but I'm not sure. You might want to run through the logic yourself and see if you get the same results.
Step-by-step explanation:
The volume of a cone is one third that of a cylinder with the same height and base radius. In other words:
[tex]v = \pi r^{2} \frac{h}{3}[/tex]
But before using that, we need to know the value of h, height. What we are instead given is the slant height, or the length from tip to edge.
We can use that slant height along with the base radius to get the cone height, as the three of them are the edges of a right triangle, with slant height being the hypotenuse.
To get the height then we can say
[tex]h = \sqrt{s^{2} - r^{2}}[/tex]
Where h is height, s is slant, and r is radius.
[tex]h = \sqrt{14.8^{2} - 14^{2} }[/tex]
[tex]h = \sqrt{219.04 - 196}[/tex]
[tex]h = \sqrt{23.04}[/tex]
[tex]h = 4.8[/tex]
A very squat cone indeed.
Now we can plug that and the radius into the actual cone equation:
[tex]v = \pi (14cm)^{2} \frac{4.8cm}{3}\\= \pi 196cm^2 * 1.6cm\\\approx 985.2 cm^3[/tex]

What is the image point of (1, 2) after a translation right 5 units and up 3 units?
Therefore the image point of (1, 2) is (6, 5)
Given point is (1, 2) considered as (x, y)
We know that in the coordinate axis horizontal line represents the x-axis and the vertical line represents the y-axis.
In that, a point that moves right means it goes positive x-axis.
If the point moves left means it goes negative x-axis.
If the point moves up means it goes positive y-axis.
If the point moves down means it goes negative y-axis.
By using the above points we can solve this question as
Given we need to find the image point of (1, 2) after a translation right 5 units and up 3 units.
Now the point on the x-axis changes to 5 units right as
= x + 5
= 1 + 5
= 6
Now the point on the y-axis changes to 3 units up as
= y + 3
= 2 + 3
= 5
Therefore the image point of (1, 2) is (6, 5).

Kari's paper cup holds 6 fluid ounces. If one ounce is equivalent to 29.6 milliliters, how many milliliters does her paper cup hold?
Answer:
Equivalent measurements: teaspoon, ounce, pint, pound
You will find a table of equivalent measurements in the back of many cookbooks:
1 tablespoon = 3 teaspoons
1 cup = 16 tablespoon = 8 ounces
1/4 cup = 4 tablespoons
1/3 cup = 5 tablespoons plus 1 teaspoon
1 pint = 2 cups = 16 ounces
1 quart = 4 cups (2 pints) = 32 ounces
1 gallon = 4 quarts
1 pound = 16 ounces
1/2 pound = 8 ounces
1/4 pound = 4 ounces
Note that a pint is 16 ounces of volume, while a pound is 16 ounces of weight. The popular rhyme "A pint's a pound, the world around" can help you remember this, but keep in mind that they're not really equivalent.
Doubling a recipe can be easy (just put in two of each measurement), but what if you need to divide a recipe in half? Here are some measurements that may help:
Measurement 1/2 Measurement
1/8 teaspoon just a dash
1 tablespoon 1 1/2 teaspoons
1/4 cup 2 tablespoons

George is driving his car. At the end of 2 hours he has driven 94 miles, and at the end of 4 hours he has driven 238 miles. What is the average rate of change? Type your numerical answer below.
47 miles
Step-by-step explanation:
since 2 hours is 94 miles and 4 hours is 238 miles, you can take the 94 and divide by 2 to get how many miles for 1 hour.
The average rate of change will be;
⇒ 72 miles per hour
What is Division method?
Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
George is driving his car. At the end of 2 hours he has driven 94 miles, and at the end of 4 hours he has driven 238 miles.
Now,
Since, We know that;
⇒ Speed = Distance / Time
Hence, We can formulate;
⇒ The average rate of change = (238 - 94) / (4 - 2)
= 144 / 2
= 72
Thus, The average rate of change will be;
⇒ 72 miles per hour
